High CPU usage due to Cinnamon desktop environment - restart with pkill
I noticed that a Cinnamon process was using a lot of CPU whenever I moved the cursor with my laptop’s touchpad. That’s definitely not normal. I restarted the process and the problem seems to have gone away.
The process in question was started with the command
cinnamon --replace, so to restart it I just did:
pkill -HUP -f "cinnamon --replace"
-f match the full name of the process.
-HUP signal the process to reload.
