You didn't read the news item?

[asturm]

What "public domain" is that? This line is only there because you put it there in the first place. Which is not necessary.

Otherwise:

I change DisplayServer to x11 "DisplayServer=x11=x11" and restart

It now started a X daemon but majority is still on wayland

Before upgrade to plasma 6, I didn't set DisplayServer, it automatically startup X.

BTW: I can use startx to startup desktop manually with no issue.

[asturm]

Again.

SDDM is a display manager. It can start whatever desktop environments/sessions your system holds. If you installed kde-plasma/plasma-meta with USE="displaymanager sddm", which is enabled by default, then it is your display manager of choice.

"selecting" is the keyword for doing this in GUI. As we have selected our desktop session of choice for ages. Look in the lower left edge.

[weiypan_us]

I am sure i have selected USE="displaymanager sddm"

Thanks asturm, I think I have got your instruction.

my selection is on top left, probably it is because I put the bar on top instead bottom.

Probably because I use auto login, after upgraded to plasma 6, the first reboot didn't give selection. Instead, it gave me my normal desktop with low resolution.

My first action was get into "system settings" to change resolution. After clicked "Apply" button, screen turned black. Then I started struggle by search solution in public domain.


Because you mentioned "SDDM login screen", deleted all in /etc/sddm.conf.d/ except "DisplayCommand=/etc/sddm/scripts/Xsetup" so it give me a login screen after reboot.

Now it looks good at least with X11.
