Changing Screen Resolution of Ubuntu on VirtualBox

Filed under: Uncategorized — Zhixian @ 23:08:10 pm

Identify the resolution that your VirtualBox environment supports.

Reboot the system and hit ‘c’ when the grub windows appears appears to access grub console. In grub console, enter the following command to see a list of resolutions (eg, 1024x768x32):

grub> vbeinfo

Edit the grub configuration file
/etc/default/grub. Uncomment the following line in the file.

GRUB_GFXMODE=1152x864x32

Replace the resolution with the one appropriate for your environment.

Save the file. Then update your grub configuration by running:

$ update-grub

Restart your virtual machine again
