Ubuntu – plasmashell high CPU usage – KDE Plasma Desktop Environment

cpukdeplasma5Ubuntu

I am currently using the KDE Plasma Desktop Environment and a few seconds after logging in the plasmashell process would end up using more than 80% of the CPU which sometimes leads to lag and high fan speed.

Even after killing and starting the process, it would sometimes lower the usage for a while but in most cases there would be no changes.

This does not occur with other desktop environments but I would prefer to stick with KDE Plasma.

I am currently using an:

  • Intel Inspiron 5758
  • 8 GB RAM
  • Intel Core i7-5500U CPU @ 2.40 GHz
  • GPU: Intel HD Graphics 5500
  • Ubuntu 17.10
  • Kernel: 4.13.0-21
  • KDE Plasma 5.9

I have tried:

  • Restarting plasmashell
  • Removing all widgets/applets
  • Disabling ipv6 network capabilities

Is there any solutions for this?

There are many bug reports about plasmashell using high CPU, most of the times the reason for it is some bugged/stuck widget or applet try removing/disabling them. However it can be caused by other things, its pretty hard to say what cause your problem without more information and investigation.
