Any idea whats up here?
The two files can confict if both are present; IOW, one can override the other if you forget. Building them from scratch is a beast as well. https://www.linuxquestions.org/questions/linux-hardware-18/twin-monitor-setu... contains a two screen, one device configuration I made just this AM. Note that there were no modelines or BusIDs required. Are you sure you understand the X meaning of "Screen"? It's been a very long time since I've seen a valid config file with Screen 0, Screen 1 and Screen 2. Are these 3 screens supposed to comprise one X desktop? Modelines in config files are anachronisms. CVT and GTF are no more competent than the X servers in generating the required modelines, as long as EDID is valid, or HorizSync and VertRefresh are provided in xorg.con*. Omitting modelines simplifies composing a valid configuration, and can migrate automatically if a display gets changed. I have a GT 630 I could put into a suitable Intel Graphics box if I understood what result you were trying for. When I need three displays I use three Intel IGP connectors, usually DP, HDMI & DVI, with VGA available as an alternate to any of the others. To configure I use a relatively simple xrandr command in a startup script, e.g.: xrandr --output DP-1 --mode 2560x1440 --primary --output HDMI-1 --mode 2560x1080 --above DP-1 --output HDMI-2 --mode 1920x1200 --above HDMI-1 # HDMI-2 is actually DVI. -- Evolution as taught in public schools, like religion, is based on faith, not on science.
