[Intel-gfx] Does the intel driver support faking a connected monitor?
I use an open source DVR called MythTV. I've just swapped from using nvidia graphics to intel graphics. Generally it's working great, but 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. ___ Intel-gfx mailing list Intel-gfx@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/intel-gfx
