I installed Debian 7.2.0 as a guest operating system on VirtualBox 4.2.18 (host OS is Windows 7). I installed Debian without any graphical user interface. When I start up Debian, the console size is awfully small (about 80x40). How could I change that?

1 Answer 1


The resolution of virtual consoles can be set by adding the following lines to /etc/default/grub and then running update-grub (maybe as root):


Just change the 1024x768 to the resolution you want.

  • Is there a way to do this without GRUB? As in, not taking GRUB into account -- when the system has already been booted? Jul 25, 2016 at 15:00
