No Dynamic Screen Resolution

Discussion in 'Linux Guest OS Discussion' started by terrapin, Apr 6, 2012.

  1. Hi all,

    I'm running PD 7.0 on a late 2009 13" MBP. I installed Ubuntu 11.04 by choosing Ubuntu from the new VM dialog in Parallels, then upgraded to 11.1 after install.

    I then installed Parallels Tools, no problems were reported and Parallels reports that the Tools are up to date. However, I cannot seem to enable dynamic screen resolution. It seems to be stuck in a small size, maybe 800 x 600 or 1024 x 768. When I expand the guest window or enter full screen, the resolution doesn't change, text and icons become large and fuzzy.

    I dug around and found that the video driver being used is VESA: Parallels video adapter. Any help is much appreciated. Thanks

    Have you tried editing your xorg.conf file?
  3. Thanks dpickett, what should I edit in the xorg.conf?

    Try changing the setting in modes to the resolution you want. I run my VM at full screen, so my Modes line is:
    Modes      "1920x1080"
