Not sure why I have two instances of lightdm running
dad at NewMyth:~$ ps -e | grep dm
825 ? 00:00:00 lightdm
1096 ? 00:00:00 lightdm
My 750ti has three outputs, VGA-0, HDMI-0, DVI-D-0.
With just the two monitors hooked up my xorg.conf has this line in the
Screen section
Option "metamodes" "VGA-0: nvidia-auto-select +0+0, HDMI-0:
1920x1080 +1280+0"
I assume I could add the DVI monitor to this definition. What I don't know
is how I can get Myth to show up on both the HDMI and DVI monitors but not
on the VGA monitor.
Googling is good at finding examples with two monitors but not so much on
three.
The projector is a Panasonic PT-AX100U and it 720p native although it will
take other inputs.
