Description of problem: When SDDM should show up, it doesn't; there's only a white screen without cursor, buttons or anything else. I can only login my user typing <Ctrl+Alt+F2> Version-Release number of selected component (if applicable): How reproducible: Using SDDM. Steps to Reproduce: 1. Start computer. 2. Wait for SDDM to start. Actual results: White screen. Expected results: A screen with a theme or another that allows me to login. Additional info: Using Hawaii theme, installing via DNF.
Probably a theming issue, triaging to hawaii A workaround in the meantime would be to use some other (non-problematic) theme
A temporary workaround is to install the hawaii-shell package. Until I split it up and move the components into a subpackage.
I'll try both workaround (other theme & hawaii shell) and add the output.

I am experiencing the "white screen" problem with a bare installation of the Fedora 23 KDE spin (which I assume uses plasma shell). I was able to logon on another virtual terminal. I applied all available updates and installed sddm-themes. The problem persists whether using the default sddm theme or any of the alternatives by editing /etc/sddm.conf. I installed kdm and switched to it (systemctl stop sddm;systemctl disable sddm; systemctl enable kdm; systemct start kdm), rebooted and was able to logon and do useful work. I tested sddm-greeter (sddm-greeter --test --theme /usr/share/sddm/themes/maui). I tried all the themes successfully in a terminal after logging on using kdm as the display manager. I have a IBM ThinkPad T42P laptop running Fedora 22 which I successfully switched to sddm. Both are running sddm-0.13.0-4. When comparing the processes on the two machines the failing one (fedora 23) has an extra process with the USER sddm. Its running "dbus-launch -autolaunch ...... --binary-syntax --close-stderr". The "......" is a long string of hex. The sddm-greeter process is missing on the god machine because I have logged on. The rest of the processes commands are the same except for the sockets. On the failing machine (Fedora 23 KDE spin) the last message in the journal (journalctl -b -u sddm) is : sddm-helper[1473] pam_unix(sddm-greeter:session): session opened for user sddm by (uid=0). I can use kdm so Fedora 23 the machine is usable, but it does not restore the previous session after a restart. That is a different bug. Not sure if sddm will fix that but first I need to get past the sddm logon. Looking for things to try to find out where the problem is.
I am on 32bit I686 hardware not 64bit like the original filer of this bug.
Just tinkering with the white screen, clicked on a few places on the screen to see if anything happened. When I clicked on the upper right the screen went black and the machine powered off. Stranger and stranger. Repeated with more rigorous clicks and only the upper right corner causes the power off. Very repeatable. There is a message from sddm-greeter "QOpenGLShader: could not create shader" repeated 6 time in the log well before I clicked. After a reboot and once again getting the white screen I examined the log (journalctl -b -1).The first message was systemd-logind[646]: System is powering down. A few messages later was sddm[875]: Error from greeter session: "Process Crashed" sddm[875]: Auth:sddm-helper crashed (exit code 15) sddm[875]: Error from greeter session: "Process crashed" sddm[875]: Auth: sddm-helper exited with 15 .... sddm[875]: Signal received: SIGTERM

@Brian Kaye: seems a completely different issue.
@Sylvia: did you try updating to see if it's fixed?
@Pier: I can't check if it's fixed because 1) System Settings hangs when I click on the SDDM section to set it, using Plasma. If I'm using Cinnamon it doesn't hangs but... 2) I can't pick an image as background for SDDM, it only shows folder but no pictures (in folders full of them). So I cannot say if it's fixed or not.
Fixed with latest version.
