Per default ubuntu offers screen resolutions which does not fit for my laptop. My panel allows 1980x1080 but the best fitting choice from ubuntu was 1280x960.

But with some nice commands you could pimp the list of available resolutions:

get the modeline:

cvt 1920 1080

this gives you the hint:

Modeline "1920x1080_60.00"  173.00  1920 2048 2248 2576  1080 1083 1088 1120 -hsync +vsync

extent the list of modelines (cut the suffix from the resolution for a better name):

sudo xrandr --newmode "1920x1080"  173.00  1920 2048 2248 2576  1080 1083 1088 1120 -hsync +vsync

verify the entry:

sudo xrandr –q

add the entry to the list of available resolutions

sudo xrandr --addmode VBOX0 1920x1080

and voila: you could choose the new resolution under settings

# re: Specifying new screen resolutions for ubuntu in a virtual box 11/10/2012 3:56 AM Luke
It works, kind of. I have lubuntu on virtualbox, and I do get 1920x1080 switched on this way, but it jumps right back to 1024x768 if I log out or restart the vm. Just can't get it to save the resolution, and it disappears from the list too, so I have to write all that every time I turn on the vm. :-S

Solution?
