Description of problem: User list not shown when switching users. Version-Release number of selected component (if applicable): GDM 3.16.2 with xorg-x11-server-Xwayland-1.17.2-2.fc22.x86_64 How reproducible: 99% Steps to Reproduce: 1. Log in user #1 using gdm 2. Log in user #2 using switch user command (gnome-shell upper left next to logout option, do _not_ logout user #1 ) User-list is shown by gdm allowing a second user login 3. Give switch user command again. 4. Two users are logged in, user-list should be shown by gdm 5. Check in as either loggedin user again 6. Give switch user command again. 7. Two users are logged in, user-list should be shown by gdm Actual results: - Sometimes (if not always) a blank screen is shown instead of the user list. - the expected user-list login prompt can be accessed by pressing ctrl-alt-F1 - user #1 screensaver/login prompt can be accessed by pressing ctrl-alt-F2 - user #2 screensaver/login prompt can be accessed by pressing ctrl-alt-F3 Expected results: - Automatically show user list that exists on X11 console under ctrl-alt-F1 Additional info: - This bug is a regression bug. It has been in Fedora before and has been fixed. - I suspect this bug has reappeared as an attempt to eliminate screen flicker at logout and/or switch users. The bug I suspect was attempted to fix would be a xorg bug? (But that is just a guess, possibly bug 1033953) This bug is however a GDM bug? whowatch dump: (gdm-session-w kersti tty2 :0 /usr/libexec/gdm-x-session --run-script gnome-session (gdm-session-w kisandst tty3 :1 /usr/libexec/gdm-x-session --run-script gnome-session (systemd) kisandst pts/0 :1 /usr/libexec/gdm-x-session --run-script gnome-session (systemd) kisandst pts/1 :1 /usr/libexec/gdm-x-session --run-script gnome-session
I'm having the same problem again with gdm-3.16.3-1.fc22.x86_64 xorg-x11-server-Xwayland-1.17.2-2.fc22.x86_64 gnome-shell-3.16.3-1.fc22.x86_64 When switching to another user (with two users constantly logged in) the user select screen (on ctrl-alt-F1) is completely blank. The symptoms are inconsistent. Sometimes right after a reboot teh system seems to work as expected. I hadn't seen the bug for a while now.

The problem seems to reoccur constantly when a third user has been logged in via GDM. That is when three users have been logged in simultaneously.
This is a puzzling bug. Sometimes the system seems to work. I have a new hint though. It seems to have something to do with gnome-shell, in particular gnome-panel. With the screensaver on one of the users had gnome panel visible and functional. I suspect this has something to do with one of the panel extensions. Not quite sure which.
