I'm trying to install amdgpu according to the instructions found here: https://amdgpu-install.readthedocs.io/en/latest/install-installing.html

Running the command: sudo amdgpu-install --usecase=workstation --accept-eula

gives the following error:

The following packages have unmet dependencies:
 amdgpu-pro : Depends: libgl1-amdgpu-pro-ext but it is not going to be installed

I am trying to install amdgpu because my second monitor is undetected and it seems that I don't actually have a driver installed as my output for sudo lshw -c video is:

*-display UNCLAIMED       
   description: VGA compatible controller
   product: Advanced Micro Devices, Inc. [AMD/ATI]
   vendor: Advanced Micro Devices, Inc. [AMD/ATI]
   physical id: 0
   bus info: pci@0000:2f:00.0
   version: c1
   width: 64 bits
   clock: 33MHz
   capabilities: pm pciexpress msi vga_controller bus_master cap_list
   configuration: latency=0
   resources: memory:d0000000-dfffffff memory:e0000000-e01fffff ioport:e000(size=256) memory:fcd00000-fcdfffff memory:fce00000-fce1ffff

I would expect the driver to be listed by configuration if there was one installed.

Does anyone have any ideas on how to fix this? Thanks.

The solution simply installing libgl1-amdgpu-pro-ext.

sudo apt-get install libgl1-amdgpu-pro-ext
