AMD GPU driver install #23

Closed mahboobkarimian closed 3 years ago

Problem: I've downloaded the official amd-gpu driver for Ubuntu from the AMD website (amdgpu-pro-20.20-1098277-ubuntu-20.04) and wanted to install it on my Macbook Pro 2019. With ./amdgpu-install -y --no-dkms it is working, Bu now I can not connect to tan external monitor anymore (can not be recognized by ubuntu). however for ./amdgpu-pro-install we can not use no-dkms option. I want pro-install to enable AMD VCE for encoding via Handbrake: https://handbrake.fr/docs/en/latest/technical/video-vce.html Using the latter command, I am getting this error.

More info: When installing amdgpu-core_*.deb amdgpu-dkms_*.deb we are getting this error:

Looking at /var/lib/dkms/amdgpu/5.6.0.15-1098277/build/make.log:

What we can do to use this driver?

Hi, I think that the issue is:

ERROR (dkms apport): kernel package linux-headers-5.7.19-mbp is not supported
Error! Bad return status for module build on kernel: 5.7.19-mbp (x86_64)

But you can try following: https://math.dartmouth.edu/~sarunas/amdgpu.html I've use it some time ago before I got a NVIDIA card.
