It turns out the boot params "video=HDMI-A-1:e video=HDMI-A-2:e
video=HDMI-A-3:e" are what actually turned the tv "on". They seem to
default to "d". In any case I now have only that in my grub file except for
the "video=1024x768" and I'm not really sure what that actually does.
My /etc/modprobe.d/20-drm_kms_helper.conf contains:
options drm_kms_helper edid_firmware=HDMI-A-1:edid/lg42lb9df_hdmi1.edid
How can I add the other connector info to that file BTW?
It now looks like it is finding the edid file.
# cat /sys/module/drm_kms_helper/parameters/edid_firmware
HDMI-A-1:edid/lg42lb9df_hdmi1.edid
What I End up with is a 1024x768 on both the DVI and HDMI port outputs and
then every 5-10 seconds the below gets spewed to the log file and the
system is unresponsive while this occures. I don't understand why this
messes up the DVI port. With no 20-drm_kms_helper.conf file the DVI port
get 1600x1200

If so what would be the syntax?

Thanks
