Trying to run wayland again, but...

[asturm]

If you don't have a Wayland [compositor] session to choose from, then your system likely doesn't have any Wayland [compositor] session file installed. SDDM has nothing to do with that.

[rab0171610]

In addition to what asturm said, SDDM finds its available sessions as .desktop files in /usr/share/wayland-sessions and /usr/share/xsessions.
I have:
/usr/share/wayland-sessions/plasma.desktop
/usr/share/xsessions/plasmax11.desktop
/usr/share Xsession.desktop
These are installed by plasma-login-sessions:

Code: Select all

Found these USE flags for kde-plasma/plasma-login-sessions-6.5.5:
 U I
 + + X       : Install X11 session file for Display Managers (default is Wayland if both enabled)
 + + wayland : Install Wayland session file for Display Managers

The /usr/share/wayland-sessions/plasma.desktop file contains the exec lines:

Code: Select all

Exec=/usr/libexec/plasma-dbus-run-session-if-needed /usr/bin/startplasma-wayland
TryExec=/usr/bin/startplasma-wayland

The file in the exec line, usr/bin/startplasma-wayland , should be installed by kde-plasma/plasma-workspace .
Maybe you have a non-standard Plasma installation or custom/inconsistent use flags.

Code: Select all

/usr/share/wayland-sessions

[MaDDeePee]

its think its my /etc/sddm.conf that is wrong.
could someone post me a working one?

its is modified late 2023 and i commented wayland stuff out or deleted them, for some reason...

Just throw it away.

[MaDDeePee]

Just throw it away.

ok

[asturm]

Did that fix it then? What do you have in /etc/sddm.conf.d/ instead?

lol sorry, I thought it was a joke

I completely deleted /etc/sddm.conf, and surprisingly it didn’t change anything.
SDDM doesn’t recreate it after boot, but the login screen still looks the same as with my old config.

in /etc/sddm.conf.d i got two files:

Code: Select all

cat /etc/sddm.conf.d/01gentoo.conf 
[General]
# Remove qtvirtualkeyboard as InputMethod default
InputMethod=

I don’t see anything Wayland-related there. That’s why I gave up on Wayland a while ago… stupidly.
This system is from 2015, I’ve kept it updated over the years, but maybe I still have some leftover code from early Wayland experiments that’s breaking things now

If that's the case, this may help: https://wiki.gentoo.org/wiki/On_occasional_emptytree

Just keep in mind that you have to go through all the updated config files (/etc etcetera and make sure you merge your original files appropriately.

It will take a while... But it might help.

I've done it when things just wouldn't behave. But I haven't had to do it for a very long time. -DNuq usually does enough.
