2053 | 1 | 2055 | 2010-08-12T16:19:57.170 | 15 | 1910 | <p>I've just bought a game (Machinarium) which does not come with a deb file neither is it a ./configure, make etc type of application. I can just run it. Where is the best place to put it so i can create a launcher and keep it out of my home directory? </p>
<p>i.e. I'm basically asking where are applications are installed and should i put this game there.</p>
<p>Thanks!</p>

I've tried to make a launcher which points towards this executable which runs fine when i click on it. When i try and run it from the launcher the player comes up (black screen) and i can right click and get the flash options however the game does not load.</p>
<p>Any ideas?

2071 | 1 | 4973 | 2010-08-12T18:12:21.070 | 2 | 1811 | <p>I am running UNR (but using the regular gnome launcher) and have DropBox installed. Since I use my laptop on the train, there is no network connectivity. However once I reconnect to a network, dropbox seems to be completely unresponsive to the fact that there is a network connection and has to be restarted (which means lots of hard drive scanning, battery usage, slowdowns, etc). Is there a way to get dropbox to reconnect automatically, or gota wait for a patch?</p>
<p><strong>Edit</strong>:</p>
<p>Nothing special about my network configuration, pretty much out-of-the-box. Note that most of the time I connect to wifi not cable. But the problem does not change in either case.</p>
<p>And I forgot to mention, I usually put my computer to sleep/hibernate in between leaving home and using it on the train so it "loses" or "gains" connection on waking up.</p>
<p><strong>More Edit</strong>:</p>
<p>I just had the problem happening again. Basically it has a network cable plugged in. Goes to sleep. On wakeup (cable still plugged in) dropbox is stuck at "connecting".</p>

Very quickly it gets into 100% cpu use (thank god I have multiple cores) and hundreds of megs of ram. Even closing tabs does not help the issue (unless google.com uses supreme amounts of javascript).</p>
<p>On the same machine chromium browser runs lightning smooth. I tried swiftfox, nothing useful there. Is this a common problem? Only recent (past 3.6) versions have even been able to scroll rather smoothly vs choppy performance when using the scroll bar on pages. The performance is getting close to running firefox on a windows xp virtual box vm.</p>

<p>Kubuntu 9.10. Installed Gnome packages for Ubuntu and use those. Upgraded to 10.04.</p>

<pre><code>root@tatooine:~# /etc/init.d/mysql status
Rather than invoking init scripts through /etc/init.d, use the service(8)
utility, e.g. service mysql status
Since the script you are attempting to invoke has been converted to an
Upstart job, you may also use the status(8) utility, e.g. status mysql
mysql start/running, process 14048
</code></pre>
<p>This seems to have been brought about in the latest LTS of Ubuntu - why? What's so bad about <code>/etc/init.d/</code> and what/is there a difference between <code>service</code> and <code>/etc/init.d/</code>?</p>

(Of course, reads can cause the disk to spin up; you'll want to get into the habit of running <code>cat /files/I/m/likely/to/need >/dev/null</code> before the disk spins down.) In order for noflushd to be effective, turn off all swap and mount your filesystems with something like <code>commit=3600</code>.</p>\n<p>Using noflushd effectively means that your data can remain unwritten to disk for an extended length of time. This is a risk, to be weighed against the benefit of not having any noise or heat coming from the disk for a while. Don't use noflushd if you're not comfortable with that risk.</p>\n</li>\n</ul>\n",

<pre><code>cesar@minas-tirith:~$ ls /media/

<p>As you can see, the <code>disk</code> entry is repeated with additional <code>_</code> appended at the end. I don't know why this happens, but I can imagine that under some circumstances, the system can't mount the disk in <code>/media/disk/</code> and creates <code>disk_</code>, then it can't mount it in <code>/media/disk_</code> and creates <code>disk__</code> and so forth. The other entry <code>0BC7-569E</code> I think it's from a SD media card so it's not only for USB drives.</p>

