Binary package hint: xserver-xorg-video-ati
There seems to be a problem with the Ubuntu ATI driver and my ATI Radeon 9800 SE card. When I boot Ubuntu 9.10 (installed on HDD) or Ubuntu 10.04 (beta 2 from CD) certain elements of the desktop contain artifacts (see screenshot "visual_effects_disabled.png"). If I enable in System > Appearance > Visual Effects the amount of artifacts increases dramatically and cover the desktop completely (see screenshot "visual_effects_enabled.png").
This is what lspci tells me:
01:00.0 VGA compatible controller: ATI Technologies Inc R350 AH [Radeon 9800]
01:00.1 Display controller: ATI Technologies Inc Radeon R350 [Radeon 9800] (Secondary)
I'm happy to assist further investigations!
