Re: Stuck on reached graphical interface

I think the gpu is too old for the amdgpu driver. Try to add nomodeset kernel parameter in the grub menu.

Re: Stuck on reached graphical interface

There're actually two GPUs, on radeon (norther island so only option) and one amdgpu.
Adding "nomodeset" would result in using the simpledrm device (software emulation) but regardless whether it's the ABI breaking xorg-server update or the server has a hard time keeping AMD GPUs and drivers apart, the modesetting driver should™ work.
If not we'd have to see the full Xorg log.

To stress that: don't use nomodeset, that's under no circumstances a "solution" to anything.
