Some time ago I had problems with the screen resolution of my laptop that ended up solving in a not very correct way, then I have realized that I cannot adjust the screen brightness and that I cannot run complex graphics (games), since the My GPU drivers do not exist in the Linux kernel version 5.4, this because my GPU is from Q2 2020, I was investigating thoroughly and in several forums it is said that Vega GPUs need at least version 5.7 of linux for work properly, I tried to update the kernel to version 5.6,5.7, 5.8, 5.10 and 5.11 and none have allowed me to start Zorin.
I have tried to disable / enable the secure boot without apparent result, it should be noted that for both cases I tried with and without the APIC parameter, I did the same with both versions of the Zorin kernel, 5.4.77 and 5.4.6
I also installed the private AMD drivers without success, once installed I could not boot Zorin, I tried several times to make sure it was not a bad installation. I tried about 5 times
