Today I upgraded to Maverick, and tried to watch a movie with smplayer. After a while I stopped the movie and noticed that I could not use my mouse anymore. No left click ,just middle and right clicks worked and I could not grab the focus of any window. This happened with VLC too, but does not happen with mplayer. I can only fix it whit logout/login. Anyone faced this problem too?
I found the bug which coses my problem https://bugs.launchpad.net/ubuntu/maverick/+source/xserver-xorg-input-evdev/+bug/636311 Ohh and by the way its not related to Qt and upgrading xserver-xorg-input-evdev from the xorg-edgers ppa fixed my problem.
