I have experienced problems when installing two monitors in Ubuntu. Following script will help you to solve this problem.  I had problems when saving below values so I created a script and put it to the startup.   #!/bin/sh xrandr --output VGA-0 --mode 1920x1080 --pos 1280x0 --rotate normal --output DVI-I-1 --off --output DVI-I-0 --mode 1280x1024 --pos 0x0 --rotate normal --output HDMI-0 --off
