Title:
GUI hangs often
Status in “lightdm” package in Ubuntu:
New
Bug description:
I am using a Radeon HD 7950 with the latest fglrx beta (catalyst
13.3). The problem, however, even happens with fglrx in Ubuntu
repositories. It seems most likely to occur when I am opening a lot of
windows too rapidly, although it is completely random. It is
guaranteed that at some point in time the GUI will freeze. However, I
have noticed that it does not freeze if not being used (I can safely
go AFK for 12 hours and come back to a responsive GUI). The only fix
is to move to a different tty session, sudo killall lightdm, then sudo
lightdm and log back in.
Update: I seem to be able to force it to hang by clicking and holding
down the mouse button on the Unity launch bar.
