[Nouveau] [Bug 73267] Nouveau: corrupted laptop screen's EDID info

--- Comment #1 from Ilia Mirkin <imirkin at alum.mit.edu> ---
It appears that the correct values for the first 8 bytes are

00 ff ff ff ff ff ff 00

whereas you have them as

00 00 00 00 00 07 4f 00

(based on your earlier boots, and the last comment from bug 34554). Try to
stick the "correct" EDID into a file, and force its use via module options.
Take a look at

https://wiki.archlinux.org/index.php/Kernel_Mode_Setting#Forcing_modes_and_EDID

specifically, you need something like:

drm_kms_helper.edid_firmware=LVDS-1:edid/your_edid.bin
