[gentoo-user] direct rendering only works with root???

[Mauro Arnoldi]

I installed ati-drivers and "partially" works correctly:

As user nothing works:
-------
mauro@aghartilap ~ $ fglrxinfo && glxinfo | grep rendering
libGL error: failed to open DRM: Operation not permitted
libGL error: reverting to (slow) indirect rendering
display: :0.0  screen: 0
OpenGL vendor string: Mesa project: www.mesa3d.org
OpenGL renderer string: Mesa GLX Indirect
OpenGL version string: 1.2 (1.5 Mesa 6.4.2)

libGL error: failed to open DRM: Operation not permitted
libGL error: reverting to (slow) indirect rendering
direct rendering: No
-------

with root:
-------
mauro@aghartilap ~ $ su -
Password:
aghartilap ~ # fglrxinfo && glxinfo | grep rendering
display: :0.0  screen: 0
OpenGL vendor string: ATI Technologies Inc.
OpenGL renderer string: MOBILITY RADEON X300 Generic
OpenGL version string: 2.0.5879 (8.26.18)

direct rendering: Yes
-------

So now I'm using KDE without the hardware acceleration... Can someone help me 
fix it?

Thanks

Mauro

Check your xorg.conf for the following:

Section "DRI"
    Mode 0666
EndSection

Or for a bit better security:

Section "DRI"
    Group "graphics"
    Mode 0660
EndSection

And then make sure your user is a member of the graphics group.

I think it's common practice to use the existing 'video' group for this. As 
opposed to making a whole new graphics group.

No objection to using an existing group.  But in fact, I have both
video and graphics groups, and I didn't create either one of them
myself.

I have a very similar (with an intel i955 card and gnome)...

but this line is already in my xorg.conf. 

Furthermore, it only happens in my first session. If I logout and login
again (trough gdm), direct rendering works for the normal user !

Has someone any idea to explain this ?

Is your udev putting the permissions correctly? This was one of the
issues previously.

 $grep dri /etc/udev/rules.d/50-udev.rules 
# dri devices
KERNEL=="card*",        NAME="dri/card%n", GROUP="video"

I've just checked, and I'm not in the video group ! I guess that's the
problem, but then, why does it work after logout and login ?

I have exactly the same line in 50-udev.rules, but I didn't understand
wether it meeans that I have this problem or that it has been solved ?
