kernel@kernel-EP43-UD3L:~$ sudo apt-get install linux-headers-generic build-essential cdbs fakeroot dh-make debhelper debconf libstdc++6 dkms libqtgui4 wget execstack libelfg0 dh-modaliases
[sudo] password for kernel:

Package libqtgui4 is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'libqtgui4' has no installation candidate
E: Unable to locate package libelfg0

I get an error,what can i do for resolve it?

Solution

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.

Darktable

sudo apt install darktable

sudo darktable-cltest

git clone https://kernel.googlesource.com/pub/scm/linux/kernel/git/firmware/linux-firmware.git

sudo cp ~/linux-firmware/amdgpu/* /lib/firmware/amdgpu && sudo update-initramfs -k all -u -v
