I just installed fedora32 on my computer and my monitor looks too much whiter than windows 10, the color of images is very washed out or desaturated. My video card model is “AMD RX 480.”
To try to find out, I used USB boot manjaro, linux mint and centos workstation as a comparison, and finally found that all operating systems with the new kernel will make the monitor look too bright, only the centos workstation brightness and color is correct.
My question is:
1、how to downgrade the amdgpu driver to an older version?
2、How to disable video card driver updates when updating system.
(There’s a very good tutorial for installing amdgpu pro drivers in the forum, but I’m considering that the drivers used for redhat/centos may cause trouble for future kernel upgrades.)
