Re: nomultiplemonitors does not work in windowed mode

Hi,

According to XWin docs:
"-[no]multimonitors or -[no]multiplemonitors
Create a screen 0 that covers all monitors [the primary monitor] on a system with multiple monitors. This option is currently enabled by default in -multiwindow mode."

And this is exactly what happens. When I start a program, it shows up on both monitors (half here, half there). This is not supposed to happen (see next point).

I have 2 monitors. Imagine you turn off one of them and you want to use the other one only. Currently, Cygwin-X will span over all monitors - unless you use the multiplemonitors option. I think the goal for this option is very clear from the docs: use only 1 monitor for the root window, no matter what. So I would expect this behavior: you should not be able to move off windows from the primary monitor, at all. The point is, you want to limit the root window to one monitor only.

I see the -multiwindow and -nomultiplemonitors options completely independent from each other. They should not have any relationship at all. The first just tells how you want to map windows within the root window, while the other simply specifies how many monitors you want to use for the root window.

I thought it is very clear from the docs, however your questions make me uncertain. Isn't is supposed to work like that?

Thanks,
Endre
