dev/input/event4 AT Translated Set 2 keyboard Last edited by idnael December 7th, 2019 at 01:31 AM. Please tell if you need any more information to help diagnose and solve this problem. This is very annoying because I always expect the computer to be quiet when it is not doing any intensive processing. The fan problem didn't happen, and the sensors command shows that the temperatures never rises above 40☌.

I also tried a live usb installation to boot in Ubuntu 18.04, similar to what I had before the update. The given values are average, and not very precise, but the fan always starting working at regular intervals: The problem persists, but with different times. Since then, I tried other window managers.

The sensors command shows that the temperature is always rising above 50☌ immediatly before the fan starts working: But doesn't seem to be related with the fan. The top command shows the cinnamon process is using around 3% of CPU. Doesn't happen if I only login in the console. This happens after I start a X session, even if I have no application started. Since then, every 40 seconds the fan starts working for 5 seconds and stops.
