I have installed KDE Neon on a Lenovo Thinkpad Yoga.
Besides some smaller issues everything works fine. But what is annoying for me is, that the indicators for brightness and volume are very unreliable.
While the buttons work everytime, the indicators sometimes work and sometimes not. When they don't work I can make them work, making some settings in the Desktop settings like showing the toolbox or not. But at the latest after a reboot the problem is there again.

Ok, I have found out when it happens:
I have two control bars. If I set both to hide automatically, the indicators don't work anymore until I activate desktop settings.
Now I set one of the bars to windows can cover the bar and now all works fine.
