Re: SDDM don't go

"TypeError: Cannot read property of null".  Is there something wrong with the .qml files?

Re: SDDM don't go

There is absolutely no way you could get the log you posted if you don't have that dir. What did you change between your two posts?

Re: SDDM don't go

This

apr 05 19:13:57 legion_of_arches sddm-greeter[839]: QXcbConnection: XCB error: 148 (Unknown), sequence: 179, resource id: 0, major code: 140 (Unknown), minor code: 20

hints at an issue with X. Please do the following:

1. List all the information on your graphics stack (lspci etc.)
2. Post your xorg configuration (if have configured anything)
3. Disable SDDM and try starting KDE via `startx`. Does is work?
4. If you have applied any themes: Remove them and try enabling SDDM again. Does it work?

2. I don't have modified xorg.conf
3. If I disable sddm, with startx plasma goes
4. I don't have applied no theme

currently I use startx for start plasma and sddm is disable

Re: SDDM don't go

Ok, let's get over it again, because in the meantime I have uninstalled and reinstalled sddm once or twice. Currently I have sddm install and is service on systemd is active.
This is journal log
