I’m running Fedora 42 with KDE on my laptop and experiencing an issue when shutting down via the KDE desktop interface.
When I click Shutdown from the KDE menu:
- The screen goes dark.
- However, the power indicator diode stays on, as if the system went into hibernation or sleep.
- I need to press the power button again to fully shut it down.
Observations:
- If I shut down from the terminal using
shutdown now, it works properly. - If I shut down while using the built-in laptop display only , the system powers off correctly.
- If I shut down from the login menu, it works properly
- The issue only occurs when I have an external monitor connected (I’m using USB-C to DisplayPort)
Logs from when the shutdown in GUI is pressed:
