Title:
gdm crashed with SIGSEGV in g_main_context_dispatch()
Status in gdm package in Ubuntu:
New
Bug description:
Problem 1: When logging out of a user account, gdm presents the gray
screen with the top bar, but no greeter. The system is locked up, no
cursor. Can't even bring up a VT. The only time I see the greeter is
once, at boot.
Problem 2: Tried to log in with the Wayland Gnome session, but the
screen just flickered and came back to the greeter. So I tried the
regular Gnome session, resulting in a black screen. This time I was
able to get a VT, from which I restarted gdm. This time I was able to
log in to the regular Gnome session, but with the error message you
see.
