SUMMARY

Plasma don't show up (panel bar, wallpaper, menu when right clicking on wallpaper, ... but krunner works) when starting on a external screen from a laptop with optimus manager set for Nvidia.

STEPS TO REPRODUCE
1. Connect your laptop with HDMI to an external screen and switch (CMD+P) to external screen only
2. Install Optimus Manager, set as Intel for default and after launching your session switch to Nvidia
3. It closes your session, login then again

OBSERVED RESULT
You will not see your wallpaper, nor your panel until you type "plasmashell --replace" into your krunner

EXPECTED RESULT
You should not have to type "plasmashell --replace"
