Hi all,

I'm new to X11 programming. I am developing an OpenGL based software that run
in fullscreen on a twinview configuration (display card NVIDIA 5900XT), ie. in two
side-by-side 1024x768 screens as a single 2048x768 screen. I can create a
window with size 2048x768, but whenever I switch to fullscreen mode in my
program, all the content in the window is squeezed in 1024x768 resolution, even
though I resize the window to size 2048x768. I think it can be done as I have
KDE screensaver running fullscreen at 2048x768 resolution automatically. I
check with the Xlib programming manuals and can't find any reference on it. If
you have experience on doing it, please point me to the trick.

Thanks in advance.

I seem to recall from the xinerama howto that what you are observing is a
function of the window manager. Some window managers function that way,
others the way you want. I think if you check the howto you'll find some
guidance in that direction. I always wanted thw WM to 'maximize' to a
single monitor when I was running dual monitors, but that was primarily
because I was doing software support - I see your point.

Hi,

I am not using Xinerma to have dualhead configuration. I use the hardware
accelerated driver from NVIDIA. I try my program in both KDE 3.2 and GNOME 2.6
and I can only get fullscreen in one monitor only.
