ATI Open driver has acceleration only on root

I really don't know what to do.

glxgears
gets ~80FPS

, but

sudo glxgears
1700 FPS.

Other programs other need root to have an acceleration. What is going on, how to fix it?
I have a Radeon 9550, R300. These results (last two) could visualize my problem:

glxinfo | grep direct
direct rendering: Yes

dmesg | grep agp
