Scrolling/dragging window lag with latest drivers

[bp787]

I'm having some problems with the last few ATI updates I installed. I'm having a problem (that I've seen on some older systems before...and fixed), where scrolling in webpages is horribly slow especially if flash is in use, and with dragging windows around. There's no "Smooth" dragging.

also, I now get a "Bus error" when running amdcccle...

I'm using Fedora 11 x86_64. I have Compiz installed, but it's disabled. I first used the latest xorg updates from fedora. No luck. Next, I installed the ati drivers from ati. No luck (actually caused me problems with my DVI based KVM switch.

kernel info: Linux foo 2.6.30.10-105.2.23.fc11.x86_64 #1 SMP Thu Feb 11 07:06:34 UTC 2010 x86_64 x86_64 x86_64 GNU/Linux


here are the installed xorg drivers:

xorg-x11-drv-ati-6.12.2-14.fc11.x86_64
xorg-x11-drv-catalyst-libs-10.1-1.fc11.x86_64
xorg-x11-drivers-7.3-11.fc11.x86_64
xorg-x11-drv-catalyst-10.1-1.fc11.x86_64

Here is the xorg.conf file that's in use:

I can provide the xorg log if desired as well.

Thanks for any help you can provide in advance!

Firstly try to generate a fres xorg.conf with "aticonfig --initial".
If that makes no difference you can try downloading https://a248.e.akamai.net/f/674/9206...x86.x86_64.run

run the installer as root (sudo sh ati-driver-installer-10-3-x86.x86_64.run) . When its done you can again generate a
fresh xorg.conf with "aticonfig --initial".
