Plasmashell process is writing to disk - system nonresponsive

Help
1

Hello Everyone,

New here, with a problem.

Many times, but not always, when I login, the plasmashell process is continuously writing to disk at about 70MiB/s.
While the system is doing this the desktop response is about half minutes to two minutes before anything happens, virtually unusable.
Once an application started the response within the app is normal.
I have recently updated to Kububntu 24.04 LTS.

This is my system:
Operating System: Kubuntu 24.04
KDE Plasma Version: 5.27.11
KDE Frameworks Version: 5.115.0
Qt Version: 5.15.13
Kernel Version: 6.8.0-49-generic (64-bit)
Graphics Platform: X11
Processors: 6 × Intel® Core™ i5-8500 CPU @ 3.00GHz
Memory: 7.6 GiB of RAM
Graphics Processor: Mesa Intel® UHD Graphics 630
Manufacturer: Acer
Product Name: Veriton X6660G

Thanks for the help, Peter

Hi! Right after you boot up and the system becomes more responsive, it might be helpful to check your system journal (logs) for messages written by plasmashell since you booted up the system, for example using journalctl --identifier=plasmashell --boot=0.

Some messages and minor warnings are normal, but if something is explicitly going wrong in that process and in turn causing all that disk activity, then there might be a lead provided in that output. (Are you able to see if CPU activity is also unusually high during that unresponsive time?)
