I absolutely love Zorin's GUI, but am totally frustrated trying to get my GPU to properly work. I have an ATI Radeon 560, which is a decent card. However, I HAVE to use nomodeset in grub to get in. I have tried amdgpu but it doesn't seem to do anything. As a result, I'm only getting software rendering and none of the hardware acceleration that comes with the card. My computer is usable, but video is choppy, and even just web scrolling is not smooth. I'm going out of my mind, here.
Yeah, it's not using your card. It says you logged into Wayland, try log into Xorg. You do that by logging out and click your username, a cog should appear here you can choose Xorg/X11. Try test it under it.
Then back to Wayland. You mention you tried to install the driver (which is not needed as the driver is now open source), which can cause the oh no screen.
When you get back on Wayland, uninstall the downloaded driver. Then we'll start on scratch.
I am sorry, I was not very clear.
I asked if you installed it and which method you used in order to try to trace backward what the issue is.
Generally, GnuLinux includes AMD drivers with the Kernel - you should not have to install AMD drivers, at all.
But.
AMD is a funny animal where Proprietary is concerned.
So, let's say you visit the Official AMD Website and download AMDGPU and then install that; it may actually not work.
If installing the package on GnuLinux, I usually recommend:
sudo apt install amdgpu amdgpu-dkms
In order to run this command (This applies to Nvidia, as well), the user must first uninstall/Remove all previous driver installs.
I have seen this comment in a lot of places--that no drivers should need to be installed. Still, I'm positive the GPU isn't being used to its potential and the CPU is doing the heavy lifting. I am at a loss.
I finally got it fixed. After scouring the web for hours and hours, I finally learned I needed to roll back the kernel to 5.15 with mainline. Did that and...poof! Fixed!
Thanks to all of you for your help troubleshooting!
