[Bug 864010] Re: lightdm segfault in libglib after xorg segfault
Some more information.
I can reproduce the crash always in the following way:
1) Boot the machine.
2) Log in to KDE. Everything works, including 3d effects.
3) Log out of KDE. KDM starts.
4) Log back in -> X crashes, KDM restarts immediately.
5) Log in again -> KDE disables 3d effects and allows logging in.
Sometimes if I try to enable effects after 5), I can crash X again. But
that does not happen every time.
It also might be relevant that I can reproduce the crash on both my
desktop machine and my laptop, both of which are running Oneiric and
both of which have Intel integrated graphics. I have not seen similar
behavior with my work desktop, which has discrete nVidia graphics.

Title:
lightdm segfault in libglib after xorg segfault
Status in “lightdm” package in Ubuntu:
Incomplete
Status in “xorg-server” package in Ubuntu:
Incomplete
Bug description:
After typing my password into the new greeter I was given a black screen with just the pointer
at midcentre; which wouldn't move.
dmesg shows:
[ 274.801957] show_signal_msg: 21 callbacks suppressed
[ 274.801966] lightdm[1025]: segfault at ffffffff022be720 ip 00007fee2a0822de sp 00007fee27966af0 error 4 in libglib-2.0.so.0.3000.0[7fee29ffd000+f4000]

[ 275.034456] [drm:drm_mode_getfb] *ERROR* invalid framebuffer id
There is no X server running, looking at /var/log/Xorg.0.log it ends
with:
[ 288.858] (II) intel(0): EDID vendor "SEC", prod id 13875
[ 288.858] (II) intel(0): Printing DDC gathered Modelines:

so doesn't look like it seg'd.
There is no /var/crash entry (even though apport is enabled)
I did notice (after a successful restart of lightdm and login - so maybe this is the next instance):
/var/log/lightdm/x-0.log had:
