Latest gdm update breaks my Cinnamon desktop

Hadrien Grasland
Hi all,

After installing the latest gdm update from 20180116 ( gdm 3.26.2.1-2.1
-> 3.26.2.1-3.1 ), I cannot login to my cinnamon-based desktop. The
system displays a black screen for a while, then shows a garbled Gtk
dialog with the message "Could not update /home/<my
user>/.ICEauthority". I thus had to rollback and lock this update for
now. Before that, I tried to have a look at the logs, but wasn't sure
what to look for and didn't find anything particularly interesting from
a quick skim.

If I understand SuSE's version numbering scheme correctly, this is a
distribution-specific update and not an upstream one. Can someone point
me towards some kind of changelog or patch diff for this update, so that
I can investigate further what could be causing this breakage?

Cheers,
Hadrien

That was the change from https://build.opensuse.org/request/show/563686
 then.

Can you please file a bug so this can be investigated properly?

Cheers

Looking around, I found an existing bug where someone already sorted out
what is going on: https://bugzilla.opensuse.org/show_bug.cgi?id=1076745

Basically, the GDM update alters /etc/pam.d/gdm in a way that breaks
automount of encrypted home directories (the relevant pam modules are
not invoked anymore).

I'll join the conversation there.

Cheers,
Hadrien
