<p>I made some research, but nothing worked. I checked the "Show in user interface" checkbox in GNOME Disks, tried to replace the mount option from <code>x-gvfs-show</code> to<code>comment=x-gvfs-show</code>, and my drives are mounted in /media/[username].</p>
<p>I know that I can bookmark the directories where the drive is mounted, but that's not really what I'm looking for, as they look like the usual directory in the sidebar. I would like a clear separation between the drives and the bookmark, or at least, an icon or something. I remember that GNOME Files has this functionality, but it does not work out of the box on Ubuntu, it seems.</p>

<p>I understand that the only way to get libcamera-apps is to compile them from source. I came to this conclusion following these links:</p>

<p><a href="https://www.raspberrypi.com/documentation/computers/camera_software.html#building-libcamera-and-rpicam-apps" rel="nofollow noreferrer">Official Rpi document</a></p>
<p>I am having a lot of trouble following the instructions for building rpicam-apps.</p>
<ol>
<li>It is really unclear if these instructions are valid for Ubuntu, as opposed to RPi-OS.</li>
<li>It is unclear if I should use the version of libcamera in Ubuntu repository, or build it from source from (which branch?) in github.</li>
<li>meson is out of date in Ubuntu 22.04 repository. I have to install it, and there is a lot of confusion over whether or not to use sudo.</li>
</ol>
<p>I do not understand the consequences of using sudo to install meson. Some people recommend it, and some do not! I do know that the choice affects the final installation step.</p>
<p>I have already made numerous attempts at compiling rpicam-apps, but cam and libcamera-vid do not work and cam gives a segmentation fault.</p>
<p>It is difficult to get help because rpi experts think this is a Ubuntu problem and Ubuntu experts think it is a Raspberry Pi problem.</p>

When I create a python virtual environment and try installing packages using pip, the download and installation process take too long. But the installations are smooth and fast in base environment.</p>

Kernel: Linux 6.5.0-26-generic
Python: 3.12.1
pip: 23.3.1

<p>I am new to linux and don't know much, I have tried temporarily disabling Ipv6 as mentioned in this <a href="https://stackoverflow.com/questions/50787522/extremely-slow-pip-installs">stackoverflow answers</a> using following commands, but it still doesn't seem to work.</p>
<pre><code>sudo sysctl -w net.ipv6.conf.all.disable_ipv6=1
sudo sysctl -w net.ipv6.conf.default.disable_ipv6=1
</code></pre>
<p><strong>Edit:</strong>
I am using built in environment created by PyCharm and creating environment in Vscode using following command:</p>
<pre><code>python3 -m venv .venv
</code></pre>
<p>By too slow I mean the download rate, when I install any package suppose pandas then it shows the download speed at something like 900 kbps then it gradually decreases almost to 12 kbps (I haven't stayed any longer to check) also the estimated time for downloading also increases.</p>
<p>And the download rate for kubuntu packages on system are not slow, they occur instantly. Also I tried installing packages in my conda environment and the installations don't take that long when installing with conda but when pip is used, the download rate starts to decrease like before.</p>
<p><strong>Update:</strong> I tried and looked around different versions, and this particular happened while I was trying to install an old version of numpy(1.23.4) and packages that are download through github such as spacy en_core_web_sm.</p>

I had to take it to a shop to confirm that it was the GPU and no other physical damage was the issue. They determined that it was the GPU by inserting another GPU I to the computer and they got it to boot into bios and then into windows, but the thing that is concerning me is that I had windows on the default drive it came with (it was a pre built rig) and I added my 2tb ssd with Ubuntu and made it the default boot drive. After the installation it booted to the grub menu every time and I could pick between the two no problem but they said that when they put the new card in the screen was black for a time then it booted windows. I ordered a new gpu, the same as the one that failed (different manufacturer same chipset) but it has not arrived yet and it's been nagging me why it booted to windows instead of the grub menu. Could the bios have chosen the windows drive because it was easier for compatibility with the card they tested or will I need to reconfigure the bios to boot from the SSD with Ubuntu on it and everything will be back to normal?</p>

