SDDM Does Not Show Up After Logging Out

Message

Updated on May 31, 2025

I updated my SDDM to 0.21.0_p20250502, problem solved. SDDM on Wayland works after logging out.

********************

As depicted above, my SDDM doesn't show up after I logged out from Plasma when it should be.

After that, running rc-status, I can see that the service "display-manager" in the default runlevel was marked as "crashed". I did have elogind in boot runlevel, and I altered my /etc/conf.d/display-manager to have it to invoke SDDM.

This is my runlevel configuration, "display-manager" was illustrated as "started" when I power on my laptop normally and log in.

******************************

Additionally, I have created a /etc/sddm.conf.d/10-wayland.conf to have SDDM start in Wayland session.

Code: Select all

DisplayServer=wayland
GreeterEnvironment=QT_WAYLAND_SHELL_INTEGRATION=layer-shell

[Wayland]
CompositorCommand=kwin_wayland --drm --no-lockscreen --no-global-shortcuts --locale1

******************************

It seems that SDDM will try to start for multiple times, but it failed.

The log shows

Code: Select all

(EE) HELPER: Failed to take control of "/dev/tty1" ("root"): Operation not permitted

, could it be the reason?

Is there anything wrong with my configuration? Please point it out.

If you need more logs or configurations, please name it.

Any response will be appreciated!

********************

It turns out that this is an issue about user space SDDM login.

As you can see in my log, I was using SDDM on Wayland to login, which was done by adding a configuration file for SDDM according to the Wiki.
https://wiki.gentoo.org/wiki/SDDM#overr ... yland_mode

Doing so results in this problem.

Also, when I try to use SDDM on a root-less X11 session, it also fails to pop up after logging out.

This log:

Code: Select all

Failed to take control of "/dev/tty1" ("root"): Operation not permitted

indicates that it fails to use a user space session to open a login window.

********************

To deal with this issue, simply remove all the entries about forcing the DisplayServer to use wayland or x11-user.

Is this because of any misconfiguration in my setup or it's just not "stable enough"?

Any response will be appreciated!

I can confirm I have exactly the same issue with sddm as above, however when I try to run sddm with epmty override.conf, it doesn't start at all, in fact I get this in sddm.log:

I've the same problem with it, but no problem without override.conf file.

Occurs after logging out in Plasma just like me or on system start-up?

It's pretty weird, I can have it working without the override.conf for now.

In my case

Code: Select all

# grep -E 'KillUserProcesses|RemoveIPC' /etc/elogind/logind.conf
#KillUserProcesses=no
RemoveIPC=no

KillUserProcesses=yes
RemoveIPC=yes
then reboot

Yes Sir, in fact I do.

Could you please check a few things?
After logging out, run: loginctl show-seat seat0 and and verify if CanMultiSession=yes and Sessions is not empty
Also check the permissions on /dev/tty1 : ls -l /dev/tty1
Could you show the content of your /etc/conf.d/display-manager file, especially the DISPLAYMANAGER=... line?

Hello there!

I edited my /etc/elogind/login.conf as instructed and have it checked in tty.

For loginctl show-seat seat0

Code: Select all

Id=seat0
ActiveSession=3
CanTTY=yes
CanGraphical=yes
Sessions=3
IdleHint=no
IdleSinceHint=1745896453000000
IdleSinceHintMonotonic=143914189

For ls -l /dev/tty1

Code: Select all

crw--w---- 1 root tty 4, 1 Apr 29 11:12 /dev/tty1

In the /etc/conf.d/display-manager, I specified DISPLAYMANAGER to be sddm.

Thanks for the response!
