Flickering video on Asus motherboard with ATI video

[Dotan Cohen]

I have Kubuntu 8.10 installed on a machine with an ASUS motherboard,
onboard ATI graphics:
http://www.asus.com/products.aspx?l1=3&l2=149&l3=639&l4=0&model=2064&modelmenu=1

The system graphics seem very sluggish (switching photos in digikam is
slow) and video flickers. Running "aticonfig --initial" helped
somewhat, but not completely. I am using the proprietary fglrx driver.
Opening the Proprietary Drivers windows informs me that the machine is
using "a different version" of the driver, for what that's worth.
Looking in Adept, I have the only version available, installed.

What can I do to start troubleshooting this issue? Thanks.
