If I try to logout the system freezes up. The only way to recover is to power off and do a hard reboot. I’ve tried searching to see if this is a known issue, but could only find one entry on Reddit that goes back to fedora-33; and even at that I couldn’t understand that user’s particular fix.
NOTES:
The very first time I did a user logout it worked fine. It has never worked since then. That first time I did the logout from a Wayland session. Due to several issues with Wayland I have reverted back to using X11; but either way, logout freezes the system in either Wayland or X now.
If I let the timer that appears on the logout screen run down, then it does come back and show me the login screen. However, if I click on the ‘logout’ icon to override the countdown timer then the system immediately freezes.
Invoking ‘Restart’ from the KDE Applications menu works just fine.
When I say ‘freezes the system’ what I see on the screen is the black logout screen with the various options to Shutdown, Logout, Restart; and the Logout option is defaulted with the usual countdown timer running. When I click on ‘Logout’ to override the timer and logout immediately the screen simply freezes there. The counter stops, none of the other buttons are active, keyboard has no effect, etc. Tho I can still move the mouse pointer around.
When I press my PC’s power button it shuts off immediately (suggesting that fedora/KDE has actually logged out and shut down the user session?, it just isn’t showing me the screen to re-login?)
I am running an all Intel desktop PC - with the Intel graphics, no add-on graphics board.
This is a fresh from a disk reformat install of fedora 35, KDE spin approx one month ago.
Good idea - I just did so. Created a new user and did several login / logouts with both the new user and my preexisting user. Result: New user is working fine. Old user still not working.
So that would suggest a corruption, or some configuration conflict, that is specific to one user and not the other.
So for my own purposes I could just use my new user’s account and abandon the old one. Tho inquiring minds may wish to know what is causing the issue.
Thanks for that pointer over to KDE bug reporting. I did find a bug report that seems pretty close to my experience. So I did add my own info to that in hopes the extra bit of info helps them work it out.
It did not shed much light; tho I did see a fatal error as part of the logout process - which I reported back to the KDE Bug you had earlier pointed me to.
And re KSystemLog GUI app - interesting; but I can’t see any way to see more than the last 1000 entries using that. Even when I google it nothing comes up about being able to go back more than the last 1000. Given that the boot up process writes about that many, it therefore isn’t too helpful in looking back at a prior boot’s log. Unless I’m missing something?
I have exactly the same issue on Fedora 35 KDE, after logout, the screen goes black.
However, pressing Ctrl + F4 still allows to open up a terminal and Crtl + F2 shows a frozen login screen where nothing can be clicked, but the mouse moves.
Where did you find the KDE bug report? Could you provide a link?
Per @jroc Note 2. - When I let the time timeout it does not return to the login screen. It hangs with a black screen. I can select areas of the black, but can’t get to a local tty or do anything. The power button powers down the system immediately.
I created a new user - and that user was able to logout sucsessfully over several login/logout cycles with varying ammounts of work between login and logout with bot X11 and Wayland sessions.
What can I try to remove in my normal user then to see if I can replicate the new user’s ability?
I am having this issue with KDE spin.
I took the advice of installing GDM and enabling it for startup, rebooting, logging in and then switching back to SDDM. It worked perfectly.
I was able to log out multiple times without issue. Then I decided to customize my “Application Style”. I switched to Fusion, applied, and then tried to log out. Immediately I was stuck again.
I then enabled GDM, rebooted, logged in, switched back to SDDM, and I am able to log out again.
Interestingly enough I was having a hard time logging out of plasma after switching to GDM too.
I wanted to add that if I do a ctrl-alt-F2 while my machine is plagued with the frozen lockout it shows the initial login screen with my password entered (just the dots). When the machine is not experiencing the freezing, ctrl-alt-f2 just shows a black screen.
