Hi,
I use Cygwin/X to display a CAD application on my Windows cient. For
some reason new windows always open on the secondary display and I
always need to manually drag them to my primary display. That's sooo
annoying (since UNIX applications tend to open new windows on every action).
To avoid this, I want to disable the second monitor (and *only* use the
primary). But whatever I do, XWin seems to ignore whatever I supply. For
example, I start
/usr/bin/startxwin.exe -- -nomultiplemonitors
/usr/bin/startxwin.exe -- -screen 0 @1 -nomultiplemonitors
/usr/bin/startxwin.exe -- -screen 0 @1
/usr/bin/startxwin.exe -- -mwextwm -screen 0 @1 -nomultiplemonitors
and so on.
Nothing works - everything as before. When I select "Hide Root Window"
from the tray icon I see that the root window indeed covers both monitors.
Any suggestions?
Thanks,
Luke

I'm assuming that your secondary display is to the left of your primary
display.
I think that it's a bug that these windows are appearing at the
top-left, rather than on the primary display, in that we don't
distinguish well enough between "the application asked us to place the
window at 0x0" and "the application didn't specify where to put the window"
It would help if you could give the name of this application, and can
you install 'xprop', and show the output you get from running that, then
clicking on one of the window which gets placed incorrectly.

This is not how it behaves for me. Using -nomultiplemontiors, or an
explicit -screen setting shows an appropriately sized root window when
turning off "Hide Root Window". (Although this is not terribly useful as
you can move the Windows windows out of this area, which causes their
contents to not be drawn)
Can you check if the screen dimensions reported by xdpyinfo match those
you are requesting, and attach your /var/log/xwin/XWin.0.log?
Separately, it's possible that we should do something better with the
combination of -nomultiplemontors and -multiwindow, but it's not quite
clear to me what. (See discussion [1])

Yes.
Secondary: builtin laptop display (on left)
Primary: main monitor (on right)
If I do "Identify", the laptop display is identified as "1" and the main
monitor as "2".

Sure.

You are right. Further research shows me that my arguments never showed
up in XWin.0.log. Maybe I there's a different bug here?
I call XWin like this:
C:\cygwin\bin\run.exe /usr/bin/bash.exe -l -c /usr/bin/startxwin.exe --
-nomultimonitors
And this appears in XWin.0.log:
XWin was started with the following command line:
X :0 -multiwindow
However, if I directly start the XServer,
XWin.exe -screen 0 @1 -multiwindow -nomultimonitors
it works:
XWin was started with the following command line:
XWin -screen 0 @1 -multiwindow -nomultimonitors
Why does startxwin.exe does not pass the parameters to the XServer.
However, unfortunately this does not change anything: You are right that
when I uncheck "Hide Root window", the black root window *only* covers
the primary monitor. That's good.
But windows are *still* opened at the second monitor!
What's even worse (and pretty astonishing to me): All X windows are
*only* displayed correctly on the *secondary* display with the command
line above. On the primary display, the window frames are shown but the
windows are not drawn (they are transparent) and they do not accept
mouse/keyboard input.
So it's completely the oppisite as it is intended ...

Hmm, I have here:

I think that's fine.
XWin.0.log with the command line from above is attached.

I would reaaaally appreciate that.
Unfortunately I am not really an X expert.
What bothers me a little bit is that windows are displayed on a screen
which should not even exist. (besides the problem reported above that
the windows are not even drawn on the intended screen).
Thanks

Hmmm...
There are 2 possible flags here: "program specified location" and "user
specified location" (e.g. by using -geometry on the command line), and
at the moment we honour them both.
Now, it might be that the client expects to see some EWMH capabilities
advertised by the multiwindow mode WM, the absence of which causes it to
set this, or it only sets this after the window is placed, but if it
always creates the window with that property, it's not clear how to fix
this.
(Just ignoring "program specified location" is tempting, but there are
legitimate uses, for example a toolbar window which should be placed at
the side)
So, do you have an example of this working as you would like on a unix
system, and what is the window manager is that case?
I've built a snapshot [1], which adds a heuristic which ignores a
'program specified location' hint if the location is the origin, which
you might like to try and see if that fixes your problem, but I'm not
sure if that is the correct solution.
(I also found a bug with how this hint is handled in 64-bit builds, but
I don't think that affects you)

You need to quote the whole command after bash's -c flag, otherwise they
are interpreted as additional flags to bash.
See http://x.cygwin.com/docs/faq/cygwin-x-faq.html#q-command-line-args
for an example.

