Hi,

I have two monitors each rendered by separate graphics card(Nvidia GT630). My desktop screen(suse linux) is on one of the monitors(say it MAIN). However, I can move my application windows to the second monitor. When I run the ‘monitors’ test program, it shows that I have only one monitor, and returns the resolution for it(MAIN monitor). when I create a window for sample application that I have, in fullscreen mode, the application window is seen only on MAIN and does not span on the second monitor.

Why does not the ‘monitors’ program return the number of monitors as 2 ?  
I assume my MAIN monitor is X11 screen 0 and other monitor is X11 screen 1.

Any idea what is happening here ?

Thanks,  
Sheeri

I have a game application where I want separate window(fullscreen) for each X11 screen.  
for example, in my case since I have two monitors with each representing separate X11 screens(0&1 in this case) I want to create two separate windows on these x11 screens.

Is there a way I can do this ? Currently, as mentioned in the previous comment the ‘monitors’ program returs only one monitor(main), and there is no way I can give x11 screen as an argument to GLFW create window API.
