    Virtualbox | Host&Guest: Ubuntu | How to set guest resolution higher than 800*600

    I have Ubuntu Hardy running in a virtualbox. Guest additions are installed. My only problem is that I can't manage to get the resolution hight than 800*600.

    Anyone knows how to do this?

    same problem here (ubuntu and kubuntu 8.04) I have a 1024x768 monitor. In kubuntu I was able to get 1024x786 to work by switching from 'plug n play' to generic "LCD Panel 1024x768' but this stopped working as soon as I installed the guest additions.

    If your referring to manually editing xorg.conf I have tried this a few times now and have not gotten it to work yet. Thanks though

    Ok I got mine to work with guest additions installed for the first time but unfortunately im not sure what i did. I have reconfigured xorg a few times using
    Code:
    sudo dpkg-reconfigure xserver-xorg -phigh
    And then added in 'vboxvideo' as the driver for the 'configured video device' section. It deffinately did not work for me at first when I installed the guest additions and only before when I changed the configured monitor to to LCD Panel 1024x768.

    sorry I don't know more good luck

    Here's my xorg.conf

    Code:
    # xorg.conf (X.Org X Window System server configuration file)
    #
    # This file was generated by dexconf, the Debian X Configuration tool, using
    # values from the debconf database.
    #
    # Edit this file with caution, and see the xorg.conf manual page.
    # (Type "man xorg.conf" at the shell prompt.)
    #
    # This file is automatically updated on xserver-xorg package upgrades *only*
    # if it has not been modified since the last upgrade of the xserver-xorg
    # package.
    #
    # If you have edited this file but would like it to be automatically updated
    # again, run the following command:
    #   sudo dpkg-reconfigure -phigh xserver-xorg

    This is assuming you have the virtualbox additions installed (mouse and video drivers)
