Black screen on Mate on Odroid

Support & Help Requests

Hi,

I wish someone can help me here or in another board :slight_smile: because it's about Ubuntu Mate for Odroid.
My old Samsung SyncMaster 205bw was black (no text, no interface) with this fresh install of Ubuntu : ubuntu-20.04-5.4-mate-odroid-xu4-20210926.img

So I change config.ini with native resolution :

setenv videoconfig "drm_kms_helper.edid_firmware=edid/1680x1050.bin" // bad

and fail, so I try

setenv videoconfig "drm_kms_helper.edid_firmware=edid/1400x1050.bin" // better!

and it's ok but stretched (circles are ellipses).

I found this about my screen : https://elixir.bootlin.com/linux/latest/source/drivers/gpu/drm/drm_edid.c#L160 but don't know how to use this firmware :frowning:

note : this screen is in DVI with HDMI and it's OK on RPI4 (raspbian).
