Anyone with a JPAC / Arcade monitor?

[TwinX]

Hi,

I installed Lubuntu and all goes well.

On LCD

Whenever i attach a arcade monitor or JPAC to the vga-0  xrandr says no disconnected. (lcd connected to DVI-0 that works)

Do i need to do something special for screens without edid information.?

Thanks

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
