           Summary: Video flickers on X1200 / RS690 over DVI
           Product: Drivers
           Version: 2.5
    Kernel Version: 3.0.0
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: Video(DRI - non Intel)
        AssignedTo: drivers_video-dri@kernel-bugs.osdl.org
        ReportedBy: stephan.diestelhorst@gmail.com
        Regression: No


I still experience flickering on the DVI of my on-board graphics card if I set
the mode to 1920x180 (ragrdless which timing 59.9 / 60 Hz).  Tried both KMS /
UMS, no real difference.  AFAICS, all pathes in other bug reports should be
picked up by now.  It seems that graphics activity (moving a translucent
window) is more prone to blanking the display.

Killing upowerd does not help, so it is not a polling issue.  CPU is is not
properly detected by the BIOS (too old, no upgrade available), so it may (?) be
that some registers (MTRRs?) are not set up properly.

Reducing the resolution does seem to help.

Let's focus on KMS here.

Please attach the dmesg output.

Does radeon.disp_priority=2 help, or forcing a reduced blanking mode?

Tried radeon.disp_priority=2 and video=1920x1080MR@60 and I can still see the
flicker.  Will attach a dmesg.

Closing, since I do not own the hardware in question anymore.
