Make sure that VGA is your primary display.
Should work the same way like connecting to a TV, the only difference is the peak-to-peak levels that the arcade monitor requires which is handled by the jpac's video-amp, that has nothing to do with edid or video configuration...

I did it like this:
Code:
# set VGA output:
xrandr --newmode "2560x240" 48.23 2560 2632 2856 3080 240 242 245 261 -hsync -vsync
xrandr --output HDMI-1 --off
xrandr --addmode VGA-1 "2560x240"
xrandr --output VGA-1 --primary
xrandr --output VGA-1 --mode "2560x240"
# set gamma to 0.8, looks better on the tube:
xrandr --output VGA-1 --gamma .8:.8:.8
# disable screensaver:
xset -dpms
xset s off
xset s noblank