1508711 | 1 | null | 2024-03-27T05:58:08.180 | 0 | 19 | <p><strong>Preface and Context:</strong>
I am currently troubleshooting the ROS2/LAN based connection of my UR5 CB3 robotic arm with the Ubunut 22 control comupter and the respective driver. This robotic arm seems to require communication via port 50002, but for some reason my computer refuses the connection. If you are curious about the details, I described it in detail here: <a href="https://forum.universal-robots.com/t/controlling-a-ur5-cb3-with-ros2-and-ubunut-22-connection-refused/33432" rel="nofollow noreferrer">https://forum.universal-robots.com/t/controlling-a-ur5-cb3-with-ros2-and-ubunut-22-connection-refused/33432</a></p>
<p><strong>Current problem:</strong>
In order to further understand where the problem is, I connected my control-computer to an unrelated Laptop, that also runs Ubuntu 22. I used static IPv4 adresses and predefined ports (12345 and 4444), since my original problem requires me to use this way of communication.
I wanted to understand if I can connect the two computer and transfer a file. I used netcat and <a href="https://www.digitalocean.com/community/tutorials/how-to-use-netcat-to-establish-and-test-tcp-and-udp-connections#how-to-send-files-through-netcat" rel="nofollow noreferrer">this</a> tutorial
but I could not transfer a file via the connection. Using the wifi Router with automatic settings works though. I turned off the firewall using:</p>
<blockquote>
<p>$ sudo ufw disable</p>
</blockquote>
<p>The pinging of the IPs (192.168.1.101 and 192.168.1.103) using</p>
<blockquote>
<p>jann@xps13:~$ ping 192.168.1.101</p>
</blockquote>
<p>yields:</p>
<blockquote>
<p>PING 192.168.1.101 (192.168.1.101) 56(84) bytes of data. 64 bytes from 192.168.1.101: icmp_seq=1 ttl=64 time=3.03 ms 64 bytes from 192.168.1.101: icmp_seq=2 ttl=64 time=1.75 ms 64 bytes from 192.168.1.101: icmp_seq=3 ttl=64 time=1.60 ms</p>
</blockquote>
<p>This makes me think that the physical connection works, but there must be some kind of software problem related to the static IPv4 that I don't understand. I did my best to look for possible solutions online, but I am not exactly a network guy, I might have missed something.</p>
<p>When I scan the network from my laptop with netcat I get the following result:</p>
<blockquote>
<p>jann@xps13:~$ netcat -z -n -v 192.168.1.101 50001-50009</p>
<p>netcat: connect to 192.168.1.101 port 50001 (tcp) failed: Connection

</blockquote>
<p>Do you guys have any idea how I could approach the next steps of troubleshooting?</p>

The moment I roll back to kernel 5.15 on the host the latency issues are gone. Even when I restart the VM while still on kernel 6.* as you can see on the graph below issues are gone but only for a short period. Tried installing the latest Ubuntu 23.10(kernel 6.5.0-25-generic) assuming the problem is between newer kernel 6+ and older libvirt inside Ubuntu 22.04lts, but the issue is the same. At the same time when VM has a problem with latency, host latency is good. Also, I created a VM with 1CPU and 1GB on the same host and it works good all the time, no latency issues at all. Tried NUMA CPU pinning, but the problem remains the same. Something is wrong with 6+ kernels, any help would be appreciated. All the sorts of hardware options have already been tried, 100% not hardware-related. I found that when latency issues start we have this on the vnet0 of the VM</p>

I want to copy some files, repos, code, documents etc that I have in my ubuntu machine</p>
<p>In the past, I vaguely remember that sometimes I have had problems copying files to an external device, due to perhaps permissions, etc.</p>
<p>I suspect this is due to the filesystem of the devices I used.</p>
<p>I use a lot of containers too and sometimes these files are created inside the containers therfore the owner is not the same as the outside user</p>
<p>So what is a good way to ensure that I can copy my files without problem to an external SSD?</p>
<p>I believe that perhaps I have to format the disk first? (perhaps to ext4?)
(as commercial products, these devices have a label that says are only "assured to work in windows and mac")</p>

