Starting with Linux 4.16.2, when I logoff from KDE Plasma, I don’t get back into SDDM (just a black screen) or back into LightDM (wild random blocky screen, see attachment). I have a RX 580, DC is on. Same result on Linux 4.17rc2. Distro is Antergos/Arch. Monitor is connected via DP. Using SDDM, I can press ctrl + alt + F1 etc. to theoretically get to a tty prompt but the screen does stay black. But then, after pressing ctrl + alt + del numerous times, at least my system does a proper reboot. In LightDM, this does not work and I have to use the reset button. Worked with Linux 4.16.1 before.
