Public bug reported:
Hi
I'm testing kubuntu 20.4 with my HP spectre x360 13 aw0720nz.
The hotkeys to adjust the backlight brightness do not work.
It's no bug in KDE, as adjusting the brightness editing the file brightness in
/sys/class/backlight/intel_backlight doesn't work either.
At /etc/default/grub I already added "acpi_backlight=vendor"
Regards Daniel
