Summary: External LCD monitor slightly wiggles Product: DRI Version: XOrg CVS Platform: x86 (IA32) OS/Version: Linux (All) Status: NEW Severity: normal Priority: medium Component: DRM/Radeon AssignedTo: dri-devel@lists.freedesktop.org ReportedBy: prijatelj.mp3@gmail.com
DESCRIPTION: picture on LCD monitor is like if it would shake very fast but very little. It's watchable but I don't think it's not healty for my eyes. This can be noticed already from boot where daemons are being loaded or when the picture comes on external LCD. I've also noticed that from time to time (it happened to me now about 3 times) this slightly wiggling thing becomes very agressive and it's on both screens. Or if I don't have external LCD it's only seen on laptop's screen. It's so agressive I'see parts, many parts of pictures covering between itself and shaking very fast.I'm forced to reboot computer since not even restarting X helps. Maybe this has something to do with slightly wiggles thing on monitor or no, I don't know.
SYSTEM: - GPU: Mobility X1400 - distro: Archlinux, - kernel: kernel 2.6.36.2-1 - X.Org: 1.9.2 - xf86-video-ati: 6.13.2-2 - KMS (YES)
I've tried to add radeon.disp_priority=2 but the problem is the same. I've tried to add radeon.new_pll=0 but the problem is the same. I've also tried to disable KMS with radeon.nomodeset=0 but after it I'm not able to get into X.
