I just upgraded from 18.10 to 19.04, and i am facing a tough drop in performance. Fan is spinning really high, and no smooth operation of the gnome-shell possible anymore. Sensors are showing this:

top showing this:

with gnome-shell process continously going up to 95% and dropping again.

On 18.10 on gnome everything was fine. I am running a Lenovo T470s, 20GB of RAM, should not have any issues, should it?

Anyone facing a similar behaviour? Any idea of how to solve this / what is the reason for this?

The answer was posted in comments:

When I unplug my T470s from the Lenovo USB-C-Dock, the temperature of the CPU drops by 30 degrees. The fan gets down to 0 RPM.

replugging the dock seems to not raise up that behaviour again, so it seems like, after finishing the upgrade to 19.04, you will have to replug your machine to the dock, in case you are using one (especially if it is the 40AC0135 from Lenovo)