1508737 | 1 | null | 2024-03-27T10:56:48.920 | -1 | 21 | <p>Hello I am having issue sending mail from my own hosted mail server. I has worked fine for a long time.
A few days ago I added DKIM using an online guide, everything seemed fine at first.
About 18 hours later a problem arose where my system cannot send any mail out at all, all incoming mail is OK, outgoing mail sits in the queue and never gets delivered.
I have backed out all the changes for the DKIM (including removing the DNS entry) and waited two days for the changes to work their way around, the problem still exists.
Diagnostics and testing has come up with the following…</p>
<p>Testing with telnet as follows:</p>
<p>Local, testing works ok: <code>telnet 127.0.0.1 25</code> - I can see the connection in my postfix log</p>
<p>Testing to any remote mail system I get the following:</p>
<pre><code>:> telnet alt4.gmail-smtp-in.l.google.com 25
Trying 74.125.200.26...
Connected to alt4.gmail-smtp-in.l.google.com.
Escape character is '^]'.
ehlo googlemail.com
</code></pre>
<p>After this it does nothing at all until it times out or I break with <code>^]</code>
Typing anything here achieves nothing. (typed characters are not shown)</p>
<p>As a comparison, from another system the same test....</p>
<pre><code>:> telnet alt4.gmail-smtp-in.l.google.com 25

</code></pre>
<p>I did telnet testing from my mail server to another system I have available…
Using telnet on the mail server and listening on the port with <code>nc -l -p</code> on the other server, I can create a <code>telnet</code> connection and see the characters I type on the other system</p>
<p>Mail server: <code>telnet <ip of test computer> 55</code></p>
<p>Test computer: <code>nc -l -p 55</code></p>
<p>This connected fine and when I type in telnet the characters appear on the test computer – I first did this test in on port 55 to prove the tactic, when trying exactly the same test on port 25 –it does not work.</p>
<p>The odd thing is, if I telnet to port 25 without first starting the listen on the test computer, the telnet does not connect so it can see there is nothing listening on the port, when it I am listening on the port it does connect, but then cannot send any data.
I have tried disabling my firewalls, stopping and clearing fail2ban and clearing my iptables, (with numerous reboots) none of these have helped.</p>
<p>Something seems to be interfering or blocking outbound traffic on port 25, but I can’t find it and have no idea why it has suddenly started happening.</p>

1508740 | 1 | null | 2024-03-27T11:15:38.030 | 0 | 49 | <p>Just wondering what programming languages I can install straight from the APT that come with built in graphics functions on Ubuntu. I know Java can but I don't know of anything else and information on this is a bit scarce. Can C in GCC produce graphics? Python? Fortran? As far as I know this requires interfacing with APIs which from what I can gather are designed to easily interact with the languages, but I'm not sure.</p>
<p>I am interested in creating games and simulations, and maybe experimenting with Doom style 3d graphics eventually.</p>
<p>Does anyone have more information on this topic? If it's capable of producing graphics at all without modification that's enough for me, but features that simplify this are definitely desirable.</p>

It was completely unexpected because it was working fine up until now, and when it started failing I was in an online meeting. It's also peculiar because it sometimes starts working perfectly (ping 8.8.8.8 has a 0% packet loss with <15ms), other times it just goes very slowly (ping 8.8.8.8 has a 20% - 70% packet loss, with >110ms), and other times there's no connection at all (ping 8.8.8.8 has a 100% packet loss, or >3000ms).</p>
<p><img src="https://i.stack.imgur.com/NuGcE.jpg" alt="ping test on my computer" /></p>
<p>The weird thing is:</p>
<ul>
<li>I have another laptop with Ubuntu 22.10 where my internet connection was fine (ping 8.8.8.8 consistently has a 0% packet loss with < 15ms). So it seems to be a problem with my computer.</li>
<li>It works completely fine when connecting to my Android hotspot instead of my WiFi. So it seems to be a problem with my WiFi??</li>
</ul>
<p>Things that don't work:</p>
<ul>
<li>Restarting the computer.</li>
<li>Restarting the NetworkManager service.</li>
<li>Restarting the router.</li>
</ul>
<p>Does anyone have any idea of what is happening??</p>

