So I deinstalled 5.13 and installed 5.10. But it still doesn’t work, also installed the free driver you gave me but still didn’t work. I think I will reinstall with the new and updated version.
I feel really sorry and dumb. The version I installed was a bit older and buggy. So I flashed my usb with the newest version and then installed it. Worked, now I am 5.15, should I use it ore change to 5.16 ore to 5.10?
And also how can I apply an ICC profile file that I got for my monitor? Because without it is really bad.
It now works and thank you all for the help. Learned a lot new thing. Also thanks stephane for your help.
Stay on 5.15, do not install other kernels that are not LTS. Keep your system up to date too, do not hold updates for long time so there is no issue to update.
For color profiles, it seems there is colord-kde that should be able to help. Install it and try.
First, why GIT? There is the package in the Manjaro repositories.
Also after I installed it for testing, and rebooted, it seems it is easily accessible by searching for Color in the Application menu (Color Correction).
sudo pacman -S colord-kde
After reboot, go to System Settings → Hardware → Color Corrections
