Hello. I was hoping someone could help me adjust the screen resolution size. I have installed Trisquel Mini using VirtualBox on Mac OS X. Everything installed perfectly. However, I cannot seem to figure out how to adjust my screen resolution. Current resolution I am guessing is 640x480 or 800x600.

The only fully libre solution for increasing screen resolution with VirtualBox is to edit GRUB, so that the boot resolution is increased. You will probably have to stick with a 4:3 resolution though.

Thank you Calinou. In case anyone else wants to know how to do this by editing the grub file, here are the steps below:

Step 1: find the preferred mode

  • Reboot and press and hold shift to display your grub. Press C to enter console mode.
  • Type vbeinfo
  • Review the different resolution options available and note the one you want to use.
  • Press ESC to return to grub and press Enter to boot.

Step 2: Setting the resolution in grub

  • In terminal and type sudo nano /etc/default/grub and find the line

    #GRUB_GFXMODE=###x### (Could say 640x480, 800x600, etc.)

  • remove the # and change to the resolution you noted prior.

    e.g. GRUB_GFXMODE=1200x800

  • save, then type sudo update-grub

And that's all there is to it. Problem solved.
