Is there a way to make xorg-server to release eGPU?

2018-11-17 Thread Qu Wenruo
Hi, Recently I got a eGPU closure which contains an RX580. Xorg server detects it and PRIME works mostly fine. However amdgpu kernel module keeps panicing the whole kernel when the eGPU is disconnected, either hot plugged out or using the pci remove sysfs interface. And rmmod amdgpu returns EBU

Scaled output doesn't resume correctly

Confusing parameters for "xrand --setprovideroffloadsink"

2018-12-25 Thread Qu Wenruo
Hi, I'm trying to understand what the parameters of "xrand --setprovideroffloadsink" means. Google/Arch shows a lot of eGPU use cases, where user should just exec "xrandr --setprovideroffloadsink 1 0", to make the secondary GPU to output to the first one. However the man page also shows: If
