Bug Description
Binary package hint: unity
Just turned on laptop and plugged in external monitor. Compiz crashes and system becomes extremely slow. Graphics are unresponsive and very glitchy, wallpaper displays briefly and then there are lines across the entire screen. Pretty new to Linux (first install) so not sure what this means or what else is required.
