[SOLVED] On current kde can't logoff user

gordydawg · 01-13-2022, 05:41 PM

I would like to add to Franklin's comment regarding slow logout and occasional hangup while logging out in sddm. I have been seeing this same issue when choosing to log out back to the sddm screen. When logout hangs up, sddm-auth** and sddm--0:** files remain behind in tmp.

As for causes, I have little to offer. But a few observations; unlike Kde4, graphical login in kd5 has been supplied by sddm. Sddm does not seem to be well tested and integrated compared to prior kde apps. The sddm developers are SystemD** orientated and their work appears to not play well with non-SystemD stuff such as with elogin, pam and other modules. Hence the older version packaged in Slackware.

Sometimes 'fixed' during current updates to KDE, but reappearing once again. Sigh

**I recall an old blog post by Alienbob on his first attempts at creating kde5 packages for current. Issues at the time with sddm not playing well in a non systemD environment. And more telling was the snobby attitude and reply from the sddm developers 'Our SystemD way or the highway' Shades of the Poettering syndrome.

I can confirm that, so far at least, the OP's solution seems to have worked. I know nothing about PAM so I have no idea if there's any downside to this.

While I don't observe crashes, I am experiencing slow logout issue on the latest Slackware64-current in Plasma.
There is a problem though because I have Slackware64-current installed on the host and as VM client. While host has issue with the slow logout (including shutdown/reboot), VM client does not have this problem. Both systems are identically configured with the exception of simulated hardware in VM of course.
So I don't think that this is going to be a easy fix as it looks like slow logout occurrence is somewhat random.

In my case, I do not use sddm. I boot to runlevel 3 and use startx (as a user, not root) to start the KDE Plasma Desktop. I frequently get slow log outs. When the log out is slow, it almost always results in a hang at this point on logging out:

Code:

startx
xauth:  file /home/chris/.serverauth.19603 does not exist

No keyboard response, only why to reboot is hard reset (ugly) or log in via ssh from another computer or my cell phone and issue a reboot command.