<pre><code>me@work: ssh -YR 4317:localhost:4317 me@home
</code></pre>
<p>At this point I can run rhythmbox from the ssh session with X11 forwarding, and I assumed rhythmbox would be transparently talking to pulseaudio over the reverse tunnel, resulting in the music playing on my work machine. However instead it appears that the music still plays on my home computer. I've tried messing around with PULSE_SERVER as well to no avail.</p>
<p>Has anyone accomplished something similar? It seems like this should be relatively simple due to pulseaudio's design. I've played around with mounting my music library via sshfs instead but I'd really like to have one set of metadata/app settings/playlists and such. Thanks for any tips!</p>

2146 | 1 | 2149 | 2010-08-13T07:55:37.973 | 5 | 6933 | <p>I need to boot Ubuntu in a computer (computer A) with no CD. I have a 16 Gb pendrive with a live Ubuntu version. The pendrive works in at least two newer computers. Computer A boots from a 2Gb pendrive right. So it's likely a BIOS issue.</p>
<p>But it's quite inconvenient to always carry two pendrives, how can I made the older computer boot from the bigger drive?.</p>
<p>Notes:</p>
<ul>
<li>Repartitioning the drive doesn't seen to work.</li>
<li>I noticed than the 16 Gb pendrive is seen like a external zip drive by the BIOS, while the smaller one is seen as a Hard Disk. Likely related.</li>
</ul>

2150 | 1 | 2176 | 2010-08-13T08:44:00.683 | 7 | 342 | <p>The system is a spare Dell 2400 I wiped clean, with Ubuntu 10.4 installed. Update manager has everything current, and I haven't been mucking with drivers or tricky system settings. In fact, it has been a stable and friendly system to install and use.</p>
<p>So imagine my surprise when browsing to <a href="http://element-14.com/" rel="nofollow">http://element-14.com/</a> (an otherwise useful community site for electronic engineering types) followed a redirect or two, then black screen, then the I'm starting up tune with the pink hazy smoke and nothing further works. The keyboard is crashed hard, and the <kbd>Alt</kbd>-<kbd>SysRq</kbd> key combos do nothing.</p>
<p>More than just firefox and the X server are crashing. I repeated the crash with an SSH session open, and not only did the connection get taken down, but it no longer responded to attempts to get a fresh connection.</p>
<p>I tried enabling Apport, in hopes that it would notice something and help identify the culprit, but it seems to be oblivious to the crash.</p>
<p>Each time, I've had to lean on the power button to reboot.</p>
<p>Google searches hint that there are issues with the particular intel chipset providing the VGA on its motherboard.</p>
<p>I'm looking for advice about how to proceed with debugging this kind of crash. Any ideas?</p>
<p><strong>Update:</strong> I tried following advice to try setting up the <code>netconsole</code> kernel module and a matching netcat instance to receive the log. I set up netcat on my XP box, used <kbd>Alt</kbd>-<kbd>SysRq</kbd>-<kbd>S</kbd> to verify it could receive kernel messages, then browsed to the site. Only two <code>printk()</code>s were logged:</p>
<pre>
[251728.009794] i915: Unknown parameter `modset'
[251728.051420] i915: Unknown parameter `modset'
</pre>
<p>Hmm. Perhaps my video driver is misconfigured? Especially since I see these same messages in the output of <code>dmesg</code> just after booting.</p>
<p>At least this time I explicitly synced my disks <em>before</em> deliberately crashing the system.</p>
<p>For the record, <code>lspci -nn | grep VGA</code> says:</p>
<pre>
00:02.0 VGA compatible controller [0300]: Intel Corporation 82845G/GL[Brookdale-G]/GE Chipset Integrated Graphics Device [8086:2562] (rev 01)
</pre>
<p><strong>Update: Solved!!!</strong></p>
<p>The hint to use <code>netconsole</code> led to an epiphany. Googling around the phrase "i915 unknown parameter modset" suddenly led me to trip over the root cause.</p>
<p>The name of the option to the i915 driver is <strong>modeset</strong> not <strong>modset</strong>.</p>
<p>I changed /etc/modprobe.d/i915.conf to have the correct spelling, rebooted, and now I can access element-14 (and presumably other sites that do whatever it is that element-14 does that triggers the bug in the video driver) without an unpleasant forced reboot.</p>
<p>This leaves behind the (apparently well known) issue that the i915 driver lacks quality, especially on older chipsets. Apparently the Kernel Mode Setting feature is particularly deficient. Without the option spelled correctly, it defaulted to KMS enabled, and also crashed. With it spelled correctly, KMS is disabled, and the driver survives whatever content was triggering the crash.</p>
<p>Also, there are a number of bug pages at launchpad and other community sites that have the wrong spelling of the option name. I strongly suspect that is where I got the spelling I used.</p>
<p><strong>Edit:</strong> I've copied the relevant solution to an actual answer, and improved my description of it here.</p>

