Support, Screen Tearing.

You can try these either on the installed MX (as you did on Grub menu) and the ahs live-session, as boot options:

Code: Select all

radeon.cik_support=0 amdgpu.cik_support=1

or (next trial)

Code: Select all

radeon.si_support=0 amdgpu.si_support=1

First command booted to black screen and the second one booted to desktop.

But it is exactly the same like the last time.

[Huckleberry Finn]

Code: Select all

sudo apt update ; sudo apt install --reinstall xserver-xorg-video-amdgpu -y

If installed successfully, next boot again

Code: Select all

radeon.si_support=0 amdgpu.si_support=1

[dada666]

Done, now what?

[Huckleberry Finn]

Reboot with

Code: Select all

radeon.si_support=0 amdgpu.si_support=1

You can again create:

Code: Select all

sudo tee /etc/X11/xorg.conf.d/20-amdgpu.conf <<!
Section "Device"
     Identifier "AMD"
     Driver "amdgpu"
EndSection
!

(In case of blackscreen we'll delete or rename to .old)

[dada666]

Boots to black screen, and my monitor turns off.

[Huckleberry Finn]

Ok, you can delete it on live session (via file manager) or as you did previously at boot Ctrl alt F1

Code: Select all

sudo rm /etc/X11/xorg.conf.d/20-amdgpu.conf

Meanwhile, on some places it's mentioned that, that card was not supported by AMD.. that may be the reason it does not load the driver(s).. Only one: https://community.amd.com/thread/215489

[dada666]

So, I can't use linux?

[Huckleberry Finn]

You can.. just with the Vesa driver it's already using..

(Though it looks it's supported with kernels you tried: https://linux-hardware.org/index.php?id ... -1462-3050 )
