Public bug reported: Binary package hint: xserver-xorg
I'm running an up-to-date intrepid developer build and found the following bug: When running with compiz enabled and when i start the gnome-screensaver the gnome-screensaver-dialog does not come up. - I don't regain access to my desktop (screen stays blank) if i kill the gnome-screensaver (remotely using an ssh login) - I don't regain access to my desktop (screen stays blank) if i kill compiz (remotely using an ssh login) I cannot kill X with 'killall Xorg' (usually does work) only killall -11 Xorg (segfault) seems to work. I've attached an strace of Xorg just before I start the screensaver with a key combination. The 1st input is me trying to get the gnome-screensaver-dialog with hitting some keys on the keyboard, 2nd i try it with mouse actions (move+left-click) then i try to kill Xorg with killall Xorg and after that I kill it with a -11.
