Problem with intel gma 950

Hi!
I've installed archlinux today, for the first time. I've a problem with X.
I've succesfully installed the intel driver, and it works.
If I run "startx" from root, xterm starts and the output of glxgears is ok.
But if I run glxgears when I'm in gnome, seems that the output of glxgears is very ugly.
I can't understand..

Here is my xorg.conf:

Section "ServerLayout"
    Identifier     "X.org Configured"
    Screen      0  "Screen0" 0 0
    InputDevice    "Mouse0" "CorePointer"
    InputDevice    "Keyboard0" "CoreKeyboard"
EndSection

Section "Files"

    FontPath     "/usr/share/fonts/75dpi:unscaled"
    FontPath     "/usr/share/fonts/TTF"
    FontPath     "/usr/share/fonts/Type1"
EndSection

Re: Problem with intel gma 950

If you have Compiz enabled, disable it. It plays hell with 3D stuff.

Also, why is compositing enabled in xorg.conf?

Re: Problem with intel gma 950

There is a problem of permissions..
In gnome or xterm, if I run "glxgears" from root, I've the right ouput, if I run it from my user, the output is "ugly":

[root@myhost sergej]# glxgears 
3119 frames in 5.0 seconds = 623.648 FPS
2975 frames in 5.0 seconds = 594.800 FPS
3288 frames in 5.0 seconds = 657.560 FPS
3258 frames in 5.0 seconds = 651.447 FPS
^C
[root@myhost sergej]# exit
exit
[sergej@myhost ~]$ glxgears 
538 frames in 5.0 seconds = 107.433 FPS
543 frames in 5.0 seconds = 108.598 FPS
554 frames in 5.0 seconds = 110.619 FPS
^C
[sergej@myhost ~]$

Have I to add some group to my user?
