Second display software control and access.
I have bought 2xLCD 3D glasses Video Eyewear EVG920D 640x480 which can be connected to pc via usb and VGA. Manual says that 3D mode supported in interlaced format. I think 3D works in fullscreen mode in 640x480i or 320x200i.
Question is how to setup via command line and from C++/C# second video output as Screen :1(or whatever),set video mode(only to this display) and pass some application output to it? |
Your question is not very clear. Are your display configured to run 3D? It's not automatic as far as I know. Are your glasses active or passive? You are looking for a way to display half of the vertical line every frame? Have you looked at doing this on the applications you want to display instead of X, because I don't think it is X job to handle that.

They have special mode switch 2D/3D.
Display = 3D Glasses. 3D glasses have own builtin LCD display with 640x480 resolution(aka Human Mounted Display). In general i wish to 1) setup 640x480 videocard output2 as screen 2 (not as part of virtual resolution!) 2) pass some application output to it. 3) interlaced mode? - i dunno but maybe i need to pass 2 images(one slightly shifted) line-over-line to output valid 3d frame format. |
I am not quite sure to understand what your are asking exactly (just "how can I get it to work" is not a question, I need much, much more details for that and readeaing the manual and spec, something that I will not do).
To display an application of the second screen, from the command line, write Code:
DISPLAY=:1 myApplication |
i managed to configure screen:0 and screen:1 with xrandr.
what i need for tests in command line is analogue to this pseudo-code var display=system.display{2} //tryed C# mono opentk but it fail to work correctly display.setGraphicsMode=GraphicsMode.640x480_fullscreen; //i really need this display.setGraphicsModeFrequency=Frequency.60hz var applicationstdout=system.exec('3dapp'); // SOLVED by DISPLAY=:1 applicationstdout.output=display; // SOLVED by DISPLAY=:1 well it's X job to display images generated in 3d :) 3D and frame format for device is my headache :) Thnx for help Elv13 |
