Hello!
I tested groovy arcade with a Hantarex monitor and a simple breakout-cable (RGB/G/H/V) and its working.
Then i saved the xorg.conf and tried to use the modeline with lubuntu on the same hardware.
With a VGA2SCART-cable/TV-Set i get a picture. But non with the breakout-cable/Hantarex.
xrandr shows that the port where the breakout-cable is connected appears as disconnected and "xrandr --output DVI-1 --mode ..." doesn't work . With the VGA2SCART-cable/TV-Set it shows up as connected.
linux >xrandr --newmode "648x480x60.00-1525-1570" 13.129200 648 672 736 840 480 482 488 521 -HSync -VSync interlace
linux > xrandr --addmode DVI-1 "648x480x60.00-1525-1570"
linux >xrandr --output DVI-1 --mode "648x480x60.00-1525-1570"
linux > xrandr
240x240@58,795 48.7
DIN disconnected (normal left inverted right x axis y axis)
DVI-1 disconnected (normal left inverted right x axis y axis)
648x480x60.00-1525-1570 30.0
...
I don't belive that the old tube monitor sends EDID data. There must be some other kind of detection. How does Groovy Arcade do this?
Many thanks
