hi,
i have a problem with my VGA TV: with KMS it automatically sets bad video resolution and shows black screen on TTY. To solve and boot openbox i have to set autologin, autostartx and add "xrandr -s 1024x768" on autostart of openbox.
To show TTY i have made an EDID firmware with get-edid:
$ sudo get.edid > /usr/lib/firmware/edid/1024x768.bin
$ sudo parse-edid < /usr/lib/firmware/edid/1024x768.bin
and add it to GRUB:
drm_kms_helper.edid_firmware=edid/1024x768.bin
It works, the only problem is that with edid i have only one resolution (1024x768) and one refresh rate (60Hz), why?
xrandr with EDID:
