You have been subscribed to a public bug: If you attach an external monitor to a laptop while Ubuntu is running, always makes the image of the screen look bad on both the internal and the external monitor. I have two command attached to keyboard shortcuts which sometimes can make the computer usable again, if you switch back and forth between the internal and external monitor with:
xrandr --output LVDS1 --off --output VGA1 --auto #switch on the internal monitor, external off xrandr --output LVDS1 --auto --output VGA1 --off #external on, internal off The success seem to depend on what programs are running at the moment of running those commands. If you only have a terminal opened it goes fine, but with Libreoffice and Firefox you need to restart Ubuntu. Attached are three screenshots which all show the screen looks like when the external monitor is attached.
