Description Martin Krajnak 2016-09-07 08:55:54 UTC

Description of problem:
gdm was frozen right after start, because of misconfigured /etc/gdm/custom.conf where I had:

[daemon]
AutomaticLoginEnable = true
AutomaticLogin = test

There was no user named test in system. After commenting these lines everything solved the problem but gdm greeter should be shown despite the error in config and there should be no freezes.


Version-Release number of selected component (if applicable):
gdm-3.14.2-18.el7.x86_64

How reproducible:
always

Steps to Reproduce:
1. add user test
2. configure autologin
3. delete user test
4. restart system

Actual results:
System is frozen after gdm starts.

Expected results:
System should show gdm greeter screen or some error message without freezes.

upstream bug has a patch, though, it also points out the patch is less than optimal.

We should probably fix this in 7.4 via rebase than in 7.3

No one hit this issue except QE, so I guess it is save to fix in 7.4.

Comment 3 Ray Strode [halfline] 2016-09-07 14:53:59 UTC

right, it's not a regression or anything, i think it's been a problem since RHEL 3, but at least since RHEL 5.

We should fix it for 7.4 though.

Comment 4 Ray Strode [halfline] 2017-03-10 18:54:58 UTC

okay added the patch from the upstream bug.

Comment 6 Michael Boisvert 2017-05-25 15:12:35 UTC

The solution is pretty good actually. The system automatically logs into a new basic GNOME session that gets your name/username/password during the initial setup. After you complete it, you are logged into your new account.
