Ubuntu 9.10 & Urban Terror

Sunday, November 22, 2009 | Written by PreviousN

Readers at the Ubuntu Forums are reporting that the upgrade to Ubuntu 9.10 is causing strange behavior with mouse movement in Urban Terror and other 3D games. Worse is that some are reporting random crashes and runaway processes that can only be stopped with the kill command. It seems that a fix has been found for the random crashes, as it is caused by the lack of a needed pulseaudio library. There has yet to be a fix found for the strange mouse behavior, and it does not affect all users.

The Fix

Fix the random crashes by running this command in a terminal: “sudo apt-get install libsdl1.2debian-pulseaudio”. This will also fix similar problems with other SDL games. Here is a link to the Urban Terror Forums fix.

Help Us Out

If any reader out there knows how to fix the mouse issue, please submit the fix in the comments or on the Urban Terror Forum’s thread about the issue. Until a fix is found readers may want to wait to upgrade their Ubuntu install.

    First remove pulse audio from system, that shit doesnt work well with urban terror and mumble.after that install alsa sdl.

    Mouse, try put thes lines in xorg.conf:
    in section module:

    Section “Module”
    Load “extmod”
    SubSection “extmod”
    Option “omit xfree86-dga”
    EndSubSection
    EndSection

    The best solution is to make own xorg.conf and turn off auto detection of HAL in xorg.conf using the command below and assign mouse and keyboard drivers to “mouse” and “kbd” available in the repository and assigning them statically in config.

    Section “ServerFlags”
    Option “DontZap” “false”
    EndSection

    mouse and keyboard example:

    Section “InputDevice”
    Identifier “Mouse0″
    Driver “mouse”
    Option “Device” “/dev/input/mice”
    Option “Protocol” “ExplorerPS/2″
    Option “ZAxisMapping” “4 5″
    Option “Emulate3Buttons” “false”
    Option “Resolution” “450″
    Option “SampleRate” “500″
    EndSection

    Section “InputDevice”
    Identifier “Keyboard0″
    Driver “kbd”
    Option “XkbModel” “pc105″
    Option “XkbRules” “xorg”
    Option “XkbLayout” “pl”
    Option “XkbOptions” “terminate:ctrl_alt_bksp”
    EndSection

    Ubuntu and especially Gnome has always been slow with urban terror. I strongly suggest for all Ubuntu users to install lxde or fluxbox for urban terror. Gnome is slow and it lags urt.

    Now. When using the proper window manager, linux is so much faster than windows and has better frame consistency. Just don’t use gnome for gaming.

      Hi ]3east,

      Fluxbox is a little too minimal for my tastes. I haven’t heard much about lxde. I have tried xfce, and I think its pretty good, but it really didn’t boost my performance when running urban terror compared to gnome. The issues above sound like they are caused by the sound system rather than the window manager. I don’t exactly love pulseaudio (I’ve experienced dropped sound etc. in UrT), but I use skype and audacity a lot and have zero problems with it. I also have mumble working via pulseaudio. I didn’t have much trouble with alsa either. I just don’t want to be someone clinging to the old while the rest of the linux community moves on.

      What are your thoughts on kde (either 3.x or 4.x) and urban terror? Any performance improvements? I’m running a pretty much vanilla install of ubuntu on most of my computers and am thinking about switching to a different distro (linux mint is the top choice). I use kdenlive for video editing and it’s buggy using gnome. So I’m mostly thinking about switching to a kde based distro.

        I was not talking about the bug with the processes. That’s pulse audio. I am talking about the choppiness in FPS and graphical performance.

        KDE does work better than GNOME for gaming. BUT if you want maximum performance use lxde of fluxbox. Even though both of those are small, you can swap between Gnome/KDE and a minimalist desktop. LXDE and Fluxbox take up very little space and you can log into them from your Gnome login menu. Click “Sessions” then “[other windowmanager of your choicer]”

        Also, I would stick with ubuntu. Because there is much more support and repositories that most other distros do not have. If ubuntu is not fast enough for you, I would suggest removing applications and programs that you do not need.

        If you do know what you are doing with linux, then by all means go ahead and try a new distro. For the most speed, I would suggest installing and configuring slackware, I have a IRL friend who uses it and it’s wicked fast, even on old machines. BUT you really do have to know what you are doing before you install slackware.

          I used to use slackware, and I had it running for about a year. It’s fast and stable. But any updates are a pain. Slackware has their own packaging system, but it’s not nearly as advanced as .deb/apt. Last time I used it the system didn’t have dependency resolution.
          So in terms of effective resource utilization: Fluxbox > LXDE > XFCE > KDE 3 > Gnome > KDE 4? BTW: Linux mint is based on ubuntu, so most of the support on the forums still applies, kinda like debian vs. ubuntu.

          Anyways, the main point of this current response is about the mouse problem. I did some research and it looks like the bug is in Xorg. This is bad news even though there’s a fix committed upstream (according to https://bugs.freedesktop.org/show_bug.cgi?id=24737). This is bad news because usually xorg updates aren’t propagated until the next point release unless it’s a major bug. And this bug isn’t classified as “major” (It’s listed as “low priority” on launchpad). Good news is that it only affects some mice.

            Yeah I figured it had something to do with the graphical setup of xorg, drivers, etc. Though I have found that not using Gnome has solved my problem however it may be different for others.

      Keyhole:

      Most Hollywood studios use linux for renderfarms, etc. Some of the actual editing is even done on linux. It’s far from lacking in the audio/visual department. The main hiccups are in usability for the average end-user, IMO.

      Overall, there are some REALLY good alternatives to audio visual programs out there. Getting them to run without bugs or hiccups can sometimes be a challenge.

      Musix
      The name should be self explanatory. The distro is based on Debian / KNOPPIX. It’s a live disto with an HD installer. Native language is Spanish I think, but it’s easy to switch to w/e language you want, pre-installation.

      http://www.musix.org.ar/en/

      I’d say krwisty has the best solution for the mouse, don’t think the keyboard is necessary though, since that’s not apparently the problem. I don’t know, I don’ t use Ubuntu, too “mainstream” for me. I prefer the distro that gets me paid, BackTrack

    I give a little solution for linux users who can not hear normal hitsound in game.
    Original hitsound: http://dl.dropbox.com/u/1199535/hit.wav
    Long time i heard instead of that some kracking ugly sound.
    And this really disrupted me.
    Finally i find easy solution: copy zpak000_assets.pk3 in your /home/username/.q3a/q3ut4/ folder.

    That’s why you shouldn’t play FPS with Linux. Because Linux sucks.

      Thanks for the tip. I recently upgraded to ubuntu 9.10 (I bit the bullet, so to speak), and had one of those “it’s a feature, not a bug” experiences.

      Apparently, Ubuntu 9.10 recognizes when it is on a laptop and makes adjustments to the touchpad settings and the like. Under the system –> preferences –> mouse, there is a checkbox that makes the mouse movement pause when a keystroke is pressed. It comes checked by default (wtf?!).

      So, before I found that out, I would move in a choppy way (VERY frustrating).

      I tried installing debian a few weeks ago, but since I don’t have a cd drive it was a pita. For some reason any usb installer I tried didn’t work. At all. I spent >5 hours on it and really didn’t want to mess with it anymore. Well, everything is good now.
