Public bug reported: Hi,
This bug appears right after upgrading to Quantal. Lightdm works well, but when I try to login, a console screen with a lot of text is openned, then the Lightdm screen reappears immediately. I thus cannot open my session graphically in Quantal (while I never expererienced such thing in Precise). Note that there is no problem when I try to connect in console mode (via tty1 for instance). What is strange about this is that I *can* open a graphical session as guest. Maybe it's not because of Lightdm, but of some configuration file I have. I used Gnome-shell before the upgrade, but it keeped crashing: do you thing this is because Gnome-Shell crashes at launch? When I try to run “gnome-shell --replace” on a guest session (which is on Unity but default), I get a screen with window, but no window manager seems to be there (is that even possible?): I cannot interact with other window than the one I focus into, and I cannot change such a focus… If that can help, here is a bug report of another problem I encountered while upgrading: https://bugs.launchpad.net/ubuntu/+source/ubuntu- release-upgrader/+bug/1059231 . Maybe it's linked? Shall I report a bug against Gnome-Shell rather than Lightdm? If it really is Gnome-shell that cause this bug, it would be nice from Lightdm to display a message informing that the window manager crashed, so that we can report a bug directly against it ;-) Hoping it can help, Martin.
