Hello everybody, trying to install the amdgpu-pro 18.30-641594 driver on Ubuntu linux 18.04.1 using the '--px' switch for switchable amd graphics results in an "E: Unable to locate package xserver-xorg-video-modesetting-amdgpu-pro" The package is missing from the linux ubuntu versions amdgpu-pro 18.20 / 18.30, while it was present in 17.x
The same is still true for amdgpu-pro version 18.40-x Would somebody with ties to AMD comment on this? Is it just an obsolete feature which is not supposed to work? Removing the paragraph from the current amdgpu-pro documentation would clarify the matter then. Regards,
Sorry, I thought I responded to this already. PX is not supported on the PRO driver anymore. It seems we forgot to put in a deprecated message in the docs. I'll try make note of it for future releases. We recommend using the all open driver for mobile uses and using PRIME for switchable gfx. You can install the all open driver by running the "./amdgpu-install" script with no parameters. If you need vulkan, install the package "vulkan-amdgpu" after the driver is installed. If you need to know to use PRIME, there's a good resource on the ARCH Linux wiki: https://wiki.archlinux.org/index.php/PRIME
Thank you, that clears the situation. I am aware of using the all-open variant using PRIME, and indeed it does work quite nicely. What about OpenCl though? Can you get away using the all-open driver and just installing the opencl part via --headless? Would you be able to access both graphic cards via OpenCl? Regards,
You can add the --opencl parameter to the all open install as well. For example: ./amdgpu-install --opencl=pal This would install the all open stack plus the OpenCL stack for Vega onwards. The OpenCL stack is separate, so it should work over either variant. I'll discuss with the team and add some clarification w.r.t. openCL in the documentation. As for PX, I added a note about the deprecation in the docs, but it didn't quite make the 18.50 release posted yesterday. It should be available in newer builds. Thanks for the bug report!
Thank's for your clarification! That will help with setting things up properly. Regards,
