install amd driver on ubuntu 20.04
One problem might be that Ubuntu 20 ships with kernel version 5.4. The kernel for your driver is limited to 3.4. Might need a different Ubuntu dist? Or maybe time for a GPU upgrade? Either way, that's probably your main issue.
I've successfully installed AMD drivers on Ubuntu 20.04 for the following cards:
- 5500 XT
- RX Vega 64
I know those cards use a different driver, so adjust the naming convention(s) accordingly. Maybe this will be helpful for someone else.
Let's get a clean install, first.
locate amdgpu-uninstall
Should be /usr/bin/amdgpu-uninstall...run it.
sudo /usr/bin/amdgpu-uninstall
If it fails to delete /opt/amdgpu/ and/or /opt/amdgpu-pro/ directories, then:
sudo rm -rf /opt/amd...
Here is your driver: https://www2.ati.com/drivers/legacy/amd-driver-installer-catalyst-13.1-legacy-linux-x86.x86_64.zip
You'll need to unzip it.
sudo apt-get install unzip
unzip ~/Downloads/amd-driver-installer-catalyst-13.1-legacy-linux-x86.x86_64.zip
./amd-driver-installer-catalyst-13.1-legacy-linux-x86.x86_64.run
Current AMD Driver
Again, wrong kernel, so this is probably moot.
You could try giving a different driver a whirl?
Alternatively: Check here
tar -xvf ~/Downloads/amdgpu-pro-21.30-1290604-ubuntu-20.04.tar.xz
sudo ./amdgpu-pro-21.30-1290604-ubuntu-20.04/amdgpu-install --opencl=pal,legacy,rocr --no-dkms --headless
Groups
Add yourself to render and video groups
sudo usermod -aG render $USER
sudo usermod -aG video $USER
sudo reboot
Changes won't take affect until you reboot.

sudo apt install darktable
sudo darktable-cltest