Inspired by this <a href="https://askubuntu.com/q/2099">question</a> I realized that some default settings may be rather conservative on Ubuntu and that it's possible to tweak it with little or no risk if you wish to make it faster.</p>
<p>This is not meant to be application specific (e.g. make firefox load pages faster), but system wide.</p>
<p>Preferably 1 tip per answer, with enough detail for people to implement it.</p>
<p>A couple of mine would be:</p>
<ul>
<li>Install <a href="http://techthrob.com/2009/03/02/drastically-speed-up-your-linux-system-with-preload/" rel="noreferrer">Preload</a> (via Software Center or <code>sudo apt-get install preload</code>);</li>
<li>Change <a href="https://help.ubuntu.com/community/SwapFaq" rel="noreferrer">Swappiness</a> value - "which controls the degree to which the kernel prefers to swap when it tries to free memory";</li>
</ul>
<p>What are yours?</p>
<p>PS: Since this is not intended to have a unique answer but rather, several useful tips, I'm making this community wiki out-of-the-box.</p>

2261 | 1 | 209877 | 2010-08-14T11:43:20.460 | 65 | 85091 | <p>What is the Ubuntu way for system administrators to receive system notifications, which typically take the form of e-mail sent to the root account?</p>
<p>Examples of such notifications are the output of cron jobs, or <a href="https://superuser.com/questions/175686/automatic-notification-of-degraded-raid-array-in-ubuntu">degraded RAID notifications</a>.</p>
<p>On a pretty much default Ubuntu 10.04 installation, I can't find any way that anything happens to root's mail other than being deposited in <code>/var/mail/root</code>. How are users supposed to 1. discover it and 2. read it as it arrives?</p>
<p>I observe that on a warty, the installer added <code>root: myusername</code> to <code>/etc/aliases</code>. So back then the user who installed the system if (s)he read the local mail. So there seems to have been a regression somewhere along the way. Still this was not a complete solution, because Ubuntu users can't be expected to be aware that they have local mail and should set up their mail client to read it.</p>
<p><strong>ADDED</strong>: given current replies, a server user should be able to cope, provided he's aware of the issue. Fair enough. But consider J. Random Desktop User, who doesn't know how to use a command line, and only knows how to click the mailbox icon to read his mail. How can he be notified that his system wants to tell him something? (Allow a one-time intervention by a more competent user if that's unavoidable.)</p>

