How to run HyperV base Ubuntu VM full screen

Problem:

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

Solution:

Update your /etc/default/grub settings.

Explanation:

  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.

      yep, hyperv is not ment to use vm as desktop machines, better to use some remote desktop thingy instead.
