Hi, I have Acer Nitro 5 AN515-42 (AMD Ryzen 5 2500u + Radeon RX560X).
I am getting high battery drainage in ubuntu 20.04. I have even tried using TLP and Powertop, but efforts nonetheless. There are also many ACPI Issues during boot up.
Issues I am getting during boot up are listed below, please help for both battery consumption and ACPI Issues that are arising due to buggy BIOS.
I tried turning ACPI off by using flag pci="noacpi" but after BIOS 1.18 update, it is running fine without it, but errors still persist

    what is the nitro kernel? It specifically says it is a root-kit and it is trying to give itself root privilege? That sounds suspicious… Usually root kits are malicious software trying to take control of your computer to get sensitive information or lock your computer and force you to pay money to have it unlocked. Can you just uninstall or disable the "nitro" package or the "rtkit-daemon" ?

    As for your battery drain issues, have you installed the proper graphics drivers? it is possible your graphics card is not sleeping properly and always being used instead of your integrated graphics

    The software he uses is: https://github.com/heftig/rtkit . There is no "nitro"-kernel, since nitro is just his hostname.

    Regarding a draining battery, installing powertop is probably a good idea to see what's draining power. The Acer laptop I use uses 12Watt according to some Plasma6 widget during light usage. Someone with a Framework laptop claimed 8W for a device two years ago, which is impressive, but it's probably better optimized for Linux.

    The thread was from 2020, so presumably the OP has either solved his issue already or bought a different laptop.
