Comment # 14
on bug 105046
from Michael Zapf
Anything new? The problem is still there, although now it falls back to a
higher resolution (1920x1080), still causing a mess on my desktop.
I would like to emphasize that this issue does not appear with amdgpu.dc=0. I
tested it several times to make sure.
I tried it with an own EDID file; picked it from the xrandr, then saved it to a
file /lib/firmware/edid/mizapfmon.bin. Then I added a kernel parameter
"drm.edid_firmware=edid/mizapfmon.bin". (drm_kms_helper is deprecated)
During boot:
Aug 12 01:07:08 capella kernel: platform HDMI-A-2: Direct firmware load for
edid/mizapfmon.bin failed with error -2
Aug 12 01:07:08 capella kernel: [drm:drm_load_edid_firmware [drm]] *ERROR*
Requesting EDID firmware "edid/mizapfmon.bin" failed (err=-2)
I don't know whether something is missing, maybe I have to add the firmware to
the initrd. But it is not required at boot time; the screen is OK at that time.
When I turn the monitor off and on again, I'm getting the following lines in
/var/log/messages, and the screen resolution is again reset to 1920x1080.
