I am on Ubuntu 20.04 (Kernel: 5.4.0-42-generic) and have been experiencing high CPU usage (30-40%); even when I'm just looking at my desktop without any applications open in the background.
I have recently made two changes to my system:
- Upgraded RAM (Previously had 4GB, added an 8GB stick)
- Installed Windows 10 (Dual-Boot)
And I believe it is after I dual-booted windows I'm facing this issue. I can hear my fans all cranked up, this wasn't an issue before.
I also updated the BIOS after installing windows, maybe that is the cause of the issue?
