Red Hat Bugzilla – Bug 25491
r128.o module does not produce 3d acceleration
Last modified: 2007-04-18 12:31:02 EDT
From Bugzilla Helper:
User-Agent: Mozilla/4.76 [en] (X11; U; Linux 2.4.0-0.99.11 i686)
The r128.o module will load and claim that it is in use (via lsmod) but
OpenGL programs do not take advantage of it.
Steps to Reproduce:
Actual Results: It made the computer crawl
Expected Results: It should have been fast
Video Card is ATI Rage Fury 128
It's up to the X server to do/use the actual acceleration. Reassigning.
A couple of things to look at:
* Ensure that the glx and dri modules are being loaded from the module section
* Check the permissions on /dev/dri/card0 to make sure that you have read and
write access to the device
* Run glxinfo to see if it shows that direct rendering is enabled
We (Red Hat) should really try to fix this before the next release.
The /etc/X11/XF86Config-4 file was missing a line.
Mode 0666 <-- This
Only root had 3D acceleration and regular users did not. I think it would be
nice if all users had permission to DRI by default.
That in the past has been bad (all users could lock the machine).
Currently to do this you must
a) log in as root
b) log in via xdm/kdm/etc.
