SUMMARY
My laptop's screen does not turn off when the lid is closed. I've set it up to
lock screen when lid is closed via the Power Management config. It used to also
turn off the screen before the 6.3.0 update, but it not longer works now.
Additionally, when I'm connected to an external monitor via a dock, the screen
switches to laptop screen when the lid is closed. It returns to the external
screen when lid is opened again.
STEPS TO REPRODUCE
1. Close lid of laptop.
2. Can see some light leaking if I squint.
3. Opening lid confirms that the screen was always on.
OBSERVED RESULT
Screen stays on when lid is closed.
EXPECTED RESULT
Screen should turn off.
SOFTWARE/OS VERSIONS
Linux/KDE Plasma:
KDE Plasma Version: 6.3.0
KDE Frameworks Version: 6.10.0
Qt Version: 6.8.2
ADDITIONAL INFORMATION
My laptop is an AMD Framework 13, and I'm connecting to an LG monitor via an
UGREEN dock. I can fix it by using the attached acpi script, but I think it
should just work by itself.
