When I have watched a video online (usualy with YouTube video's), be it with Firefox or Chrome and press the button to exit full-screen mode, my laptop screen turns grey and there seems to be nothing I can do about it but enter TTY2 with ctrlaltf2, login and type sudo restart lightdm and log back in, resulting in loss of work.


I own an ASUS N76VM laptop and it's running Ubuntu 12.04.

Offcourse I don't want this to happen and I'd rather make it so that it doesn't happen; instead of a sollution for after it has happend, but any sollution rather then restarting LightDM would make me happy.

Did you enable Legacy Fullscreen in Compiz Workarounds? – Danatela Apr 9 '14 at 7:12
I downloaded compizconfig, went to workarounds and enabled Legacy Fullscreen. Now we wait... – Nkciy84 Apr 9 '14 at 8:55
@Danatela Nope.. I just watched a video on youtube through Chrome on Ubuntu. Again, after clicking 'exit full screen' the same error occurred again. – Nkciy84 Apr 15 '14 at 6:01
