User groups and intel gma3150 hardware acceleration
I have crunchbang statler xfce installed on my netbook.
And everything used to work (with some work arounds for somethings) till i updated the system last week, and now i dont have hardware acceleration.
When i run glxinfo as user i get the error segmentation fault, but as root everything seems to be okey.
/var/log/xorg.0.log shows that the intel driver is loaded normaly. So this looks to me that i might not be in the right group. But grep video /etc/group gives as output: video:x:44:mardo
I even tried chancing the the DRI group to mardo in the xorg.conf without sucses
Code:
Section "DRI"
Group "mardo"
Mode 0666
EndSection
Code:
mardo@crunchbang-netbook:~$ ls -l /dev/dri/card0
crw-rw-rw-+ 1 root mardo 226, 0 Mar 19 11:33 /dev/dri/card0
I have no idea what is going wrong here...

Run 'LIBGL_DEBUG=verbose glxinfo' and see if you get any more debug information.

That gives basically the same output as glxinfo

Hmmm... Try running 'ldd /usr/bin/glxinfo' as both root and user and see if it's linking to all the same libraries.

Thanks i had not thought of that yet. But i have already found the solution!
I tried making a new account, in this test account i had hardware acceleration.
So i started thinking what config files do i have in my account that influence opengl, driconf... So i removed driconf (purge) and after a reboot everything works again
Have no idea how and why driconf changes the permission to glx...
