#60661 — Bug#894731: linux-image-4.15.0-2-amd64: Setting drm.edid_firmware or drm_kms_firmware.edid_firmware has no effect

Hi,

I'm also affected by this issue. I have a horrible samsung TV which I
use as monitor in my desktop that doesn't send correct EDIDs (it simply
doesn't send any EDID). I was working OK with kernel 4.13. Today I have
upgraded to 4.15.0-2 and TV is showing mode setting not supported, so
the option is not recognized (I've tested with
drm_kms_helper.edid_firmware and drm.edid_firmware with no luck). I'm
configured grub to use the old kernel for the moment.

Thanks

Thanks Henrik, it's working for me too after adding "video=HDMI-A-1:e"
in my case.
