    Re: flickering screen

    Since 2.6.32.16 I don't have to add i915.modeset=0 anymore, the flickering seems to be fixed.

    Now I've got a new problem. When I boot, sometimes gdm loads, and sometimes it doesn't. Switching to tty1 and back to tty7 shows gdm. It's exactly this bug: https://bugs.launchpad.net/ubuntu/+s...ux/+bug/523027

    So I checked if kms is actually running:


    Code:
    jochem@jochem-laptop:~$ dmesg | grep drm
    [   23.286764] [drm] Initialized drm 1.1.0 20060810
    [   23.389012] [drm] set up 63M of stolen space
    [   24.208318] fb0: inteldrmfb frame buffer device
    [   24.212740] [drm] Initialized i915 1.6.0 20080730 for 0000:00:02.0 on minor 0
    [   40.308142] [drm:drm_mode_getfb] *ERROR* invalid framebuffer id
    Anyone knows whats wrong?

    EDIT:
    After updating, it seems to be fixed

    Good job Canonical!

    I'm wondering if the flickering has anything to do with this bug.

    Try dimming the screen and see if it makes a difference.

    Re: flickering screen

    I have an Acer 1410 and have experienced severe flickering with Lucid Lynx. After posting a bug report with Xorg, it was suggested that a client might be responsible ... and I tracked it down to gnome-settings-daemon. Killing it immediately cleans everything up. Running it immediately sends everything straight to hell, with top reporting Xorg eats ~77% of CPU (this is a dual-core Celeron).
