Thanks for the clarification. For those interested, gnome-shell is as broken as xfce is when it comes to handling monitors.

Window / Choose monitor
« on: September 02, 2014, 04:36:46 pm »
Hello. I have not posted here in years, but I'm glad to see that my account is still accessible! This time, my Google-fu won't do, so I have to make a question on my own.
Consider a set-up with two different monitors:
sf::VideoMode::getFullscreenModes() returns:
Notice that 3280 = 1920 + 1360 is the total width of the desktop (additional question: how to detect these pseudo-modes?). The following lines are video modes for the secondary monitor. Subsequently, when using 1920x1080, the primary monitor is switched off and the resolution of the secondary is changed. SFML does not support dual fullscreen but…
Q: Is there a way to force SFML to use the primary monitor?
Edit: it might be the fault of xrandr which does not actually set the correct monitor as primary, even with --primary ; it might be useful to have a way to select a monitor through SFML but I am not sure it would be worth it before multiple monitors are supported.
Edit 2: this is apparently due to a bug in XFCE. The additional question remains:
Q: Can we distinguish video modes spanned over several monitors?
Consider a set-up with two different monitors:
$ xrandr
...
// secondary
1360x768 60.02*+
1920x1080 60.00 59.94 50.00 29.97 25.00 23.97 60.05 60.00 50.04
...
// primary
1920x1080 60.00*+
