Description Teddy 2019-08-15 21:02:40 UTC 
Operating System: Kubuntu 19.04
KDE Plasma Version: 5.15.4
KDE Frameworks Version: 5.56.0
Qt Version: 5.12.2
Kernel Version: 5.0.0-25-generic
OS Type: 64-bit
Processors: 8 × Intel® Core™ i7-6700HQ CPU @ 2.60GHz
Memory: 15,6 GiB of RAM

After rebooting my notebook, screen brightness is reset to max. Changing screen brightness works with Fn+Up/Down

$ ls /sys/class/backlight/
nvidia_0

$ cat /sys/class/backlight/nvidia_0/max_brightness
100

$ systemsettings5 --version
systemsettings 5.15.4

It's a systemd-backlight problem, probably unrelated to KDE:
