I have KDE 5 which worked well since 2 months.

Today it suddenly began holding 100% of one CPU core and won't stop restarting.

Every time when I log in, my taskbar and desktop totally freeze during about 30s then crash down together. Luckily the search application bar and other components are still working.

I saw these two questions :

And tried two methods inside :

killall plasmashell; kstart plasmashell; exit

sudo apt-add-repository ppa:kubuntu-ppa/backports
sudo apt update && sudo apt full-upgrade -y

But it's always not better.

My environment :

Kubuntu 17.10
KDE Plasma 5.12.4
KDE Framework 5.44.0
Qt 5.9.1
Kernel 4.13.0-38-generic

Thanks for your help.

Well I found it.

kstart plasmashell

showed that crash always happened after clipboard widget initialization.

Indeed I've copied a huge text content(~55Mb) just before, which made the klipper widget unable to handle its history in ~/.local/share/klipper/.

By wiping that folder, every thing is back to normal now.

In my special case, I also unchecked this "Save clipboard contents on exit" option since I don't really need it : img
