I was able to work around this problem by using the xorg.conf option
"CustomEDID". The goal is to essentially tell the system to pretend that
your particular model of monitor/TV is always connected to the port in
question.
First, run this to determine the name of the video port in question:
xrandr -d :0 --auto
Then, generate an edid file with the 'get-edid' utility. You can pipe
the output into the edid-decode utility to see it, and eventually output
it to a file (I used /root/edid.bin).
Then add something like this to your /etc/X11/xorg.conf, inside the "Device"
section:
Option "UseHotplugEvents" "False"
Option "ConnectedMonitor" "HDMI-0"
Option "UseDisplayDevice" "HDMI-0"
Option "CustomEDID" "HDMI-0:/root/edid.bin"
Where HDMI-0 is the video port name you got from xrandr.
If you don't already have an xorg.conf file, you'll need to make one
somehow. The "nvidia-xconfig" executable worked for me, but I'm sure it
will vary depending on the video card and driver in question.
WARNING: I've read that using the CustomEDID option with an incorrect
edid file (such as one for the wrong monitor or a different port) can
cause hardware damage!
