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). - Change the following parameters:
GRUB_CMDLINE_LINUX="video=AxB-C" GRUB_GFXMODE=AxBxC GRUB_GFXPAYLOAD_LINUX=keep Example: GRUB_CMDLINE_LINUX="video=1152x864-32" GRUB_GFXMODE=1152x864x32 GRUB_GFXPAYLOAD_LINUX=keep
- Now run these two commands one-by-one:
sudo update-grub2 sudo reboot
You should now see your VM's console in the custom resolution that you just set.
