[SOLVED] x11-misc/sddm-0.18.1-r3 behaves like a window

Hello everyone!

I'm having problems with sddm: when starting the system everything goes fine, but if I do a user logout I have sddm as a window (with buttons to maximize, minimize and close) that prevents me from logging back into the desktop.

This all happened after an update of several qt libraries.

Does anyone have a similar problem?

I appreciate any help!

Thanks!

Hello, majoron!

Thanks for the tip of the topic, I will follow, because I have a problem with kwin if I try to login again.

Me too. When I first boot up Gentoo I can log in fine. But if I log out, I can't log in again. Kwin-x11 causes a segmentation fault, and the sddm login screen disappears. Neither sddm nor kwin have been recompiled recently, so I also suspect a qt component (recompiled on 1 June). I tried to log in to a Wayland session, and that wouldn't work, either. When I have some time, I'll try xfce.

I also tried killing sddm from the tty1 screen. I can kill it, but when I try to start it again, it dies. The login screen appears, briefly, then disappears.

So I just logged out of my Plasma session. Kwin crashed when I did so. I was able to log in to XFCE. I get an error message from kwin now and again, but otherwise things seem to be OK. I'll experiment some more, then file a bug report.

Hello, davidbryant!

I also suspect qt libraries cause this problem, but when trying to downgrade dev-qt/qtwebengine-5.15.2_p20210224 I got compilation error...

If you open a bug, let me know, so I'll follow...

davidbryant · Posted: Fri Jun 04, 2021 3:56 pm Post subject: Temporary Workaround

OK, I figured out how to kill sddm and restart it successfully. So I can work around the logout problem without rebooting the system. But it's almost as much work as rebooting, so it's not a very good workaround.

1. Switch to tty1 (Alt + Ctrl + F1)
2. Log in as root.
3. Say "ps ux | grep sddm"

Hello, davidbryant!

Thanks for the feedback and for having opened the bug, I'm already following it.

I hadn't suspected these programs you talk about, I'll see if I test them downgrade, anything I'll let you know.

When I ran "emerge --deep --update @world" this morning, I got a whole new suite of kde-frameworks / kde-plasma programs. The new version of kwin (kwin-5.21.5) appears to have resolved this problem..

Hello, davidbryant!

The same thing for me here, how nice it was corrected...
