from Michel Dänzer
From the Xorg log file: [ 212.439] (II) AMDGPU(0): Allocate new frame buffer 1440x900 [ 212.439] (II) AMDGPU(0): => pitch 6144 bytes [ 212.639] (II) AMDGPU(0): Allocate new frame buffer 3360x1080 [ 212.639] (II) AMDGPU(0): => pitch 14336 bytes This does look like there are hotplug events, and the HDMI output is considered disconnected for a moment. (In reply to Alex Deucher from comment #5) > Some monitors poll inputs which sometimes causes the hpd pin to fire which > looks like a hotplug event to the driver. Any idea why this seems to only cause trouble with DC though? (I was seeing similar symptoms with DC and an HDMI connection with Kaveri, I reported it to the DC developers internally a while ago; it's one reason why I'm currently not using DC on this machine)
