RE: Rootless mode only works on one monitor

["Marcus Lindblom" <d98macke at dtek dot chalmers dot se>]

I sort of did that, didn't I? ;)

Note that I am running both monitors from the same graphics adapter, and
use driver software to link them together as one big screen. I haven't
tested using the WinXP-multimon feature, or using two separate adapters.
(I have a voodoo2 which I used with a GF1 before I got the GF4).

I think XWin tries to open one maximized window (albeit transparent or
non-existant, whatever, anyway it uses that as a measure on how big the
screen is), and only create subwindows within that border. As you
probably know, maximizing a window with Windows-multimon only put's it
on one screen, so XWin only get's one screen. As I said, I use nView
(nVidia driver thingy) to get one big monitor, so windows doesn't know
that it's two of them, thus no problem in running xwin on two monitors,
as it is only one.

This is a bit silly if you're running rootless though, but I do believe
that is why it works for me. (It fits the problems and my solutions to
it below, i.e. I had to start xwin-test67.exe non-rootless and tell
nview to allow it to maximize to both screens, then I could get rootless
windows on both monitors.)
