Bug ID: 468106

Screenshot
I ran into a state in which my new ThinkPad P1 Gen5's fan remained at max speed
for over an hour, even though System Monitor showed a total CPU utilization of
under 9% throughout this time. Running htop showed that `nvidia-powerd` was
roasting the CPU. "Show: All processes" was checked. Choosing "Show: System
Processes", `nvidia-powerd` was shown as taking up only 5% of the CPU.
Maybe this is technically correct if only one core was running at 100% and 5%
was an average across all core, but this isn't what interests the user. I was
using System Monitor to find out what was causing the fan to stay on, and a
process at 5% is easy to overlook and not suspect as the culprit. htop's output
was more useful.
In other instances (may post a screenshot later), the total memory of the
running apps from the Applications tab seemed to be under 4GB, yet my 16GB
system was thrashing the swap file. Whatever system components were using the
other ~12GB, should be shown, ideally with an option to kill them.