<h3>Behavior:</h3>
<p>They crash immediately upon opening (when the default home path is opened).
However, I can use other paths. For example, <code>nautilus ~/Application</code> works.
I can also use <code>sudo nautilus</code>.</p>
<p>When I execute the command <code>nautilus</code>, the terminal outputs <code>Segmentation fault</code>.
When I try to search something in home path (opened in other paths), it crashes.
Additionally, when certain software tries to open Nautilus (such as when importing a config file), it crashes.</p>
<h3>Attempts:</h3>
<p>I tried changing the default file explorer. The main command I used was <code>xdg-mime default nemo.desktop inode/directory application/x-gnome-saved-search</code>. However, it didn't solve the problem.</p>
<p>Then I attempted to debug the core file using <code>gdb</code>, even though it was my first time using it.
I searched and found some commands to dump the core file. After many hours of testing, I finally managed to use <code>gdb</code> with the core file.</p>
<pre class="lang-bash prettyprint-override"><code>ulimit -c unlimited
sudo bash -c 'echo "1" > /proc/sys/kernel/core_uses_pid'
sudo bash -c 'echo ~/coredump/core.%e.%p.%t > /proc/sys/kernel/core_pattern'

In system settings under <code>program settings</code> where there are notification settings for e.g. Thunderbird and other programs I can't even find Brave Browser in the list. Only an entry with <code>other applications</code> where I should be able to disable the notifications for all other programs which I don't want!
Frankly even that setting doesn't get rid of the system pop-up...</p>

According to a thread in reddit, this is a Firefox bug that should have been already fixed for the next release of Firefox: <a href="https://www.reddit.com/r/linuxquestions/comments/1bkitla/keyboard_key_repeat_not_working_only_in_firefox/" rel="nofollow noreferrer">https://www.reddit.com/r/linuxquestions/comments/1bkitla/keyboard_key_repeat_not_working_only_in_firefox/</a>

As usual the directory is owned by the www-data user. After a restart of my docker containers, there were permitted to write to the corresponding directories. To fix this I tried to change the directory permissions as the root user of the server.
The directories have the following permissions:</p>
<pre><code>drwxrwxr-x 1 www-data www-data 49 Jan 25 2020 app
drwxr-xr-x 1 www-data www-data 19 Jan 25 2021 db
drwxr-xr-x 1 www-data www-data 20 May 18 2020 docker
</code></pre>
<p>When I run <code>chown root:root -R app</code> the server produces the following output:</p>
<pre><code>chown: cannot read directory 'app/data': Permission denied
chown: cannot read directory 'app/custom_apps': Permission denied
chown: changing ownership of 'app/themes/example/core/css/server.css': Operation not permitted
</code></pre>
<p><em>(shortened it slighly... the pattern repeats for every sub directory)</em></p>
<p>Already tried to run it as the www-data user, which doesn't work and also running the commands inside the docker container aren't working.</p>
<p>My <code>/etc/fstab</code>:</p>
<p><code>XXXXXXX:/mnt/user/directory /home/user/cloud/ nfs defaults,acl 0 0</code></p>

Then I tried some solutions, first I did <code>sudo evtest</code> and the result is as follows:</p>
<p><a href="https://i.stack.imgur.com/Zq19J.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/Zq19J.png" alt="evtest" /></a></p>
<p>And I tried:</p>
<pre class="lang-none prettyprint-override"><code>sudo apt update
sudo apt install xserver-xorg-input-synaptics
sudo apt update
sudo apt purge --auto-remove xserver-xorg-input-all && sudo apt install xserver-xorg-input-all
</code></pre>
<p>And I tried another solution after that.</p>
<pre><code>cat /sys/class/dmi/id/chassis_type
</code></pre>
<p>When I type it into the console, I get "10".</p>
<p>And I tried:</p>
<pre><code>sudoedit /etc/modprobe.d/blacklist.conf
</code></pre>
<p>I added a line to the file:</p>
<pre><code># bug in module breaks keyboard, so don't load it
blacklist intel_vbtn
</code></pre>
<p>I saved it and rebooted, but it didn't work. I'm typing all this on a USB keyboard. My USB keyboard works.</p>

