--- Comment #5 from Piotr Mierzwinski <piotr.mierzwin...@gmail.com> --- I use Antergos, which became the Arch Linux. I turn on my PC, login into my user and after some time I use "Switch User" option. Now trying back to currently working session (because I changed my mind) on login screen I click into my self and try to login. In result Plasma started loading again, and in the middle just stop (any black screen doesn't happen). I just kill it by Ctrl+Alt+Backspace. To be able to back to my session I need to actual switch to another user, and then I can back to my session. And then I get proper screen with button "switch to this session" (or something similar). I hope now is more clear. Anyway I relogin myself trying to retest new updated configuration. I added suggested parameter to both mentioned configuration files. Like this: /etc/sddm.conf [Theme] CursorTheme=Adwaita [X11] EnableHiDPI=false reuseSession=true /etc/sddm.conf.d/kde_settings.conf [Autologin] Relogin=false Session= User= [General] HaltCommand=/usr/bin/systemctl poweroff RebootCommand=/usr/bin/systemctl reboot reuseSession=true [Theme] Current=charlie [X11] EnableHiDPI=true [XDisplay] # Xsetup script path # A script to execute when starting the display server DisplayCommand=/usr/share/sddm/scripts/Xsetup [Users] MaximumUid=60000 MinimumUid=1000 reuseSession=true Unfortunately it changed nothing. Again after I used "Switch User" I got normal sddm login screen and when I chose my self then Plasma again started loading. I use sddm in version 0.18.1 -- You are receiving this mail because: You are watching all bug changes.
