fedora 28 switch user breaks GDM
For a while now, I have encountered problems with the multi-user environment on fedora. I'm running f28 and gnome shell 3.28.2 on a Dell xps15 2017 9560, using wayland.
If I am logged in normally, then go to the top right corner and select switch user, I can do so (once!) and log in as a different user. If I log out from this user account, I see GDM and want to login as the previous user - I type my password, and GDM hangs.
Now I can hit CTRL+ALT+F2 and then I see the lock screen, where strangely I am able to unlock. But then, successfully unlocked, the system behaves strangely (e.g. display brightness is no longer adjustable). Only a restart can fix this issue.
I believe this can be a problem for less experienced users, If they do not know about the ctrl+alt+f keybinding.
I tried replacing GDM with lightDM, but then I have no lock screen anymore and cannot change users at all (but that is a different issue)
I have the same problem when I try to switch users
Same problem here, it's really annoying, especially when several users of the machine are not really willing to switch using
CTRL+ALT+F<x>. As suggested in an answer here, I will try to add some debugging info and see if someone can help.This is happening on two of my machines running Fedora 28 with the latest upgrades. No Nvidia or Radeon here, my graphics controller is Intel.
Has anyone found a solution to this problem? I have been experiencing the same issue since upgrade to 28. 4 members of my family use my home machine and it is quite annoying to have to reboot anytime a user logs off.
I am having the same issues, I filed a bug: https://bugzilla.redhat.com/show_bug.cgi?id=1601154
The workaround I have been using is to make sure you log off before allowing another user to log in. The issue seems to arise when re-joining an existing graphical session.
I would suggest we all vote for the bug report but I don't seem to see a way to do that.