<p>Everything runs OK, but the CPU frequency appears very high, even when idle. It never drops below <strong>Freq: 56%</strong> and frequently scales to 116% while browsing Instagram or watching YouTube videos.</p>
<p>I installed <code>cpupower-gui</code>. By default the governor is <code>schedutil</code>. When I set it to <code>powersave</code>, the CPU frequency remains at 56% and overall performance gets slower.</p>
<p>For some reason, when I run the command:</p>
<pre><code>cd /sys/devices/system/cpu/cpu0/cpufreq && paste <(ls *) <(cat *)

<p>some lines get shifted, please see below.</p>

<li>After the initial scan after install, on day 1, it took 1 minute.</li>

Multipathing is enabled. When we issue the multipath -ll, i am seeing only 2 paths rather it should be 4 paths. As per initial troubleshooting with netapp storage team, it seems the paths shown in multipath -ll are coming from NIC1, the other NIC2 paths are not visible. iscsiadm discovery have sessions established with both NIC's. Right now while we have done NIC failure testing from both server or storage side, we have not seen any packet drops and so storage team says this is OS issue. Also, our Solution architect believes that this is not the correct design having NIC's serving the traffic individually.</p>
<ol>
<li><p>Our objective is to achieve the data/iscsi traffic to be served by both the NIC's so that highly sensitive apps/dbs hosted on the server will not have any downtime for any sort of failures in storage or server side. I believe i am missing something on the multipath configuration.</p>
</li>
<li><p>We also thought of having LACP with layer2, so that i can have both NIC's actively serving the traffic, but i am unsure if this is the best practice of enabling LACP with ISCSI or not.</p>
</li>

<p>Please advise.</p>

<p>Update: I tried using the Ubuntu Live Installation USB but it did not seem to work. Next, I tried recovery mode, then choose 'root', then in the root terminal, I uninstalled virtualbox using 'sudo apt-get remove virtualbox'. I also noticed some output about no space left on device (in /usr/man/db I think), so I went to Downloads folder and deleted everything, which freed 1GB. However now the screen shows as follows.</p>

<p>Environment:</p>
<pre><code>Dunst version: 1.5.0
OS: Ubuntu 22.04
Window Manager: x11+i3
Compositor (if any): picom

<p>The progress bar doesn't appear in my notifications with the command in the offical documentation</p>

<p>Here's a bit of log :</p>
<pre><code>appname: 'dunstify'
summary: 'Wotking ...'
...
progress: 42
</code></pre>
<p>Troubleshooting Steps Taken:</p>
<p>Verified that my Dunst version (1.5.0) supports progress bars.(Which seems to be the case)</p>
<p>Checked and updated my dunstrc configuration with progress bar settings, including color and width.</p>
<p>Restarted Dunst and even the system multiple times after making</p>
<p>Tested with different notification hints and minimal</p>
<p>Temporarily disabled my compositor (Picom) to rule out any interference.</p>
<p>Ran Dunst with verbosity debug to look for any relevant errors or warnings but didn't find any clues related to the progress bar issue.</p>
<p>Despite these steps, the progress bars still aren't displaying. The rest of the notification appears as expected, and I haven't encountered other issues with Dunst.</p>
<p>Has anyone else encountered this issue or have any suggestions on what else I might try to resolve it? I'm open to any ideas, whether it's a configuration tweak, a different approach to debugging, or any insights if you've faced and resolved a similar issue.</p>
<p>Thank you in advance for any help or guidance you can provide!</p>

<p>Meanwhile, Thunderbird updated to 115.9</p>
<p>I'm out of ideas but urgently need my calendar data. Is anybody has any idea?
Or, we can bypass Thunderbird if you know how to get back calendar data from saved Thunderbird profile (default.zip).

<p><code>#!/usr/bin/env python</code></p>
<p>This resolved the issue. However, there are numerous scripts bundled with DOCK3.7 that exhibit this header problem. I'm curious if there's a more efficient method to correct this, rather than manually fixing each script's header. Any insights or suggestions would be greatly appreciated. Thank you!</p>

When I open a youtube video, the video stops and starts loading, at the same time the audio goes crazy, it loops the first seconds of the video. Similar thing happens with spotify.

