I already said this, but I think I should stress it again: it's not the actual act of rebooting/shutting down/etc that causes the freeze, it's the chooser window.
The computer freezes even if I try to cancel the shut-down. In contrast, "sudo shutdown -[r|h] now" works. I'm frustrated because I have no idea where to look for more diagnostics. I tried (from a console) listing the processes before and after the window is displayed and I saw no relevant changes. I don't know who owns that window, is it the panel? ** Also affects: gnome-panel (Ubuntu) Importance: Undecided Status: Unconfirmed -- shutdown window freezes everytime https://launchpad.net/bugs/88015 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
