I got the following error: [ 135.566642] EDID block 0 is all zeroes [ 135.566831] amdgpu 0000:0f:00.0: [drm] User-defined mode not supported: "2560x1440": 144 592000 2560 2568 2600 2666 1440 1465 1470 1543 0x60 0x9 [ 135.566836] amdgpu 0000:0f:00.0: [drm] User-defined mode not supported: "2560x1440": 144 807923 2560 2784 3072 3584 1440 1441 1444 1565 0x20 0x6 After this, the only available mode is 640x480. This happens with both my displays, a monitor and a TV. I have a Radeon RX 6800 XT that previously wo= rked fine in this regard. I usually override the EDID with drm.edid_firmware, but removing this has not helped. I tried bisecting the issue, but perhaps it doesn't happen every single tim= e, as it lead my down a dead end. I also tried reverting some potential culpri= ts, to no avail. I can see that there were some very large EDID-related changes= by Jani Nikula for 6.2. I wasn't able to revert these, so I will CC them here. I am happy to provide further information. --=20 You may reply to this email to add a comment.
