[mythtv-users] Can't start mythfrontend with TV off since moving to Intel graphics

[Paul Gardiner]

I've recently moved from nvidia to Intel graphics for my frontend. With 
nvidia, I could specify CustomEDID and ConnectedMonitor options in my 
xorg.conf so that mythfrontend would start up before the TV was turned 
on, but Intel graphics doesn't support the ConnectedMonitor option and I 
so far can't find an alternative.

When mythfrontend starts it reports failure to find a screen and 
attempts to set a mode with 0fps, although xrandr correctly reports the 
modes specified via CustomEDID.

I've tried various alterations to no avail.

* Specifying custom edid and an enabled output via KMS, but that seemed 
to have no effect.

* Setting the primary output with xrandr before starting mythfrontend

* Specifying monitor definitions in the x config with the Ignore option 
set to True for all outputs other than HDMI1.

Nothing has worked, although the system has fooled me into thinking it 
is working several times.

Hope someone has some more suggestions. Here are various logs:
