Distorted screen with direct rendering

Well, when I try to start a game (tuxracer ;)) the screen is all messed up :(
Well, direct rendering is ok.... so does anybody now what the problem is??

Later i'll give XF86Config and that kind of stuff ;)

It would be better to give your XF86Config now. What is your video card, and what drivers are you using?

Yeah, yesterday it was late, and now i got all information ;):)

XF86Config-4:

The XF86Config is in the post below!

I just made it, but it works ;)

Some things about my computer:
AMD 1800+
Using unstable Debian
Ati 9000 Pro (128MB)
fglrx as video driver
19" inch monitor (could the HorizSync VertRefresh setting distort?? don't know the exact values :()

Well, that was all about it..... Let me know if you know the solution ;):)

oh, that XF86Config is wrong (dri isn't working with it (agp init failed)
this is the one dri is working with:

Well, I just found out something strange.... I wanted to make a screenshot of the game (with the distorted screen) when he took it.... TuxRacer returned to windowed mode and in windowed mode the picture is fine, no rendering problems.... but how comes that the screen in fullscreen is distroted? Some kind of switch in XF86Config?? I don't get it....

I think that's a known problem with the ATi drivers, check the manual for them on the website. You could try uncommenting this line in your XF config:
# BusID "PCI:1:0:0" # vendor=1002, device=496e
By the way, next time you get a new video card, try nVidia, their support is much better.

thanks, i'll try...
and yeah nvidia is definitely the next card to be found in my pc ;):)

more suggestions?
