I have 2 displays on 1 card. i can get them both active w/window managers, or get one active w/window manager with the other detected
I want to explore initializing displays manualy or using a seperate display as a video output device. X but no Wm, enough to have it refferenceable via DISPLAY=:N.n
Im sure there must be a way to CLI a display active and to activeate a seccond Xserver without your first shutting off. (when i "X :1" from :0 , :0 turns off and :1 activates)
thank you for reading, and any assistance 
xrandr output when 1 is active(w/wm) and other is not
| Code: | ~ $ xrandr

For example for nvidia I think the feature was called twinview and works only with the nivdia-binary blob.
So you may tell us which gpu you utilize and which gpu implementation. So the next guy reading your topic can answer your question.. |

GPU = Nvidia [01:00.0 VGA compatible controller: NVIDIA Corporation G92 [GeForce 8800 GT] (rev a2)]
Driver = Nvidia proprietary 340.76
also somthing i can do which suggests my plan would work is, when both are active
| Code: | | DISPLAY=:0.1 xrandr --output DVI-I-3 --off |
disables the seccond display
| Code: | | DISPLAY=:0.1 xrandr --output DVI-I-3 --auto |
causes the seccond display to return
I have already gotten twinview and xinerama working and though nice its not what im looking for. i want x controll limited to one display and to controll what happens on the second display via cli
limited x controll is easily achieved when using absolute layout mode and the virtual displays are not positioned side by side, but still runs wm on display :0.1
