PVR Booting with LCD off
on Feb.10, 2009, under Linux
When things are working well, my PVR box is supposed to wake-on-LAN about the time I get home, and be ready for use. Since the LCD, the box wouldn’t be driving the display after boot. I would have to kill and restart X with the LCD powered on. Apparently this is due the NVIDIA driver needing to read the EDID from the LCD to figure out what resolution to use. I tried a variety of ways forcing it to work without validating the resolution, but I ended up downloading the EDID to a file (using the nvidia-settings gui) and having the driver run against that. Not that inelegant, I think.

I’m pretty sure that’s the appropriate method to use here.
