How to configure 2 AMD graphic cards in Kubuntu

[obuntu91]

Hello,
I recently moved to Kubuntu from Windows where I had 2 AMD graphic cards R9 270X and HD7870 that where managed by AMD catalyst. How can I utilize both graphic cards in Kubuntu?

Thanks for your help

i am not sure it will work. this would actually be a question for AMD support.

assuming both cards use AMDGPU driver then perhaps there is a switch.

and here: https://wiki.archlinux.org/index.php/AMDGPU

look slike AMDGPU-pro might be needed if it's supported.

• ​Supported
  
  • APIs:
    
    • OpenCL™1.2
    • Vulkan™ 1.0
    • VDPAU/VAAPI
  
  
• Basic display features
• Basic power management features
  
  • Note: AMD does not perform QA validation for S4 (hibernation) function as it is highly platform dependent.
  
  
• KMS (Kernel Mode Setting) and ADF (Atomic Display Framework) support
• GPL compliant kernel module
• AMD FirePro™ Features (EDID Management and 30-bit color) -->> is this the feature?
• FreeSync support (Please refer to this FAQ for more information)
• DirectGMA for OpenGL
• Install script and native packages for all supported operating systems