<p>Edit: For now reinstalling alsa after update solved the problem, like here: <a href="https://askubuntu.com/questions/722685/realtek-audio-drivers-for-ubuntu">Realtek Audio Drivers for Ubuntu</a></p>

Our sensor side is developed using C and lwIP, while the server side is developed in Python. We conducted tests on both Windows and Linux. On the Windows version, we were able to achieve stable data transfer for 20 minutes. However, on the Ubuntu server, the server failed after receiving a couple of packets from the first frame. It appears that the server’s TCP configuration needs to be adjusted. Could you please advise on how to proceed with this configuration adjustment?</p>

I could then insert e.g. an EQ or limiter into the signal chain between the desktop apps and my laptop speakers. This was especially useful when the audio in a browser was too quiet even with the laptop volume at full volume. (So one uses the EQ to cut out frequency content that won't be reproduced by the laptop speakers, and then limit the result to make things louder.)</p>

</code></pre>
<p>And here is the problem I had before setting <code>pcie_aspm=off</code> and <code>pci=noaer</code> in the <code>GRUB_CMDLINE_LINUX_DEFAULT</code> line in <code>/etc/default/grub</code></p>
<pre><code>what is happening here?

<p>What do I do? I really don't wanna switch to Arch Linux again (for obvious reasons) so can anybody suggest a fix? I am on Ubuntu 23.10 at the moment and the rtl8821ce-dkms package is unavailable and i have installed the rtl8821ce-dkms driver from <a href="https://github.com/tomaspinho/rtl8821ce" rel="nofollow noreferrer">https://github.com/tomaspinho/rtl8821ce</a> but I'm still encountering errors. Any help would be appreciated.</p>

I am experiencing this weird issue where ubuntu freezes if I move the audio volume slider, it kinda <strong>lags</strong> and sometimes <strong>freezes</strong>.
This happened on <strong>Spotify</strong> as well as <strong>Rhythmbox</strong>.</p>
<p>Initially I thought this is because of Nvidia not being fully supported by linux so I uninstalled all nvidia drivers.</p>
<p>for the command <code>lspci | grep -i audio</code>
The output is:</p>
<blockquote>

<p>I also have <em><strong>WhiteSur-gtk-theme</strong></em> installed if this information helps.</p>

</blockquote>
<p><strong>Firefox</strong> lags sometimes as well.
Please help me solve this issue as I am not able to normally use my laptop at all despite my laptop being so powerful.</p>
<p>Some fixes I tried but didn't work:</p>
<ol>
<li>switched to flatpak from snap</li>
<li>Uninstalled Nvidia drivers</li>

want to preserve bootability you also need to change the UUID
accordingly elsewhere, for example, with EFI/UEFI booting, in
<code>/boot/efi/EFI/ubuntu/grub.cfg</code> and <code>/etc/fstab</code>.</p>
</blockquote>
<p>Also, "Vojtech Trefny" documents how it is possible to boot to GRUB from the computer's BIOS boot menu in his answer to the question, "<a href="https://askubuntu.com/questions/16042/how-to-get-to-the-grub-menu-at-boot-time">How to get to the GRUB menu at boot-time?</a>"</p>
<blockquote>
<p>Menu will appear if you press and hold <kbd>Shift</kbd> during loading
Grub, if you boot using BIOS. When your system boots using UEFI, press
<kbd>Esc</kbd>.</p>
<p>For permanent change you'll need to edit your <code>/etc/default/grub</code>
file:</p>
<p>Place a <code>#</code> symbol at the start of line <code>GRUB_HIDDEN_TIMEOUT=0</code> to
comment it out. If that line doesn't exist, then you can comment out
this line instead: <code># GRUB_TIMEOUT_STYLE=hidden</code>, and then change
<code>GRUB_TIMEOUT=0</code> to <code>GRUB_TIMEOUT=5</code>, for instance, to give the grub
menu a 5 second timeout before it automatically logs you in.</p>
<p>Save changes and run <code>sudo update-grub</code> to apply changes.</p>