"body": "<p>Encouraged in the comments by <a href=\"https://askubuntu.com/users/1059/gilles\">Gilles</a>, I have adapted and expanded another answer:</p>\n\n<ul>\n<li><a href=\"https://askubuntu.com/questions/192572/how-read-local-email-in-thunderbird\">How do I read local email in thunderbird?</a> </li>\n</ul>\n\n<p>(I am running Ubuntu 12.04.1 LTS, but the general setup process should apply to previous and future Ubuntus)</p>\n\n<hr>\n\n<p>The first thing to do is to install a Mail Transfer Agent (MTA) so the mail can be relayed to a mail User Agent (MUA) such as <code>Thunderbird</code>. This is only necessary because we are dealing with local mail and want to be able to send and receive it; with normal remote gmail type accounts, only a user agent such as <code>Thunderbird</code> is necessary.</p>\n\n<p>I use <code>postfix</code>, which itself is an alternative to <code>sendmail</code>, of which there are commercial and open source versions. More information about postfix's capabilities is at the <a href=\"http://www.postfix.org/\" rel=\"noreferrer\">official site</a> and users may find that the <a href=\"http://www.postfix.org/lists.html\" rel=\"noreferrer\">mailing lists</a> contain useful information if any issues arise. </p>\n\n<p>So, to install the program, run</p>\n\n<pre><code>sudo apt-get install postfix\n</code></pre>\n\n<p>You can either configure it when it is installed, or decline the offer and later run </p>\n\n<pre><code>sudo dpkg-reconfigure postfix\n</code></pre>\n\n<p>to create the important config file (<code>/etc/postfix/main.cfg</code>). If you ever manually edit this file, which is not necessarily recommended, you must run <code>sudo newaliases</code> and <code>sudo service postfix restart</code> afterwards to apply the changes.</p>\n\n<p><code>Postfix</code> is pretty straightforward to setup, although you may have some particular settings that you wish to apply. In the first screen you see below, you must choose the local option for your mail:</p>\n\n<p><img src=\"https://i.stack.imgur.com/CNWaB.png\" alt=\"enter image description here\"></p>\n\n<p>Then on the next screen choose your 'mail name'; it is usually the same as <code>/etc/hostname</code>. You can accept the defaults for most of the following screens. </p>\n\n<p><img src=\"https://i.stack.imgur.com/zcDDg.png\" alt=\"enter image description here\"></p>\n\n<p>When it mentions <code>/etc/aliases</code> and the <em>Root and Postmaster recipient</em> (as above), you can fill in your user name, but make sure you check your aliases file is as it should be by reading the next section of this tutorial. </p>\n\n<p>First, as also recommended <a href=\"http://ubuntuforums.org/archive/index.php/t-1942687.html\" rel=\"noreferrer\">in this discussion</a>, your <code>/etc/aliases</code> should be like this if it is setup correctly: </p>\n\n<pre><code>postmaster: root\nroot: mike \n</code></pre>\n\n<p>If not, edit it with <code>sudo nano /etc/aliases</code>, and then run <code>sudo newaliases</code> and <code>sudo service postfix restart</code> so that the configuration is updated. <code>Postfix's</code> aliases feature allows mail to be redirected, so the setup is very <strong>important</strong> for the rest of this tutorial.</p>\n\n<p>As also noted in the <a href=\"http://ubuntuforums.org/archive/index.php/t-1942687.html\" rel=\"noreferrer\">above link</a>, you need to create a <code>.forward</code> file containing your username and localhost: e.g. <code>mike@localhost</code> so that root's mail will be forwarded to you. To do this, enter these commands:</p>\n\n<pre><code>sudo touch /root/.forward\n</code></pre>\n\n<p>and then run </p>\n\n<pre><code>sudo nano /root/.forward\n</code></pre>\n\n<p>to place your user: e.g. <code>mike@localhost</code> in the file and save it.</p>\n\n<p><strong>In addition</strong>, I found it was necessary to add your user to the mail group so that <code>Thunderbird</code> could access the mail files:</p>\n\n<pre><code>sudo adduser $USER mail\n</code></pre>\n\n<p>and then logout and login for the changes to take effect. There is no need to <code>chown</code> or <code>chmod</code> any files, as some articles might suggest, and adding your user to the mail group is much better practice and avoids any direct changing of the permissions on the root filesystem.</p>\n\n<hr>\n\n<p>Now for the <code>Thunderbird</code> configuration. Go to edit > account settings > account actions > add other account > select Unix spoolmail and in the next screen put your username in the first box and place <code>yourusername@localhost</code> in the second box.</p>\n\n<p><img src=\"https://i.stack.imgur.com/bM1vn.png\" alt=\"enter image description here\">\n<img src=\"https://i.stack.imgur.com/ObDmF.png\" alt=\"enter image description here\"></p>\n\n<p>Now, go to your new account in account settings and select server settings and select the local directory as <code>/var/mail</code> or <code>/var/mail/username</code> (if setup), as in the screenshot below.</p>\n\n<p><img src=\"https://i.stack.imgur.com/MgY3g.png\" alt=\"enter image description here\"></p>\n\n<p>As per the instructions <a href=\"http://linux.eaton.net.nz/?p=108\" rel=\"noreferrer\">in this article</a> you will need to configure the smtp server if you want to test the account by sending a mail to <code>root@localhost</code> and then clicking get mail in Thunderbird to receive it, as root's mail is being redirected to <code>youruser@localhost</code>. </p>\n\n<p>Go to account settings > outgoing server and choose to add a new one. The settings should be as in the screenshot below:</p>\n\n<p><img src=\"https://i.stack.imgur.com/yho7l.png\" alt=\"enter image description here\"></p>\n\n<p>Now, finally test your account by composing a mail to <code>root@localhost</code> and then a few seconds later clicking get mail on your account. You should see an email like this:</p>\n\n<p><img src=\"https://i.stack.imgur.com/CkL0s.png\" alt=\"enter image description here\"></p>\n\n<p>Some programs or logs will need to be configured so that they send mail to root, but that can be decided as you find the need. This article should hopefully be useful as it is not always straightforward to set up <code>Thunderbird</code> to receive local mail.</p>\n",

