You might be able to get it working by modifying you XFree86-4.config file
(/etc/X11/ directory). I don't recall all the specific modules that need to
be loaded for hardware accel to work - you can find the info at the DRI-CVS
site, which also ties into your next option if simply adding entries to the
config file fails to work. The website:
http://www.xfree86.org/4.0.2/DRIcomp.html has instructions on not only
downloading, building, and installing dri-cvs code, it also has information
as to what is needed in your XFree config file mentioned above. The docs
generally refer to XFree86.config which is NOT the correct file on Mandrake,
it is XFree86-4.config.
Also make sure the correct kernel module is loading for your video
card...mine is radeon.o, and it must be loaded for the XFree hardware opengl
accel to work.
You can add the entries listed in this documentation to your XFree config
file, restart and then run "gears" from an xterm/konsole and see if hardware
accel is working.
I have an ATI Radeon. With software rendering, I get about 120 FPS in the
default gears window size. With hardware accel, I get more than 1000 FPS
(really). So, there is obviously a difference. The framerate will display
on your konsole/xterm every 5 seconds, if you are wondering, so you run it
for a while and get an idea of your average framerate. Don't do anything
else while it is running.
Anyway, if adding glx, etc, modules to your config file and restarting
doesn't do it, then I suggest following the instructions for downloading and
building the dri-cvs code. I have VERY rarely had any problem building it
and getting it working. It just does and the proceedure is really not
difficult. I build a new DRI-CVS download every few days at the moment as I
try to work through some game opengl issues (apparently, XFree86-4.0.3 has
some problems that weren't there in 4.0.2 or 4.0.1 in this regard). The
dri-cvs code is periodically incorporated into the XFree86 tree and that is
what gets installed by default. By directly using the dri-cvs, you will be
replacing certain parts of the default XFree86 with the latest code, which
often works better. It has for me. Back in March, I was getting 860 FPS in
gears, and now, as I said, I get over 1000 FPS.