Yes, it seems there is also something wrong with the translation between
Windows (which has 0,0 at the top-left of the primary monitor) and X
(which has 0,0 at the top-left of the virtual screen) coordinate spaces
here.
But even if that was fixed, there is still the problem of how X windows
are supposed to behave when moved off the virtual screen (not allowed to
move? empty?)
Because of that, assuming that I can fix your problem with correct
window placement, I am inclined to just disable the combination of
-multiwindow and -screen.

Hi Jon,
First of all, thank you so much for your effort!
I am struggling for so long with the issue and I am so happy to see your

Thank you! I think I understand it (I am no X expert).

Sounds legitimate.
Aside: Maybe it's possible to make this configurable via config or
environment variable? (but I guess the X server does not see environment
variables etc.)

I am not sure if I get the question.
What I could do is to login via VNC and see how the windows are placed
are if they are placed the correct way?
Is this what you mean?
Unfortunately I have no chance to install Cadence locally and run it
from a local, dual monitor setup from Linux because Cadence is a
proprietary, expensive tool.

Thanks so much for that!
I have just the issue that the exe does not seem to work for me. Is
there anything special I need to consider?
I tried copying both, 63 and 32 bit versions to c:\cygwin\bin:
32 bit version gives:
c:\cygwin\bin>XWin.new.32
XWin.new.32:./.libs/lt-XWin.c:233: FATAL: couldn't find XWin.new.32.
And 64 bit gives: "The application was unable to start correctly
(0xc000007b). Click OK to close the application".
What bothers me is that my original XWin.exe has 2363943 Bytes (and the
X icon) whereas your new versions are just 26624 and 27150 Byes (and no
icon).
c:\cygwin\bin>uname -a

Thanks but I think I have tried that already.
It may be hard to believe but:

I mean something different here: Even when I just start the local
xterm.exe the problem appears. And it's reproduceable:
XWin was started with the following command line:
XWin -screen 0 @1 -multiwindow -nomultimonitors
When, if I start xterm.exe, it is not rendered on the *primary* monitor
at all (only the window frame is and whichever content was previously
displayed in the window).
Only if I drag the xterm window to the secondary display (which is not
even supposed to exist now), the content is updated/rendered.

I am not sure if I understand the question but in my humble
understanding this can't just happen: it would behave the same as if you
moved the window out of the monitor. The part moved out is just not
displayed.

I understand. I have no idea about the implications and the
implementation details; in my humble understanding it would just work as
described above ;-) But that's probably too simplified ...
Thanks,
Luke

I understand that.
I am just looking for some evidence that it isn't a bug in the
application, i.e. that it works correctly for *anyone* :D
Knowing a window manager which places these windows correctly would also
give me some source code to look at to work out what I need to change.

Sorry, my snapshot building script went wrong and the snapshot was
broken. Try this one instead.

Hmm, what I just did is that I started a VNC session and used VNC.
Everything seems to work as expected, new windows are /not/ placed at (0,0).
Window manager is Gnome.
However, as mentioned, this is clearly not a local multi-monitor X
session :(

Can't believe it, great! Works exactly as it should (just with the
standard configuration, "X :0 -multiwindow")!!
Now I just hope that this 'patch' somehow finds its way into the trunk ;-)

This fix is included is 1.15.1-3.
On reflection, I think a better approach would be to look at
_NET_WM_WINDOW_TYPE and if it's _NET_WM_TYPE_NORMAL or absent, ignore
PPosition and place the window as we like, but that is not quite as
straightforward to implement.
