I use an open source DVR called MythTV. I've just swapped from using

I've run into one thing I used to do with the old system that I cannot
find out how to achieve with the new.

MythTV doesn't currently entirely handle starting without a TV
connected. With nvidia graphics I could specify, within the X config,
the "ConnectMonitor" and "CustomEDID" options to fool MythTV into
thinking there was a TV. With intel graphics I can load EDID, but so far
I haven't discovered an equivalent of the "ConnectedMonitor" option.

Sorry for the delay, I seem to have missed this.

Please try a kernel command-line parameter to force enable the
connector.

video=TV-1:e

Assuming the connector name is "TV-1"; replace with whatever you have.


Thanks for the reply. I gave that a try, in my case "video=HDMI1:e", but saw no difference. That's KMS, right? Is there anything I might have failed to install or enable that KMS relies on? Are there any logs I should monitor?