<p>Is the answer to the question "<a href="https://askubuntu.com/questions/1140273/how-to-change-uuid-in-the-boot-grub-grub-cfg">How to change UUID in the /boot/grub/grub.cfg</a>" given by "Pierre ALBARÈDE" the best approach? There are a number of options in that article, and I am still a little confused as to what the best approach from there or from somewhere else is. Still. when I issue the command "sudo blkid" to get the UUID's for all the disks on the system, I get an entry for the EFI (boot) partition sdc5 as:</p>
<blockquote>
<p>sudo blkid</p>
</blockquote>
<blockquote>
<p>/dev/sdc5: UUID="1887-E4A1" BLOCK_SIZE="512" TYPE="vfat" PARTUUID="d05239a5-e32f-4d3c-bc80-76bca4afb0b8"</p>
</blockquote>
<p>There is the UUID and there is the Part UUID. Which UUID needs to be added to the GRUB menu? (I guess that I could inspect the menu of the source disk that I am duplicating to figure this out, but I am hoping that this part of the question can also be addressed in the answer.)</p>
<ol>
<li>The etc/defualt/grub file can be modified to allow a choice of boot options and "e" can be used to successfully boot to Ubuntu form the disk:</li>
</ol>
<pre><code># If you change this file, run 'update-grub' afterwards to update

<p>After that, the answer to the question "<a href="https://askubuntu.com/questions/1140273/how-to-change-uuid-in-the-boot-grub-grub-cfg">How to change UUID in the /boot/grub/grub.cfg</a>" given by "Pierre ALBARÈDE" can be used to update the UUID's in:
Directly change the UUID's in <strong>/boot/grub/grub.cfg</strong> (since <strong>/boot/grub/grub.cfg</strong> is not updated automatically), and also in <strong>/boot/efi/EFI/ubuntu/grub.cfg</strong> and also in <strong>/etc/fstab</strong>. Then run <strong>sudo update-grub</strong>.</p>
<p>Am I missing something in the steps needed to update the files that <strong>sudo update-grub</strong> does not update and then run <strong>sudo update-grub</strong> once booted into the new disk.</p>
<p><em>What is the best approach, so that the new cloned disk can boot, just like the old one, with the proper UUID's in each of the respective's configuration files?</em></p>

<p>I have a brand new Xgimi projector with Android TV on it. The sound is good, so I want to use it as audio over bluetooth for various devices.</p>
<p>It works fine from any Android phone or tablet.</p>
<p>But from 3 different Kubuntu PCs (1yo, 11yo and 3yo, all up to date 23.10), the audio disconnects after 30s (Bluetooth stays connected though). The same PCs have to problem connecting to various BT headphones I've tested.</p>
<p>So the problem is purely from KDE/Linux to Android TV. When starting music over BT, the projector starts an app (?) called XMusic player. After 30s the profile disappears from the PulseAudio volume control while the BT connection is still present (on both ends).</p>
<p>dmesg doesn't show anything besides <code>input: gjs projo (AVRCP) as /devices/virtual/input/input58</code> upon connection.</p>
<p><code>/var/log/syslog</code> has the following (simplified):</p>

<p>How can I troubleshoot this issue further?
Are there any additional drivers or configurations required to make the camera work?
What does the "UVC non-compliance" warning mean, and how can I address it?</p>
<p>Thanks for your answers and suggestions</p>

1508852 | 1 | null | 2024-03-28T11:28:10.477 | 0 | 13 | <p>I'm new to Linux and Ubuntu. I'm attempting to get PCI and PCIe Sound Cards to be recognized by ALSA and nothing I've tried has solved the problem. I've attempted to get two different sound cards (Digigram VX222v2 and Digigram VX222e) to work on Ubuntu 24.04.4. I've identified that both of these sound cards utilize the snd-pcxhr ALSA driver. Entering a modinfo snd-pcxhr in terminal returns information, indicating that the driver is present in the kernel. The user is included in the Audio group, so I don't think it's a permissions issue. I'm certain that I'm missing a step but I've been unable to find any information online that leads to these sound cards being recognized by the system. Can someone please point me in the right direction?</p>

