Virtual Box – Change console window size

Invertedlight/ April 25, 2018/ OS X Tech Tip/ 0 comments

  1. Identify the resolution that your VirtualBox environment supports.
    • Reboot the system and keep the Shift key till the grub windows appears then hit c.
    • This will drop you into the grub console.
    • Enter the commend vbeinfo to see a list of resolutions.
    • Select the resolution that works for you (in my case, 1024x768x24).
  1. Edit /etc/default/grub to modify/create a line GRUB_GFXMODE=1024x768x24 (where you replace the resolution with the one appropriate for your environment).
  2. Update grub and reboot: sudo update-grub2 && shutdown -r now

After the reboot you should now have the new console screen size showing.
