BTW, does OpenGL still not work with dual monitors? I could never get OpenGL to work when I had an GeForce 2 and a Diamond Stealth 2000 both working together. Since I''m constantly working on my landscape engine with OpenGL it wasn''t worth it to keep turning multimonitor on and off, especially in Linux, so I just stopped using it. I''d love to get it back though, and have OpenGL work.

I think that depends on the driver. With the Matrox G450 here at work, I can get dual-head (not dual video card) support but can only get DRI support on one head, not both. So you can''t use Xinerama mode either and get DRI. From what I can see, this is all limitations of the Matrox driver (BETA).

I haven''t heard of any limitation of OpenGL in a second screen. I can run "glxgears" on the non-DRI screen as well, just slightly slower (software mode).

That what you mean?

The game (glTron) you see in the screenshot runs with openGL and works in both screens.

now this is cool... if I turn xinerama off, X behaves like if it were running in two machines, one machine in each monitor... and you can use both!!

Does this works for n monitors?

this is soooooooooooooooo cool.... *vibrates*

Yes.

You can build some pretty complex screen layouts with the relationship commands for screen in your XF86Config. I haven''t played with it too much, but I believe you can also run commands by the CLI and send them to the respective screens with the proper X notation.

I haven''t found a tool to switch running UI processes to another screen though, anyone know of one off the top of their heads?

you can make programs you run from a terminal come up on the screen of your choice by setting the display variable to that of the other monitor. for example on my second monitor normally DISPLAY=":0.1" but if you set that to 0.0 (or the right number for whatever screen you want to put it on) any X programs you run will start on the other screen. which is pretty useful when i''m testing my game where i use an xterm on my second display to compile everything, but then i can;t run it becasue that card doesn''t have opengl support, so using this i can make it come up on the main screen.

as for switching programs to different screens after they are running this is something i''ve wanted to do for a long time but haven''t found (or looked) for a way to do it.
