*** If you're not sure this is actually a bug, instead post about it at https://discuss.kde.org If you're reporting a crash, attach a backtrace with debug symbols; see https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports *** SUMMARY I use Plasma with BSPWM as my window manager under X11. Under BSPWM logout, shutdown and restart from the application menu or dashboard do not work. I get the semi-transparent overlay that asks me for confirmation, but nothing happens afterwards. The only way I can shut down the machine is by running `sudo poweroff` from a terminal. STEPS TO REPRODUCE I use the following shell script to launch the session (`/usr/local/bin/plasma-bspwm.sh`): #!/bin/sh export KDEWM=/usr/bin/bspwm /usr/bin/startplasma-x11 To register this session I have the following XDG desktop entry file (`/usr/share/xsessions`): [Desktop Entry] Type=XSession Exec=/usr/local/bin/plasma-bspwm.sh TryExec=/usr/bin/startplasma-x11 DesktopNames=KDE Name=Plasma (BSPWM) X-KDE-PluginInfo-Version=5.22.5 SOFTWARE/OS VERSIONS Linux/KDE Plasma: Void Linux (available in About System) KDE Plasma Version: 6.0.4 KDE Frameworks Version: 6.1.0 Qt Version: 6.6.0 ADDITIONAL INFORMATION All these actions work fine when using X11 with KWin or under Wayland, which is why I think that this is a separate issue from 481938. The two services mentioned in https://bugs.kde.org/show_bug.cgi?id=481938#c5 do exist on my system.
I can confirm this happens with other window managers too (in my case Awesome WM on Arch Linux; a Google search also gives results for a thread on Manjaro forum where they've the same problem on i3).
*** This bug has been marked as a duplicate of bug 488853 ***
This is still happening on 6.2.0 for me.
6.2.1 hasn't solved it either. This seems to be a different issue than the purported duplicate anyway because when shutting down (or rebooting, etc) I can still see the wallpaper and invoke a terminal and everything. In the other bug the screen is black and the tty is completely unresponsive.
In my case the wallpaper and all panels are gone, the screen is black, but I can still open a terminal (using Meta + Enter, a key binding I have set up in SXHKD). The window manager remains working, but the Plasma desktop is gone.
I noticed that if I press the power button on my tower the "power" overlay or whatever you call it (the semi-transparent overlay with the "shutdown", "restart" and so on buttons) does come up and the computer gets shut down properly. It's only when when I explicitly click "shutdown", "log out" or "reboot" from the applications menu widget that the problem occurs. In my system settings -> "power management" -> "When power button pressed" I have selected "show logout screen", so this behaviour seems to be wrong as well.
