Comment 15 for bug 661450

Today I have noticed some other behaviour, when hooking to laptop to lcd projector. The laptop resolution is 1366x768 and the projector is 1024x768, and immediately after connecting the cable i saw an extended destop background on the projector, but was not able to put mirror of the picture. After many tries with ARandR I succeeded, but later I was not able to disconnect the second screen even after unplugging the cable, it was as if some invisible layer was in front of the desktop and I was not able to click with the mouse on any gui component. Task switching was working with alt+tab and keyboard was working to type commands but I just could not click on them.
