You can have the ubuntu server console in VirtualBox start at a resolution that your graphic card supports via the virtualbox environment.

Quick Steps

  • Check the resolutions your graphic card supports via the VirtualBox Environment (VBE).You should be able to find that out by issuing the command 'vbeinfo' in the GRUB console (hit the C key when the GRUB boot menu shows up).

  • Pick one resolution, then open '/etc/default/grub' (e.g. sudo vim /etc/default/grub) and change the line #GRUB_GFXMODE=640x480 to something like this GRUB_GFXMODE=1152x864 (where 1152x864 should be your custom resolution which is also supported by your graphic card).

  • Now run these two commands one-by-one:

    sudo update-grub
    sudo reboot
    

You should now see your VM's console in the custom resolution that you just set.

(PS: As Javier Rivera said, full screen resolution may not be possible.)
