Hello, I made an account just to ask about this, as I have seen one other entry with a similar problem, but it did not help me. I bought a PC with a Radeon RX 6700 (non-XT) and in Windows 11 it works flawlessly.
However, when I try to boot into Linux live USB, there's no output. I can install anyway in the safe graphics mode, but then when I boot, no output. I followed instructions to get the newer amdgpu from Linux Firmware, and that does work but only temporarily. Every time there is a system update, I have to redo the process all over again, which got so annoying that I went back to Windows.
If anyone has any suggestions, I would greatly appreciate the input!
Using DKMS or using the Latest available Zorin OS kernel (Which includes the AMDGPU drivers) should allow the GPU to function normally.
You may however, have a case where the GPU is initializing at the wrong time during Init, resulting in graphics not displaying. You can try using the nomodeset parameter to see if that resolves the issue of a blank screen at boot.