1508858 | 1 | null | 2024-03-28T11:55:05.793 | 0 | 24 | <p>So a few months back I was using my Toshiba 1Tb external HDD and when I was done I unmounted it before taking 'Safely Remove Drive'. Not thirty minutes later when I went to reconnect it, it wouldn't read. I connected it to my windows machine (which has since crashed) and it tried to run chkdsk but there was no drive letter assigned to it. In diskpart, it was visible but any action I tried to take such as assigning it a letter all failed.
I tried a variety of options which probably worsened the solution including using TestDisk and Disk Drill in attempts to fix what I thought were bad sectors but a power outage prevented both from completing. Now the Drive still appears when I run lsblk on Ubuntu but it shows it has no partition. It doesn't even show up on Diskpart anymore. What can I do to fix this without losing everything on the Drive?</p>
<p>NOTE: At some point when I went to Disk Management (before the power outage), it told me to initialize the disk and displayed all of it's space as unallocated but I knew if I initialized it then I would lose everything so I didn't but not that option doesn't even come up because the disk doesn't even appear in disk management when I connected it to a friend's Windows.</p>
<p>PLEASE HELP. I would really love any and all feedback on those who might've faced similar issues.</p>

1508859 | 1 | null | 2024-03-28T12:30:05.930 | 0 | 43 | <p>Sorry for my english. I created an application. I would like to package it in snap format. I do it. Unfortunately, when I start the application (after I installed it on a PC with newly installed Ubuntu 22.04, I obviously use a virtual machine to test) it does not look for the libraries in the snap folder but in the operating system. Obviously on the PC where I created the app it works but on a newly installed system it cannot start. Since snaps like flatpaks give the possibility to install an application with all dependencies included, I would like the program to take the libraries that I put inside the snap (which are the ones the program needs to run). The snapcraft.yaml file is configured like this:</p>
<pre><code>name: lamiavideoteca
base: core22
version: "2.40"
summary: Program for cataloging Films description: Program that allows you to catalog your collection of Films and/or Video/Audio.
grade: stable
confinement: strict
parts:
lamiavideoteca:
plugin: dump
source: .
apps:
lamiavideoteca:
command: usr/bin/LaMiaVideoteca
desktop: usr/share/applications LaMiaVideoteca.desktop
environment:
QT_PLUGIN_PATH: $SNAP/usr/lib/$SNAPCRAFT_ARCH_TRIPLET/qt6/plugins:$QT_PLUGIN_PATH
LD_LIBRARY_PATH: $LD_LIBRARY_PATH:$SNAP/usr/lib/$SNAPCRAFT_ARCH_TRIPLET
</code></pre>
<p>As you can see from the code I set the environment variables to show the libraries to the application. The package is generated but when I start it from the terminal I notice that it does not find the necessary libraries, which are present in the /snap/lamiavideoteca/current/usr/lib folder.</p>
<p>I tryed change librery location on snap. I change snapcraft.yaml (I used stage... stage-packages) but nothing works and the programs search the library on usr/lib and not on snap/lamiavideoteca/usr/lib. Why? Thanks for the answer</p>

1508863 | 1 | null | 2024-03-28T13:26:07.010 | 1 | 59 | <p><em>Background:</em>
I have 1 room setup with desktop pc with single GPU, two monitors and tv connected with long hdmi cable in same room.</p>
<p>What I want to do is use two monitors on desk for web browsing / working / gaming and dedicate tv for steam big-screen. There is no real obstacle moving big-screen to windowed mode, drag it to tv, make it full size again - every - single - time.</p>
<p>Real obstacle comes with games with no option to go windowed mode or choose monitor when they seem more or less pop on random screen or something between. This is rubbish.</p>
<p>Issue could be easily resolved with single gpu - multi seat setup, where TV have dedicated X session, account, steam, (autologin) and dedicated usb ports for controllers.</p>
<p><em>History:</em>
I can see this was well supported some time ago with example lightdm with multiseat manager and all.</p>
<p><em>Current state:</em>
all we have is unofficial, outdated manuals and videos presenting multi seat in action but after trying to accomplish multi-seat with ubuntu, lubuntu and popos for 3 days without any success, I feel totally helpless.</p>
<p>I really don't want to revert back to windows and buy 100$ russian-software.
Having decent multi-seat manager for Ubuntu would be a huge advantage and bring more windoze users to ubuntu community as similar setups been trending for some time now.</p>
<p>Q: Does anyone have validated manual / instructions to offer for setting up multiseat for Ubuntu 23.10?</p>
