--- Comment #1 from Nicholas Kazlauskas (nicholas.kazlauskas@amd.com) --- The revert was only supposed to apply to 4.18 and below, there should be a series of patches that fixes this for 4.19.

Please post an updated dmesg log for your 4.19 kernel.

I'm hitting the same issue with one of my monitors (ASUS VG248QE, G-Sync modded). I tried extracting EDID from kernel 4.18 and forcing it with drm.edid_firmware as you can see in the log, but that doesn't seem to do anything. My GPU is AMD RX 580.

--- Comment #7 from Elliot Thomas (e.singularitycat@gmail.com) --- Same here, RX580 and an ASUS PG278Q monitor, also with G-Sync support. A different DisplayPort monitor (without G-Sync) worked perfectly.

I've noticed someone else with the same monitor having this issue over on the freedesktop bug tracker: https://bugs.freedesktop.org/show_bug.cgi?id=108806

Interestingly, in more recent kernels, the affected monitor appears to flash rapidly. I still see the EDID read fail in this case. I'll try and grab a dmesg of this at some point.

https://bugzilla.kernel.org/show_bug.cgi?id=201497

--- Comment #15 from Ivan Molodetskikh (yalterz@gmail.com) --- I managed to force the kernel to use the EDID extracted via get-edid on kernel 4.18 thanks to https://bugzilla.kernel.org/show_bug.cgi?id=199799#c4 . The trick was to add video=DP-4:e to the kernel parameters, so in my case the complete addition looks like:

drm.edid_firmware=DP-4:edid/ASUS_VG248QE.bin video=DP-4:e

ASUS_VG248QE.bin was extracted with get-edid on kernel 4.18 and placed in /usr/lib/firmware/edid/. With this in place, I can use my monitor fine on the latest kernel (5.5.5).

Without this, I have the exact same issue on 5.5.5.

I believe am hitting the same issue.

I have a DP monitor ACER XB270HAbprz and it is stuck in 640x480 on my RX 580.

This is on Linux 5.8.

On monitor replug this relevant line pops up: [drm:dc_link_detect_helper [amdgpu]] *ERROR* No EDID read.

This same monitor with the same cable works great on GTX 970 and GTX 1080 Ti under Nvidia 455.23.04.

--- Comment #18 from chriskoch@goldmail.de --- A short update: In the meantime I am adding the modeline for my monitor manualy. The automated solution is a 10-monitor.conf like in this thread: https://archived.forum.manjaro.org/t/stuck-at-low-display-resolution/115976 This works until Kernel 5.8. With Kernel >= 5.9 my monitor doesn't accept the modeline anymore. Since this problem has been reported 2 years ago and nothing happened, I am wondering if it will ever be fixed. Let me know how I can follow up/contribute to fix this.

--- Comment #19 from xavier B (xavierb@gmail.com) --- hi!

I had this issue for a longtime. And then, I recently got a new hdmi cable and never had the error since!

(or at least symptoms of it: the pc having trouble to enable the display after a warm reboot, and having to do a 'really' cold reboot by turning the pc off for a few minutes to get it back. I haven't been checking the logs extensively since it now works...)

--- Comment #21 from Sebastien Bernard (sbernard@nerim.net) --- The more I think about it, the more it seems to be related only to this monitor.

I think the 4.19 kernel closed a bug and is rejectiting the EDID reported by this screen.

If someone could validate this EDID is correct, it'll be of great help.

--- Comment #22 from Jay Tuckey (jay@tuckey.email) --- @Sebastien that could well be the case. The screen works fine under windows, but it could be that they are working around bad EDID data?

Is there any way I can validate if the EDID is bad?
