If that layer that [is|must surely be] providing X configuration
out of Quartz's runtime state in lieu of an /etc/X11/xorg.conf
could produce a ServerLayout and Screen sections that actually
reflect a multi-screened Mac's setup at that moment rather than
creating a single screen that's a union of all the Mac screens...
maybe all xinerama stuff would suddenly start working? :-D
XINERAMA and PseudoramiX are, AFAICT, the same thing. It's the X11
extension that makes two monitors look like one screen.
No, I think xinerama is the whole bunch of multi-screen
functionality isn't it? And having it be one logical screen is just
one setting (and an almost useless one IMHO). Maybe that's not what
xinerama is; I thought it was, but I'm not claiming special
expertise and I may have been labouring under a terminology
misapprehension.
Nope, the only thing Xinerama does is "one logical screen". Multiple
independent screens (with no window dragging across screens) is X11's
default behavior without Xinerama. ServerLayout et al are part of the
XFree86 driver infrastructure, which Xquartz doesn't use at all.
screen #0:
print screen: no
dimensions: 3360x1050 pixels (1138x356 millimeters)
resolution: 75x75 dots per inch
depths (7): 24, 1, 4, 8, 15, 16, 32
root window id: 0x3f
depth of root window: 24 planes
number of colormaps: minimum 1, maximum 1
Maybe because xinerama isn't made relevant by the fact that it's
only being told about one (very wide) physical screen?
Same with Xquartz -xinerama which says it's supposed to disable
xinerama. However one difference is that xdpyinfo still lists
XINERAMA whereas with -extension XINERAMA it doesn't; but the single
screen size remains the same.
I'm guessing there's a bug where `-xinerama` and `-extension XINERAMA`
don't actually turn Xinerama off. Try running `xdpyinfo -ext
XINERAMA`. If you see something like the following, then Xinerama is
still enabled and still running one logical screen.
% xdpyinfo -ext XINERAMA
