 Posted: Sun Apr 13, 2025 4:15 pm Post subject: SDDM Does Not Show Up 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: |
[General]
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: | | (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!  |

Apr. 27, 2025 Update
********************
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#override.conf_and_wayland_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: | | 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:

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.  |

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: |
Id=seat0
ActiveSession=3
CanTTY=yes
CanGraphical=yes
Sessions=3
IdleHint=no
IdleSinceHint=1745896453000000
IdleSinceHintMonotonic=143914189
|
For ls -l /dev/tty1
| Code: |
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! |
