[Bug 1212954] New: amdgpu: Monitor displaying wrong resolution
https://bugzilla.suse.com/show_bug.cgi?id=1212954 Bug ID: 1212954 Summary: amdgpu: Monitor displaying wrong resolution Classification: openSUSE Product: openSUSE Distribution Version: Leap 15.5 Hardware: Other OS: openSUSE Leap 15.5 Status: NEW Severity: Normal Priority: P5 - None Component: X.Org Assignee: gfx-bugs@suse.de Reporter: holgi@suse.com QA Contact: gfx-bugs@suse.de Target Milestone: --- Found By: --- Blocker: --- Created attachment 867944 --> https://bugzilla.suse.com/attachment.cgi?id=867944&action=edit IMG_20230703_164538751_HDR.jpg Having a 4K monitor (SAMSUNG LU28R55) attached to the docking station of my ThinkPad via HDMI I can easily 1:1 mirror the screen output of the laptop and the monitor with openSUSE Leap 15.4. Doing the same with openSUSE Leap 15.5 will result in monitor displaying a resolution 1980x2160 instead of the set 1980x1080. Using a 4x different screen (Philips) is working fine.

Test with the one in OBS Kernel:stable:Backport repo. If the upstream kernel is confirmed to work, test with the one in OBS home:tiwai:kernel:6.3 and home:tiwai:kernel:6.2 (use "backport" repo for Leap -- "standard" is for TW), so that we can narrow down a regression fix range. -- You are receiving this mail because: You are on the CC list for the bug.
