Created attachment 142991 [details] Xorg.0.log with modesetting +++ This bug was initially created as a clone of Bug #103953 +++ I have 3 Dell WQHD Screens (2560x1440) screens, connected to a Radeon RX580 (XFX, RX-580 GTS Black Edition, 1425 MHz 8GB). My kernel is: Linux edison 4.19.13-300.fc29.x86_64 #1 SMP Sat Dec 29 22:54:28 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux With the default boot settings, which enable amdgpu.dc, I am unable to get the native resolution on one of the three monitors. If I disable amdgpu.dc on the kernel command line, I am able to get the native resolution on all three monitors. I have attached the Xorg.0.conf.old from the startup with amdgpu.dc at the default setting, and Xorg.0.conf from the startup with amdgpu.dc=0. I have also attached the initial part of the dmesg log from both boots: dmesg-amdgpudcdefault.log : default amdgpu.dc setting (enabled) dmesg-amdgpudc0.log : amdgpu.dc=0 The only relevant difference I see between the two is that with modesetting, I see the following errors: edison kernel: amdgpu: [powerplay] Failed to retrieve minimum clocks. edison kernel: amdgpu: [powerplay] Error in phm_get_clock_info whereas without modesetting I do not see those errors.
