How to play openGL based games with full 3D acceleration on XGL/compiz

[Kratos]

Hi all! I'd just like to confirm that this script does work on KDE with an nVidia 6200 AGP. Thanks for the script!

this doesnt work for me at all. Im running xgl as a gnome session.

when i try use `nonXgl ppracer` it returns:
andrew@francis:~$ nonXgl ppracer
xhost: unable to open display ":93"

and when i type `ps uax | grep Xorg | grep Xgl' it returns nothing:
andrew@francis:~$ ps uax | grep Xorg | grep Xgl
andrew@francis:~$

any suggestions?

Hi,

did anyone try to follow the instructions with the 8.27.10 ATI-drivers installed?

My display is appearently not 93 but when I do the

sudo gedit /usr/bin/nonXgl

like you said it comes back with nothing.

well, performance is HORRIBLE even with high end graphic cards, but I guess it's a start

[snop3]

this is functional for ati cards on dapper and i have 8.25.18 ati drivers
i have this script in /ust/local/bin/nonXgl

#!/bin/sh
DISPLAY=":0"
if [ -z "$1" ]; then
        echo "Usage: nonXgl <command>"
        exit 1
fi

LD_PRELOAD=/usr/lib/libGL.so.1.2 $@

i mean this is functional with other ati drivers
that is all what do you need for run opengl applications in Xgl with opengl acceleration

I have an ATI radeon x800 xl agp card and Kubuntu dapper
It works perfectly, but i change

LD_PRELOAD=/usr/lib/libGL.so.1.2 $@

with

LD_PRELOAD=/usr/lib/libGL.so $@

cause libGL.so.1.2 don't exist in my /usr/lib folder

i try also libGL.so.1


generaly this method works but it reduce more the performace of game than without Xgl, loading and after when u play the perfomace are not acceptable in my computer (2gb ram, athlon xp 2600, 120gb hd).

if you are having trouble running a command such as (with spaces and/or quotes):

nonXgl wine "C:\Program Files\Steam\steam.exe"

modify your /usr/bin/nonXgl exec line to this:

exec "$@"
