You can add missing resolutions to Ubuntu 12.04 using xrandr.

First, use cvt to create a new resolution mode.

sudo cvt 1920 1080 60

Part of the output should be similar to this: "Modeline "1920x1080_60.00" 173.00 1920 2048 2248 2576 1080 1083 1088 1120 -hsync +vsync" (w/o the quotes).

Next, declare a new resolution mode.

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

Next, find out the name of your video device.

sudo xrandr -q

Mine was named "Virtual1" (running a virtual machine). Once you know the name of your device, you can, finally, add your new resolution mode to the device/system.

sudo xrandr --addmode Virtual1 1920x1080_60.00
