Comment 14 for bug 808677

I have tested a bit more:

1) external display works fine as it is supposed when I plug in it first time. After reboot doesn't work even when I boot without it and plug in it back. I have to delete the file .config/monitors.xml after booting and plug in the display to start it working.

Anyway it is better than it was before. At least it works somehow.

2) everything works noticeably slower when both displays are enabled. After I disabled notebook's display it works at acceptable level.
