Cool smooth update no hiccups. Last 2 updates been really smooth for me.

Tho do have that annoying occasional few times a day a slight quick flickering of screens.

With this update everything went fine, exept for plasma-shell:

Log file and/or terminal output errors happen all the time, they are usually harmless.
Are getting to the desktop at all?
Please describe in detail what is happening other than just error messages.
Are you sure you received all of the updates?
Just to be sure use this command the terminal:

sudo pacman -Syyu

i have just updated the packages incl. plasma 5.5.2 , everything ran smooth, gave Y to all questions, but after the update i cannot start Plasma Shell. It is just black screen. All other programs are running fine, but just with no desktop.
Thanx

sudo pacman -Syyu

there is nothing to do

So the panel is there?
Was there an error message typed across the desktop?

No, no panel at all, no plasma shell, no panel. just the rest of the apps. No error was typed.

Then plasma shell isn’t crashing then or there would be an error message.
What display drivers are you using?
Also, did you change any settings for the compositor?
Could you please attach your .xsession-errors file.

I am with prop nvidia and didn’t change anythig about the compositor.
Here is the .xsession-errors file http://download.tuxfamily.org/hummer/.xsession-errors

Looks like you had a broken update.
Try reinstalling the plasma-desktop.

 sudo pacma -S plasma-desktop

Thanx a lot. Reinstalling it fixed the problem.

No problem.
