The server is probably stuck in an infinite loop." https://bugs.freedesktop.org/show_bug.cgi?id=14633 X freezes with Composite and Mouse Wheel, mouse moves, no...

KDE desktop, compiz and all, but I believe it is not > related. > > The symptom: system boots up regularly, I do regular work, and after a random > amount of time, X freezes. If compiz is on, all I can do is move the mouse > pointer. If compiz is off, even the mouse pointer is frozen. The OS itself is > not, I can ssh from a remote machine and read logs.
