    Amdgpu Segmentation fault


      I'm struggling to get my fresh Ubuntu installation (16.04.3 LTS) working with amdgpu-pro. I have a NVIDIA gpu installed at PCI port 1 for which I haven't installed any drivers. My screen is connected to that card. Now I've installed an AMD RX 470 card to PCI port 2 and installed the amdgpu package following the installation instructions provided here: Installation Instructions for amdgpu Pro / amdgpu All Open Graphics Stacks .


      Sadly after a reboot Xorg doesn't start anymore. I'm getting the following error message:

      I've googled a lot and found many similar issues but none of the threads provided an answer on how to fix this. Can someone help me out? Thank you!!!

        • Re: Amdgpu Segmentation fault

          Hi bmayer,


          Are you using an EPYC platform? Try installing it with these additional parameters:


          amdgpu-install --opencl=legacy --headless


          Please let me know if that works for you.

            • Re: Amdgpu Segmentation fault



              As of today I am experiencing a segfault in the exact same function tho under a different use case.


              It repros with both the most recent amd linux distributions





              I grabbed 18.40 with the profound hope that the problem was fixed. NOPE! :-(

              Further data points:


              1. This is what my app reports on startup:


                   Xlib:  extension "DRI2" missing on display ":0".

                   screen 0 does not appear to be DRI2 capable

                   Xlib:  extension "DRI2" missing on display ":0".

                   screen 0 does not appear to be DRI2 capable

                   amdgpu_device_initialize: amdgpu_get_auth (1) failed (-1)

                   Segmentation fault (core dumped) <- this is the stacktrace in gdb in my previous post.


              2. I have 2 GPUs on this hp z40 workstation:


                  AMD RX 580                                <- which is selected as my bootup graphics card on my hp z40 workstation's bios settings menu

                  NVidia GK104GL Quadro K5000 <- which is what i am doing compute work on.
