Bug Description
Hey everyone,
after resolving some of the problems I got after upgrading to 20.04 [1] I'm now using my Lenovo X1 Extreme Gen 2 with the thunderbolt docking station (and an HDMI monitor attached).
Everything worked out of the box, except for the increased general heat of the system (constantly over 70 °C) and the consequent concert of fans that makes working aside the (closed) laptop almost impossible.
It is really hard to understand if there's a specific process causing the CPU to be so constantly stressed, and what is more curious is that monitoring the general status of the system resources (CPU, Memory and so on) there are no peaks, it shows a normal usage, which is what I do: browser, mail, and some console. Something I would expect that with 16 cpu and 32 gigs of RAM should not be a concern.
Both thermald and tlp services are obviously installed and running.

The first problem I can see is that this machine is using the 'intel' graphics driver for the Intel GPU. That's a mistake as it's an old driver. The Intel GPU should be using the 'modeset' driver. Please remove the 'intel' driver from your Xorg config files and/or just uninstall the package 'xserver- xorg-video- intel' and reboot.
If the heat problem still persists then next please run 'top' to confirm which process is using the most CPU.
