opengl problem on xorg 6.7 with ati radeon 8500
 

Everytime when I start an opengl app it's working wery slow. When I start for example tuxracer, it is working extremely slow. When i start tuxracer from console,a message message appears on the console:

You need to install the ATI drivers from the ATI site.

After you do this, it should speed things up. I had the same problem untill i installed my ATI drivers.

What are you getting in with glxgears and fgl_glxgears?

well, i installed it (than was REALLY difficult!) and i run fglrxconfig and everything seemed to look fine, but then when i restarted X, it didn't work
the error message comes here:
getconfig.pl: version 1.0
getconfig.pl: Xorg Version : 6.7.0.0.

Whats the matter?



And now the graphics is working even worse than before!

try running xorgcfg or xorgconfig (i believe that's the config commands) See if you can set it up that way.

Or wait till someone with more experience can help here. Consider this a Bump on your topic as well as some help. :)
