Description of problem:

gdm crashes right after showing up in the boot sequence.
if manually started afterwards in the command line it works fine.

How reproducible:

reboot system, wait for gdm to show up, 1 second later it crashes.
maybe hardware dependent:
lenovo thinkpad t450s, Intel Core i7-5600U,
switching to inteldrmfb from EFI VGA.

Comment 1 Milan Bouchet-Valat 2015-06-22 08:17:49 UTC 
I'm experiencing the same bug with an up-to-date F22 (Intel i915 driver, FWIW). I've found the same report against Arch: 
https://bugs.archlinux.org/task/44588

That report indicated that downgrading to GDM 3.16.0.1 fixes the problem. So I built that version on Koji, and indeed that fixes it.

If you want to install it, it's available from here:
http://koji.fedoraproject.org/koji/taskinfo?taskID=10175976
Comment 2 Milan Bouchet-Valat 2016-01-14 13:25:56 UTC 
In my case, this bug came from a .rpmnew D-Bus file under /etc which I didn't take into account (see upstream report for details). Tentatively closing, but please reopen if you still experience it.
