Hi felix, i do not really think its the same, but i have had a couple of month problems after dup ing tw with black console. (sddm) here the problem was a smaller screensize inside grub commandline as monitor native use. (at the moment i have not dup to latest tw) before that update this line was always working fine for me: old resolution (for boot) was: video=1920x1200 showopts but in graphical session and monitor used: video=2560x1600 showopts after changing it everything worked again as it should again. simoN Am 11.03.19 um 02:34 schrieb Felix Miata:

Today is not the first time getting black screens trying to use Plasma's app menu. KDM and XDM
KDM is not a default, SSDM is. Try that.
We've been through this more than once. KDM was long ago deprecated, but still AFAIK SDDM and LightDM continue to omit required optionS I use, so are locked out until such time as one of them restores KDM functionality or KDM disappears from the mirrors. If the latter happens, I'll more likely switch to TDM or KDM3 if they still exist. I like the "unthemed" (aka default) greeter, much, more than any themed greeter I've ever glanced upon.
Besides that, my most used test installation "runlevel" is multi-user, frequently starting and stopping startx sessions, mousing as little as practical. KDM is mainly used when I need to confirm behavior between the two session startup types does not produce different behavior in the X sessions.
I suppose this may be a case where one of SDM or LightDM might be appropriate as a sort of bisect process, but no way am I going to switch more than temporarily. Also I was trying to do something else with this box https://bugzilla.opensuse.org/show_bug.cgi?id=1118689 and this diversion is apparently tangled with my attempts to follow up with it.
I installed sddm anyway. All its greeter text except time/date is ridiculously small. Its time format is wrong. It flashes junk on the screen when I move the mouse, then blanks everything except time/date. It lists users who aren't allowed to login, omits the one needed, and offers no place to type username in manually.
startx -- :1 produced black screen instead of working Plasma, and no mouse clicking was helpful. Ctrl-Alt-BS shut the PC down.
When I keep my default vga=791 video=1440x900@60 on cmdline to boot (inconsistent with what's needed for bug 1118689 follow up, neither), sddm screen is pure black, no mouse, no keyboard response, systemctl isolate multi-user adds a cursor to otherwise black vttys, with salvation only via remote login.
