I am running ubuntu 16.04.4 with budgie desktop - I just installed mesa's vulkan drivers, and when I run vulkaninfo, I can see the gpu it uses is my intel ivy bridge igpu instead of my radeon hd 7870. is there a way i can get it to use the proper gpu?


Editing to show the output of lshw -c video like dobey wanted

$ sudo lshw -c video

  • What driver is being used for the radeon card right now? (sudo lshw -c video should show details, if you can edit your question to include that info please) – dobey Mar 7 '18 at 22:38
  • hi dobey - added the output you wanted. – zen Mar 8 '18 at 21:27
  • It looks like the radeon driver is being used. I'm not sure if Vulkan is supported on that driver, or on your card. I'm also not sure if that card is supported by amdgpu driver either. – dobey Mar 8 '18 at 21:51
  • hmm ok - i have tried to install the amdgpu pro drivers with little success - i couldnt log in the last time i tried :( – zen Mar 9 '18 at 10:47
  • hi dobey - this page seems to suggest the HD 7800 series cards are supported by the amdgpu pro driver? support.amd.com/en-us/kb-articles/Pages/… – zen Mar 13 '18 at 23:44
