Description dutchkind 2020-10-27 13:12:02 UTC 
SUMMARY
When starting Plasma in a Full Wayland session I can edit the touchpad settings. However, when I start Plasma in a Wayland session the touchpad settings tell me no touchpad was found. I discovered that I can change the touchpad settings by first logging into Wayland Full, change them there, and then in Wayland and the same settings are applied there.

Btw, when using Xorg everything works as expected, so there is only a difference between Wayland and Full Wayland

STEPS TO REPRODUCE
1. Start Plasma Wayland
2. Go to touchpad configuration
3. 

OBSERVED RESULT
Greyed out

EXPECTED RESULT
Workable configuration for touchpad

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Opensuse Tumbleweed

Fix call to KWorkSpace::detectPlatform

This sets QT_QPA_PLATFORM, so has to happen before the QApplication is
created.
