Slow to load desktop from login screen

[RealPTR]

Code:

cd /usr/share/kservicetypes5/
sudo ln -s kwinscript.desktop kwin-script.desktop
sudo ln -s kwineffect.desktop kwin-effect.desktop

That speed up the process a bit... a tiny bit... :-) 

That what I thought happened. My system accumulated residue stuff which is stuck in the settings.
