Just a note, may or may not apply.
I discovered the motherboard for my Ryzen 7 2700u will only allow the kernel access to the amdgpu bios if MX is booted up using UEFI mode - a legacy boot produces an error in dmesg about no amdgpu BIOS found and reverts to the radeon driver.
Thank you all for the hints. After enabling buster ahs in MX Repo Manger, new drivers installed:

P.S. I've tested "tearfree option" in MX Tweak, started MX AHS live USB (older kernel), but no effect. These was the origin issue, installing MX first time with this AMD CPU+GPU.
But the issue still exists, high CPU load watching fullscreen video. I think "renderer: llvmpipe" should be replaced by "AMD RAVEN" like the one, when booting with MX live from USB. But it seems you are right, booting MX in Legacy BIOS mode, not in UEFI, switch amdgpu.dc=1 will not be activated. Unfortunately, I've installed in Legacy mode.. :(
Code: Select all
$ ls /sys/firmware/efi
ls: cannot access '/sys/firmware/efi': No such file or directory
Found a (debian) solution
https://blog.getreu.net/projects/legacy-to-uefi-boot/ to switch from Legacy to UEFI.
But I plan to use this case to check my backup/restore.. I will plan next time install MX with UEFI from scratch and restore my data. Will inform you about success about AMDGPU. Thanks all!
