    I know everyone has been having issues with screen resolution in 3094 with Linux distros, I know I have. I think I may have found a workaround for now..

    If I step down the bit depth to 16 bit (instead of 24 bit) resolution I am able to get any resolutions I want. I use the following command line to setup everything instead of manually editting xorg.conf for resolution. You do have to edit it to change bit depth.

    sudo dpkg-reconfigure -phigh xserver.conf

    Stepping through this and then editting xorg.conf to choose the 16 bit resolution and now I can get any resolution in any distro I want.

    Hope this helps,
    Peter

    Hmmm, i'm able to switch to 1280x800 but not to 1440x900 which is my MBP's native resolution. I also tried 8 bit mode but that didn't work either.

    So it's a fix for macbooks ;) or are you able to switch to higher resolutions?

    Confirmed on Fedora 6, with a MacBook Pro.

    /etc/X11/xorg.conf :

    Section "Screen"
    Identifier "Screen0"
    Device "Videocard0"
    DefaultDepth 16
    SubSection "Display"
    Viewport 0 0
    Modes "1680x1050"
    EndSubSection​
    EndSection

    Bart,
    Did you use dpkg to reconfigure the screen res? Make sure that the 1440x900 is the first entry in your mode line as well.
    I'm able to get 1440x900 on my MBP (switching to full screen and configuring that res in my corg.conf)
    Strange! It is working for me on my CD MBP, don't know about the C2D model.

    Cheers,
    Peter

    1440x900 works now, i'm unable to switch to any other resolution while running X11 but i guess that's just broken in this beta. Thanks for help.

    Bart, were you able to switch before with Ctrl Alt +/- or xvidtune? I can set any resolution I like with 24bit color, but cannot switch on the fly.
