How to run HyperV base Ubuntu VM full screen


After I installed Ubuntu Desktop in HyperV I could not get the machine to run full screen.


Update your /etc/default/grub settings.


  1. Start terminal
  2. Type
    sudo vi /etc/default/grub
  3. Press i to enter edit mode
  4. Change the GRUB_CMDLINE_LINUX_DEFAULT=”quiet splash” line to GRUB_CMDLINE_LINUX_DEFAULT=”quiet splash video=hyperv_fb:1920x1080”
  5. Type :wq to save the file
  6. Run
    sudo update-grub

Restart your VM, enter Full Screen mode and enjoy.

  • Any idea why it would fail if instead I used ”quiet splash video=hyperv_fb:1920x1200”?
    That is actually the native resolution for my monitor (a Dell E2211H)...
    • yes, the max resolution that hyperv_fb is supporting is 1920x1080.
    • had the same error, the problem seems to be, that grub supports 1920x1080 as max resolution.
  • I tried this. no effect.  ubuntu opens in  small window and stays that way in full screen mode in hyperv
    Any other suggestions
    • yep, hyperv is not ment to use vm as desktop machines, better to use some remote desktop thingy instead.
