I'm slightly worried you might be hitting multiple different bugs there. But instead of worrying, maybe just try the 'modesetting' driver. It might solve even more problems if you get both GPUs using the same driver: Section "OutputClass" Identifier "Use Modesetting" MatchDriver "radeon|amdgpu" Driver "modesetting" EndSection I'm not sure why those drivers don't yet prefer "modesetting" by default because in Wayland sessions that's exactly what happens anyway. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1923153 Title: [radeon] Display output laggy from iGPU when operating on desktop with attaching AMD R7 430 graphic (dGPU) To manage notifications about this bug go to: https://bugs.launchpad.net/oem-priority/+bug/1923153/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Hi Daniel, Thanks for sharing comment#27. Let me summarize the reproduce scenarios in Intel + AMD case. 1. Boot from iGPU -> switch to dGPU -> switch back to iGPU -> iGPU lag. 2. Boot from iGPU -> connect secondary monitor to dGPU -> remove 1st monitor from iGPU -> dGPU lag. 3. Boot from iGPU -> connect secondary monitor to dGPU -> set iGPU as primary display -> moving an application (e.g. glxgear) from secondary display (dGPU) to primary display (iGPU) -> iGPU lag.

The other finding for comment#20. If connecting two monitors then there is a way to reproduce it. 1. Set iGPU as primary monitor 2. Run an application from secondary display (dGPU) (e.g. glxgear) 3.
