Keyboard Backlight missing in KDE Neon with Plasma 6.3 beta
SUMMARY
The "Keyboard Backlight" slider is missing from the "Brightness and Color"
widget
STEPS TO REPRODUCE
1. Use a laptop that has an illuminated keyboard
2. Boot KDE Neon (not an already installed distro with Plasma)
2. Open the "Brightness and Color" widget
3. See if the "Keyboard Backlight" slider is there
OBSERVED RESULT
Brightness and Color widget doesn't show the keyboard backlight value / slider
from the beginning.
Meaning already on first boot.
See the attached printscreen!
EXPECTED RESULT
Brightness and Color widget to show the keyboard backlight value / slider from
the beginning.
I heard that this works after a reboot and I can confirm that it seems to have
worked on installed Debian + Plasma 6.2.5, but the problem still remains for
KDE Neon and I assume every other distro with Plasma that is booted in live
mode from a pen drive.
Reboot there is useless and while a logout / login might be enough to solve the
problem, if I forget about the problem at night and already opened a few
programs, maybe Firefox with a few tabs or some form fields, writing something
or some long running commands in the terminal, having to logout to fix the
keyboard lighting is not feasible at all.
As for using live-booted distro with Plasma at night, I've done it quite a few
times so I don't think it's such an edge case.
At least for me, where I booted quite a few times in live mode to solve
problems.
It's not a big problem as for installed distros, it works, but still I hope to
see it fixed for live booting too.
Hopefully the cause of the problem can be identified.
Sorry I could not find an already existing bug report about this!