2294 | 1 | 2297 | 2010-08-14T21:54:28.820 | 0 | 4038 | <p>I just installed 10.04, and used manual partitioning to preserve my '/home' from a 9.04 install. (To be clear: I did not upgraded 9.04 to 10.04, but installed 10.04 off a of CD, keeping only my '/home'.) After the sucessful 10.04 install, I used synaptic to apply all updates, rebooted, removed some packages (mostly tomboy and bluetooth), rebooted, and then used synaptic to install tonnes of packages, mostly from <code>lucid/main</code> and <code>lucid-updates/main</code>, though I also did install a number from <code>lucid/universe</code> and <code>lucid-updates/universe</code>.</p>
<p>A minute or so after the mass installation of new packages, a red circular icon with a white bar running horizontally through it appeared in my notification area. (The icon is quite like the "Do not enter this road" sign pictured <a href="http://www.mto.gov.on.ca/english/dandv/driver/handbook/section3.1.1.shtml" rel="nofollow">here</a>.) On hovering my mouse over the icon, I get the following message:</p>
<blockquote>
<p>An error occurred, please run Package Manager from the right-click menu or apt-get in a terminal to see what is wrong. The error message was: 'Unknown Error: '' (E:Opening configuration file /etc/apt/apt.conf.d/99synaptic - ifstream::ifstream (13: Permission denied))' This usually means that your installed packages have unmet dependencies</p>
</blockquote>
<p>(Since there was no way to copy the text, I transcribed it; it isn't impossible that it is not a completely faithful transcription.)</p>
<p>I then ran the following commands:</p>
<ol>
<li><code>sudo apt-get check</code></li>
<li><code>sudo apt-get clean</code></li>
<li><code>sudo apt-get autoclean</code></li>
<li><code>sudo apt-get autoremove</code></li>
</ol>
<p>and then ran those same commands (in that order) but also with the <code>-f</code> flag. I then rebooted. This hasn't removed the warning icon from the notification area. So, I am at a loss for how to proceed.</p>
<p>[Snip a lot of detail about what packages I'd installed and removed that turned out not to be relevant at all.]</p>

<p>I want to set up a Ubuntu box with a keyboard and a twitter program, so that everything that is typed into the keyboard is posted on twitter. So what I am looking for is a simple twitter client that will force all input via keyboard into a tweet and post to twitter after 140 chars, after the enter key, and/or a time period. </p>
<p>Basically what I am planning is a little experiment to leave a keyboard somewhere it can be typed on and played with, and post all text entry through to twitter automatically.</p>
<p>The alternative is to simply save all entered text to a file, but I would prefer the twitter approach.</p>
<p>Does anyone have any ideas if there is a program/script out there that will do this for me?</p>
<p>I am mainly looking for a command line script, as GUI programs are easier to exit or lose focus than a command line.</p>

<p>At random times, Ubuntu 10.04 freezes, and I have to do a hard shutdown. It was upgraded from 9.10 which didn't freeze. First, is this is common problem with a quick answer, and if not, what can I do to diagnose it? I've tried checking application/kernel logs, but nothing gives me a clue as to what caused the problem. My guess, is that since the OS froze, no logs could be updated.</p>
<p>Ideas?</p>

2314 | 1 | null | 2010-08-15T13:01:53.903 | 5 | 6058 | <h2>Background</h2>
<p>I'm running Ubuntu as a guest OS in a VM. Originally the VM was created with Ubuntu 9.10 64-bit and with vmware-tools installed, when I resized or maximized the VMware Player, the guest OS was correctly and automatically resized. Once I upgraded to Ubuntu 10.04 (not reinstalled), automatic resizing no longer works. However, the mouse and network drivers do continue to operate properly.</p>
<p>When installing vmware-tools in 10.04, I notice a lot of LSB warnings for upstart jobs that were not thrown when installing it in 9.10. </p>
<h2>Environment</h2>
<ul>
<li>Distro: Ubuntu 10.04 64-bit</li>
<li>Kernel: Linux nitrogen 2.6.32-24-generic #39-Ubuntu SMP Wed Jul 28 05:14:15 UTC 2010 x86_64 GNU/Linux</li>
<li>VMware Player: 3.0.1 build-227600</li>
<li>Host OS: Windows 7 Home 64-bit</li>
</ul>
<h2>What I've already tried:</h2>
<ul>
<li>Reinstalling vmware-tools</li>
<li>Updating to the latest <em>patch</em> level of VMware player 3.0.1</li>
<li>Updating all installed Ubuntu packages, including kernel (and then re-install vmware-tools)</li>
<li>Manually creating entries in xorg.conf for the host's fullscreen resolution</li>
</ul>
<h2>Problem</h2>
<p>When I resize or maximize the VMware Player window, the guest OS size stays fixed.</p>
<h2>Question</h2>
<p><strong>How do you configure vmware-tools for VMware Player 3.0.1 in Ubuntu 10.04 64-bit to enable automatic guest resizing?</strong></p>
<h2>Update</h2>
<p>I don't know exactly WHY this fixed my issue, but on Aug 28th, 2010 a set of package updates came out that (see below), after installation, magically resolved this issue. I'm Guessing it has something to do with the xorg packages.</p>

<p>Since I've got a slow, laptop harddrive, <code>ureadahead</code> itself takes ~50s of the boot time. Then, the rest of the visible boot sequence takes another 100s to complete, using a lot of CPU, but not maxing it out and lots of IO (again, 100% almost all the time).</p>
<p>This seems just strange to me. Is my <code>ureadahead</code> misconfigured? Why does it block tasks like bringing up the network which seems to be taking lots of cpu? Should it take ~50% of the bootchart time in general?</p>
<p>Edit: here is the example bootchart: <a href="http://img191.imageshack.us/img191/1049/localhostkarmic20100815.png">http://img191.imageshack.us/img191/1049/localhostkarmic20100815.png</a> (or this if the direct one didn't work: <a href="http://yfrog.com/f/5blocalhostkarmic20100815p/">http://yfrog.com/f/5blocalhostkarmic20100815p/</a> )</p>

The reason to do this is that the primary reason for disc slowness is seek times - even slow hard drives should be able to push out >50 MB/sec reads, but if you need to seek around - at tens of <i>milliseconds</i> per seek - that decreases dramatically. By running ahead of time, ureadahead should be able to minimise the seeks and hence minimise the time needed to read all the data your boot will need.</p>\n\n<p>So, the <i>ideal</i> bootchart looks like ureadahead at 100% I/O utilisation, followed by everything else starting up and using no (disc) I/O. This boot isn't practically achievable, not least because many of the services we're starting up write to the disc, but that's the idea.</p>\n\n<p>Looking at your bootchart it seems that ureadahead is having a hard time actually pulling data off your disc - there's lots of time where it's at a very low throughput. Even so, it looks like it's doing some of its job - after ureadahead starts your boot is mostly CPU bound, rather than I/O bound, and it looks like the large patches of I/O-bound boot are associated with <code>preload</code> firing up. </p>\n\n<p>You might want to try removing <code>preload</code>, or to reprofile your boot¹, or it might be that some of your files are very fragmented, or it might be a bug in ureadahead.</p>\n\n<p>1: Removing the <code>pack</code> files from /var/lib/ureadahead will cause ureadahead to reprofile on your next boot.</p>\n",

