Bug ID: 195737 Summary: AMDGPU: incorrect monitor position on Xorg Product: Drivers Version: 2.5 Kernel Version: 4.10.13 Hardware: All OS: Linux Tree: Mainline Status: NEW Severity: high Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@kernel-bugs.osdl.org Reporter: francois5537@gmail.com Regression: No
Starting KDE in Xorg on Linux 4.10.13 results in a wrong position being used by the monitor (LG 29UM58). When using Wayland instead the position is correctly calculated.

--- Comment #1 from beta990 (francois5537@gmail.com) --- A workaround is blacklisting the amdgpu module and use radeon instead, but this should not be needed on 270X.

--- Comment #2 from Michel Dänzer (michel@daenzer.net) --- 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?

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.

--- Comment #7 from beta990 (francois5537@gmail.com) --- 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. :)

--- Comment #8 from Alex Deucher (alexdeucher@gmail.com) --- setting amdgpu.audio=0 should work around it. Audio support for SI in amdgpu will land upstream for 4.13
