So, I installed the driver from ati for my computer.
The original driver worked ok for my laptop, but couldnt run the extern 27" that I have.
The install went fine. I followed the ATI instruction, but…
There is a lag in the refresh rate or something. When I move a window it gets blurry and hangs up. Also when I use the roller ball on the mouse the open windows just rolls by in a blur.
I had the same problem on fedora 9, but it seemed to go awoy after I restarted the computer a few times. That isnt the case on openSuse
ATI 2400HD
openSuse 11
KDE 3
any ideas?
