A workaround is blacklisting the amdgpu module and use radeon instead, but this should not be needed on 270X. Please attach the output of dmesg and xrandr and the Xorg log file corresponding to the problem. What does "wrong position" mean exactly? What would be correct?

What would be correct? Hi Michel, Thanks for your reply. :) I'll attach the logs and a screenshot later today. When starting starting Xorg instead of Wayland on amdgpu (blacklisting radeon), the screen position is moving 5 pixels to the right, instead of being aligned in the center. When using the radeon module (and blacklisting amdgpu), the screen position is aligned correctly. It therefore seems the width/position of the screen is calculated incorrectly, but only on X.

Sorry for the delay. I've added the requested logs and provided a photo of what is happening on my screen atm. when using AMDGPU. Thanks and please let me know if more info is needed. :) setting amdgpu.audio=0 should work around it. Audio support for SI in amdgpu will land upstream for 4.13 @Alex Deucher: Thanks! :) This indeed fixes the incorrect monitor/screen position. $ dmesg|grep -i amd [ 0.000000] Command line: initrd=\intel-ucode.img initrd=\initramfs-linux.img cryptdevice=UUID=ec38-43d6-bd67-d8ab219518dc:root:allow-discards root=/dev/mapper/root amdgpu.audio=0 intel_iommu=pt nowatchdog rw [ 0.000000] RAMDISK: [mem 0x7eeb6000-0x7fffefff] [ 0.000000] Kernel command line: initrd=\intel-ucode.img initrd=\initramfs-linux.img cryptdevice=UUID=8d188525-ec38-43d6-bd67-d8ab219518dc:root:allow-discards root=/dev/mapper/root amdgpu.audio=0 intel_iommu=pt nowatchdog rw [ 0.805446] [drm] amdgpu kernel modesetting enabled.
