Description:
Switching from another tty to gdm makes the system crash, so that it doesn't respond to any input. It does not matter whether you use Ctrl+Alt+F1 or the logout-button of your desktop environment. This happens with Cinnamon, OpenBox and at least for me also with Gnome, although it might not always happen with Gnome. Desktop managers other than gdm seem to work properly (not tested by me).

I'm sure that one of these package updates broke it:
gtk-update-icon-cache 3.18.4-1 (still happens with 3.18.5-1)
gtk3 3.18.4-1 (still happens with 3.18.5-1)
gnome-shell 3.18.2-1
mutter 3.18.2-1

The issue has been confirmed by others on the forum:
https://bbs.archlinux.org/viewtopic.php?id=205035

Additional info:
* package versions
See above, plus:
cinnamon 2.6.13-3
gdm 3.18.0-1


Steps to reproduce:
- Install gdm and Cinnamon
- Use gdm to login to Cinnamon
- Log off again and see the system freeze
This task depends upon

Running it on Wayland (that's the default)?

If it's the default, then yes.

So try it with X. There are already many bug reports around here for GDM on Wayland.

Thanks for the tip. With WaylandEnable=false it indeed works for me. Still, this is just a workaround, not really a fix.

Today's update to
gnome-shell 3.18.3-1
gdm 3.18.2-1
libgdm 3.18.2-1
didn't change anything about the issue.

Right, it's not a fix, but it tells me that this is most likely the same as one of those many other reports. Doesn't respond to input makes it sound like  FS#46835

Similar situation here on Intel Sandybridge. Sometimes (1 in 5 or so, not easy to reproduce)
after logout the screen turns black, but I can connect via SSH and restart via magic keys.

Since disabling Wayland it works fine again.

Didn't find this problem otherwise. It's not  FS#46835 .

Is this still an issue? There have been several new kernels and GNOME releases since this bug was reported.
Comment by Jürgen Feste (jf25) - Friday, 27 October 2017, 20:52 GMT
Well, for me it works now. Neither Wayland nor X cause any trouble.