Dependency issues are easily resolved by creating dummy packages and installing the correct packages yourself. Further, a great deal of the packages are Debian packages recompiled unmodified on Ubuntu -- all packages with version numbers that don't end in <code>-0ubuntu1</code> or more generally <code>-XubuntuY</code>. IIRC, greater than 75% of packages in Ubuntu are unmodified. Clearly dependencies aren't such a huge issue.</p>\n\n<p><em>Binary compatibility</em> is something you should be more afraid of. Ubuntu is <a href=\"https://wiki.ubuntu.com/MarkShuttleworth#What%20about%20binary%20compatibility%20between%20distributions?\" rel=\"nofollow\">not always binary compatible</a> with Debian. It maybe at times, it may not at other times. Packages on Launchpad PPAs are complied in a clean root <em>Ubuntu</em> environment not <em>Debian</em>. Should it be that at the given time the two are not binary compatible, the package will break on your computer.</p>\n\n<p>So, here's the best way to do this (although not the quickest). Install <code>pbuilder</code>. Add the PPA's source repository to your software sources. Download the source package using <code>apt-get source foobar</code> and then run <code>sudo pbuilder build foobar-1.2.3-0ubuntu4ppa5.dsc</code>. (Please save yourself some time and use tab auto-completion, don't try to remember which version was downloaded). This will build the package from source and give you a binary compatible (since you compiled it on your own machine) <code>.deb</code> that you can install available in <code>/var/cache/pbuilder/result/</code>.</p>\n",

2344 | 1 | null | 2010-08-15T23:44:10.620 | 2 | 3530 | <p>The audio configuration must have changed from 9.10 to 10.04, because audio no longer seems to work with DOOM 3. This was the suggested way to run DOOM 3 before, and it worked fine:</p>
<pre><code>doom3 +set s_alsa_pcm plughw:0
</code></pre>
<p>However, DOOM 3 is completely silent after I upgraded to Ubuntu 10.04. Has anyone gotten the audio for DOOM 3 to work in Lucid Lynx?</p>
<p>Edit: Here's some potentially useful console output:</p>
<pre><code>------------------------------------
dlopen(libasound.so.2)
asoundlib version: 1.0.22
Alsa is available
------ Alsa Sound Initialization -----
snd_pcm_open SND_PCM_STREAM_PLAYBACK 'plughw:0' failed: Device or resource busy
dlclose
WARNING: sound subsystem disabled
</code></pre>
<p>Edit2: Well, it seems that DOOM 3 is unable to share, like other applications, so closing
Rhythmbox and Chrome and anything else that shows up in Sound Preferences under the
Applications tab worked. I would like to get it to play nice like everything else, but
that may be too much to ask. If someone can come up with a solution that causes DOOM 3 to
coexists peacefully with other applications would constitute an accepted answer. It sucks
to have to close everything else first.</p>

<p>Please don't suggest alternatives unless you can show they are faster than kqemu at disk I/O and networking on a VT-free machine.

2352 | 1 | 2359 | 2010-08-16T02:51:00.277 | 9 | 4365 | <p>I was wondering if anyone has a workaround for VNC remote not working with Ubuntu running compiz. From what I can tell it works if I disable compiz effects, but who's not a fan of eye candy? Anyway, it's not a huge deal if there's no work around anyone knows because I've been using nx server instead to remote connect to my desktop. I was just wondering if there's a way to get VNC working because I have an app on my ipod touch that can VNC, but there's no NX client for the itouch.</p>

Xen, OpenVZ, KVM, Vservers, EC2 and Solaris Zones, although this is just a sample list and the question is not exclusive to these.</p>
<p>From the community's experience, what virtualization solution should I use on Ubuntu to learn with?
Factors are ease of setup, ease of use. Stability is also important. Secondary are memory usage and performance issues. </p>
<p>What do I want to virtualize? Well, pretty much anything the chosen software will allow, under the banner of experimentation.</p>

