Power management and touchpad issues.

I installed this setup on a laptop and It had many issues but the main one is the brightness problem. As there is no way to adjust it manually I tried increasing it with "xrandr" from the terminal and set it max. But it still feels pretty dim when compared to the manjaro that is dual booted on the same system. Oh and what is the 11% button it seems like brightness control but can't make it work. The other issue I'm facing is that the touch pad tap to click functionality won't work properly, I have to switch it off and then switch it back on every single time I restart my system.

Just installed it on a laptop and love it. Also here no power management. I get an error: "The Power Management Service appears not to be running" .
Executing: /usr/lib/x86_64-linux-gnu/libexec/org_kde_powerdevil gets the both kde powermanager and touchpad working. Also the status bar indicator is working after starting powerdevil. Seems the systemd script is not executed or failing from /usr/lib/systemd/user/plasma-powerdevil-service.
Also looking for a good way to manage the processor power settings from kde.

Thanks for the support man. But unfortunately Executing: /usr/lib/x86_64-linux-gnu/libexec/org_kde_powerdevil didn't work for me. It trowed a bunch of errors such as "org.kde.powerdevil: org.kde.powerdevil.chargethresholdhelper.getthreshold failed .... " and "org.kde.powerdevil: Handle button events action could not check for screen configuration".

Solved Touchpad issue
I had to add Option "Tapping" "True" to the entry MatchIsTouchpad in the file /usr/share/X11/xorg.conf.d/40-libinput.conf.

It will be like this:

Section "InputClass"
        Identifier "libinput touchpad catchall"
        MatchIsTouchpad "on"
        Option "Tapping" "True"
        MatchDevicePath "/dev/input/event*"
        Driver "libinput"
EndSection

Ooh and I too love this setup.
