    Default No 1680x1050 with HD4200 (RV620)

    Hi,

    i have:
    • An onboard Radeon HD4200 (RV620)
    • Kernel 2.6.32
    • xorg-server-1.6.5
    • xf86-video-ati-6.12.4 driver


    If I use smaller resolutions, e.g. 1280x1024 everything works fine.
    If I use the proprietary fglrx driver everything works fine even with the 1680x1050 resolution.

    If I use the Open Source driver with the 1680x1050 resolution, the display starts flickering: It often turns black for about half a second when moving the mouse, typing on the keyboard or the cpu is under load.

    I think dmesg outputdoes not contain anything related to this problem.

    Here are some snippets of the complete Xorg.0.log which might be important:

    I would be thankful for suggestions how to solve this problem or how to analyze it further.

    Oh, and my /etc/X11/xorg.conf is the following:

    Code:
    Section "Module"
            Load  "glx"
            Load  "v4l"
    EndSection
    
    Section "Device"
            Identifier  "Card0"
            Driver      "radeon"
    EndSection

    I had similar problems with an RV710. Only the DVI output would be affected though.
    Setting DisplayPriority to high mitigated the problem somewhat, as did using radeonhd instead of radeon.

    Try radeon from git master. I added new pll code fairly recently that solved a lot of the flickering problems on newer cards.

    Thank you!

    Setting the "DisplayPriority" "HIGH" option reduced the flickering but I still had black screens. (now about every minute)

    Using the latest radeon driver from the git repository solved the problem for me.