In every line you can define one command to run and its schedule, and the format is quite simple when you get the hang of it. The structure is:</p>\n\n<pre><code>minute hour day-of-month month day-of-week command\n</code></pre>\n\n<p>For all the numbers you can use lists, e.g. <code>5,34,55</code> in the minutes field will mean run at 5 past, 34 past, and 55 past whatever hour is defined.</p>\n\n<p>You can also use intervals. They are defined like this: <code>*/20</code>. This example means every 20th, so in the minutes column it is equivalent to <code>0,20,40</code>.</p>\n\n<p>So to run a command every Monday at 5:30 in the afternoon:</p>\n\n<pre><code>30 17 * * 1 /path/to/command\n</code></pre>\n\n<p>or every 15 minutes</p>\n\n<pre><code>*/15 * * * * /path/to/command\n</code></pre>\n\n<p>Note that the day-of-week goes from 0-6 where 0 is Sunday.</p>\n\n<p>You can read more <a href=\"https://help.ubuntu.com/community/CronHowto\" rel=\"noreferrer\">here</a>.</p>\n",

<p>The notebook has 6Gb RAM, 4 Cpu's (Core i3 330M) @ 2,13GHz, and an ATI Radeon HD 5650 (with ati closed drivers).. its a new notebook.
The Desktop has 2 Cpu, 4Gb ram and an Intel graphic card.. its 5 years old.</p>
<p>I dont know why, but when i show/hide tilda (i use it in fullscreen mode with opacity), in the desktop show up instantly, instead in the notebook take 2~3 seconds.</p>
<p>Why the notebook is slower, even if it is more powerfull?</p>
<p>Can be a matter of drivers/graphic card type, or there is some configuration i can check?</p>
<p>On both I did install tilda from ubuntu software sources.</p>
<p><strong>EDIT:</strong>
I just noticed that it happens when i try to maximize every window (a terminal, google chrome, gedit, etc..), if i press F11 to maximize it: in the notebook it takes few seconds, in the desktop is instantly.</p>
<p>Could it be a compiz setting?</p>

<p>So my <kbd>Fn</kbd> + <kbd>Up</kbd>/<kbd>Down</kbd>/<kbd>Left</kbd>/<kbd>Right</kbd> keys are mapped to brightness/volume. I would much rather them be mounted to <kbd>Page Up</kbd>/<kbd>Page Down</kbd> and <kbd>Home</kbd>/<kbd>End</kbd>. And map the other 4 keys to these 2. The page <kbd>Page Up</kbd>/<kbd>Page Down</kbd> has <kbd>Fn</kbd> + them for <kbd>Home</kbd>/<kbd>End</kbd>. Its a shitty keyboard layout but I want to make it work.</p>
<p>Anyone knows how to figure out what the keycodes are and how to remap them?</p>
<p>Version: 10.04 x32</p>
<p>So here are some experiments:</p>
<p>Using xmodmap -pke I discovered that keycodes 122 = vol down, 123 = vol up. And I got all the info for Home/End/Page Up (next), Page Down (prior).</p>
<p>Now when using the vol up keys, there are no events being fired that <code>xev</code> can detect.</p>
<p>I can remap the volume keys to <code>XF86AudioLowerVolume</code> or <code>XF86AudioRaiseVolume</code>, but once I map those two to Home/End (respectively) they don't do anything. <code>xev</code> still does not pick up these events after a remap.</p>

2411 | 1 | 2537 | 2010-08-16T19:22:44.867 | 301 | 236305 | <p>I think I'm being the victim of a bug here. Sometimes while I'm working (I still don't know why), my network traffic goes up to 200 KB/s and stays that way, even tough I'm not doing anything internet-related. </p>
<p>This sometimes happens to me with the CPU usage. When it does, I just run a <code>top</code> command to find out which process is responsible and then <code>kill</code> it. Problem is: I have no way of knowing which process is responsible for my high network usage. Both the resource monitor and the <code>top</code> command only tell me my total network usage, neither of them tells me process specific network info.</p>
<p>I've found questions here about monitoring total bandwidth usage, but, as I mentioned, that's not what I need. Is there another command I can use to find out which process is getting out of hand?</p>
<p>The command <code>iftop</code> gives results that disagree entirely with the information reported by System Monitor. While the latter claims there's high network traffic, the former claims there's barely 1 KB/s.</p>
<p>I've already tried killing all the obvious ones (Firefox, update-manager, Pidgin, etc) with no luck. So far, restarting the machine is the only way I found of getting rid of the issue.</p>
