First, it begins right away. I log in and I usually I can't drag the
teamviewer window that starts automatically. Probably I have similar feeling:
To me, it feels a bit like some invisible window was put over the whole screen, or some application "captured" the mouse and didn't release it, but thats only speculation ;-)
Sometimes after pressing Ctrl-Alt-Del it starts working for a while. Also, I usually can't switch between tasks using keyboard (Alt-Tab). But it all starts working after I switch the terminal: Ctrl-Alt-F1, Ctrl-Alt-F7.
ubuntu-13.04, that I've recently installed on two machines. On the other one everything's fine. I'm using
Logitech diNovo Edge keyboard and
Mad Catz R.A.T. 7 mouse. I've tried reinstalling
xserver-xorg-input-all, to no purpose.
