           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 at lists.freedesktop.org
        ReportedBy: prijatelj.mp3 at gmail.com

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.

- GPU: Mobility X1400
- distro: Archlinux, 
- kernel: kernel
- X.Org: 1.9.2
- xf86-video-ati: 6.13.2-2

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.
