• Turn off "Desktop Effects" in "System Settings" / "Desktop". Otherwise you may get display errors, or really low fps. Benchmark results on my system (with a Geforce 7600GT and the newest nvidia driver from the Ubuntu repositories):
  

  With desktop effects enabled: result 1910 frames 93.1390000 seconds 20.5069842 fps, one-second fps min/avg/max: 10 22 42 (90 seconds)
  Without desktop effects: result 1910 frames 49.5830000 seconds 38.5212674 fps, one-second fps min/avg/max: 19 43 74 (90 seconds)

• Install the nvidia driver, or whatever your graphics card needs. It is NOT preinstalled! Run the program "jockey" (Kubuntu: "jockey-kde") to do that. You should find it in the start menu when you look for "Hardware" (just type it while the menu is open).
• Run "nexuiz-linux-sdl.sh", not "nexuiz-linux-glx.sh", or you won't get sound. If you do want to run the glx version, prepend "pasuspender" and a space to the command line. Bug in the alsa pulseaudio module is known, but we have a workaround for it in DarkPlaces svn.
• If you, like me, get really bad bugs like delayed input events (e.g. in the menu, I move the mouse right, stop, then down, then it first goes a bit right, also, clicks are delayed), add lines like these to /etc/X11/xorg.conf:
  

  Code: Select all

  Section "ServerFlags"
        Option "AutoAddDevices" "False"
EndSection

Section "InputDevice"
        Identifier "mouse"
        Driver     "mouse"
        Option     "CorePointer" "True"

        Option     "Emulate3Buttons" "False"
EndSection

Section "InputDevice"
        Identifier "kbd"
        Driver     "keyboard"
        Option     "CoreKeyboard" "True"

        Option     "XkbRules" "xorg"
        Option     "XkbModel" "pc105"
        Option     "XkbLayout" "de"
        Option     "XkbVariant" "nodeadkeys"
EndSection

  
  
  Bug reported on https://bugs.launchpad.net/ubuntu/+sour ... bug/295912, a workaround is manually turning off mouse acceleration using xset, and then using vid_dgamouse 0 for GLX, or setting the env variable for SDL DGA support to 0 for SDL. In DarkPlaces svn, turning off the mouse accel with xset is not needed if you use GLX.

A related note to those using Xorg 1.5.2 or newer, some distributions (ubuntu 8.10 included) don't disable 3 button emulation - its supposed to be disabled automatically if X detects a middle button press, but for some reason thats not working. This causes a latency for ALL button presses since the server waits a while in order to detect right+left press as a virtual 3rd.

Here's how to disable 3 button emulation alltogether, its no longer done in the xorg.conf file but has moved to HAL:

Add the following inside the <device> section in /usr/share/hal/fdi/policy/10osvendor/10-x11-input.fdi:

Code: Select all


   <match key="info.capabilities" contains="input.mouse">
      <merge key="input.x11_driver" type="string">mouse</merge>
      <match key="/org/freedesktop/Hal/devices/computer:system.kernel.name"
             string="Linux">
        <merge key="input.x11_driver" type="string">evdev</merge>
      </match>

      <!-- this here is what actually disables the 3 button emulation - the rest above is just the default stuff found in this file -->
      <merge key="input.x11_options.emulate3buttons" type="string">False</merge>
    </match>


It will get picked up once the system-wide HAL instance is restarted, easiest is to reboot.

Yes, HAL will need to work a little bit to get into my favorite list of things on this planet, but its not mission impossible

You can remove xkblayout de. Not all are germans.

Ooh, and that hal config file. How do they think users could possibly configure it?

[divVerent]

There are more Germans here than English speaking one. That xorg.conf section was just an example after all.

And by going this xorg.conf way, the HAL config file is not needed. As it seems evdev is severely flawed, HAL's handling must be turned off for a good experience.

There is a handy program called compiz-switch in the repositories for doing this. It toggles effects with just 1 click.

Just wanted to add this comment abount the 9800 series Geforce cards. If you have an Nividia Geforce 9800 installed in your machine then DO NOT use the Ubuntu supplied driver. Instead download the driver off of Nvidia's website and install it the hard way (going into root and all that good sh!t). The Ubuntu supplied driver DOES NOT WORK. Here's a tutorial I used on my 64 bit 8.04 machine:

For newest nvidia drivers for ubuntu use this repository. Just add the deb and deb-src to your /etc/apt/sources.list

Seems like people have a problem with sticky/freezing keys/mouse button in xorg/ubuntu.

Video.

Steps to reproduce in ubuntu Jaunty:
1. Start Nexuiz 2.5.1.
2. Play Single player - Level 1.

If you have problem with this as well, please reproduce the bug and open a terminal and do this:
lspci -vvnn > lspci.log
cat /var/log/Xorg.0.log > Xorg.0.log
cat /var/log/Xorg.0.log.old > Xorg.0.log.old

Report to launchpad by attaching those three .log files here.
