Hmm, after writing a script which continously attaches strace to gnome- session (and keeping it running in the background), the bug gets worse:
- It happens much more often - After hitting CTRL-ALT-BS, gnome-session goes to D-State in ps -aux, I have to reboot to get an X session again... - strace (running in a screen) does no longer react to CTRL-C or SIGTERM. Thus, the trace does not look very useful, the last lines always seem to stall at fd 27 (which seems to be the socket under /tmp/.ICE-Unix/<pidof gnome-session>) -- Unable to start applications after hibernation https://launchpad.net/bugs/49221 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
