I've seen a few other Q&As around this, but nothing that is exactly what I'm experiencing.
I have a new Lenovo X220 which I'm running the latest Kubuntu on. If I close the lid when I open it I get, 9/10 times, a flickering screen which sometimes updates around where the mouse is currently pointing and sometimes draws the wrong thing (i.e. it draws a program which is actually in the background)
Normally I've resorted to just rebooting if this is the case but I want to know if there is a better way of doing it?
