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?

thanks!

  • 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 07 '18 at 22:38
  • hi dobey - added the output you wanted. – zen Mar 08 '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 08 '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 09 '18 at 10:47
  • hi dobey - this page seems to suggest the HD 7800 series cards are supported by the amdgpu pro driver? https://support.amd.com/en-us/kb-articles/Pages/AMDGPU-PRO-Driver-for-Linux-Release-Notes.aspx – zen Mar 13 '18 at 23:44
  • It suggests it is supported by the _pro_ driver, yes. You may be able to [blacklist](https://askubuntu.com/questions/938658/how-to-blacklist-radeon-module) the _radeon_ driver, to see if _amdgpu_ gets picked up. You may not need to install the pro driver, though I suppose if you want Vulkan, you may need the pro drivers. – dobey Mar 14 '18 at 14:43
