Black screen after restart

With my old RX 5700 graphics card I was able to use Zorin OS without any problems.

now i have a RX 7700 XT with i5 14400F and wanted to install Zorin os.

No chance. Black screen after restart.

I disabled secure boot, disabled fast boot, disabled TPM, I don't have dual boot with Windows. I have made all updates in zorin OS. Even tried Mesa Updates but absolutely nothing works.

I only have the problem with Zorin OS.

check if the AMDGPU drivers are properly configured.
Open the GRUB configuration during boot (Shift or Esc key).
Edit the boot line by adding:

amdgpu.si_support=1 amdgpu.cik_support=1

Press Ctrl+X to boot with these parameters.

Just wanting to make sure, this is the same system that you had a 5700 in prior and then upgraded the gpu to a 7700 xt? Or is it a whole new system? I currently run a 7900xtx and I double checked, and by default it does indeed function properly.

Hello, unfortunately it didn't work and yes it's the same system

I don't know what the problem is: Every other Linux Distro works for me out of the box but unfortunately nothing works at all with Zorin OS. That's a shame because I would have loved to use Zorin OS.

But from what I can see, I don't seem to be the only one with this problem.

See if this Linux Mint thread helps:

Additionally, is your BIOS up-to-date?
