I have a similar problem on Gutsy Gibbon (it was all right with Feisty and Edgy).
When I use any "shutdown button" : o the little red botton on the task bar, o the "System/Quit" menu, o the desktop shutdown button, gdm seems to freeze (the only thing I can do is to move the mouse on the screen) for several minutes (4 to 5)... ( ctrl-alt-F1/F7 works fine) ... and the the "popup shutdown window" came to the screen. And effectively, if I cancel this"pop-up window", the next time I activate any shutdown button it works fine (the pop-up came immediately) Version info : ----------------- GDM 2.20.0 xorg : 1:7.2-5ubuntu13(gutsy) -- Xorg freezes on shutdown / restart https://bugs.launchpad.net/bugs/150349 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
