Xinerama

Jon,

Looking further into Xinerama, I think I brushed it off too early.  It
is *very* widely supported[1], and while XRandR is supposed to replace
it, actual implementation and usage may be some time off.

I also think that there may be some potential flaws in windowed
multiplemonitor mode that Xinerama support would fix.  While the current
behaviour makes sense in multiwindow mode, I'm not sure that it does in
windowed mode.  Since X window managers have no sense of what is really
happening in that case, placing a dialog in the centre of the X display
could easily land on the seam between two monitors.  (I know, I tried
it.)  With Xinerama support, however, they would have the necessary
information to DTRT.

I think that the implementation may be simpler than we thought.  To see
the situation as it stands:

1) Build and install xineramaproto;
2) Remove the --disable-xinerama flag from xorg-server and rebuild;
3) Build and install libXinerama;
4) Remove --without-xinerama from xdpyinfo and rebuild.

For this example, on my single-head system I launched XWin with:

X +xinerama -nodecoration -screen 0 640x480 -screen 1 640x480+640+0

This gives :0.0 and :0.1 side-by-side.  If you have a multihead system,
you could just as easily run:

where is /usr/X11R6/lib/libGLw.a on cygwin?

Hi,

  I am getting this undefined reference to `_glwM2DrawingAreaWidgetClass' error:

$ g++ componentTest.o libInventorWidget.a -lInventorXt -lInventor -lstdc++ -L/usr/X11R6/lib
-L/usr/local/lib -limage -ljpeg -liconv -lFL -lfreetype -lGL -lGLU -lXm -lXt -lXext -lXi -lX11 -lm   -o componentTest
libInventorWidget.a(MyTextureEd.o):MyTextureEd.c++:(.text+0x6b3a): undefined reference to `_glwM2DrawingAreaWidgetClass'

and it is due to this line in MyTextureEd.c++:

    Widget glx = XtCreateWidget("paletteGLX", glwMDrawingAreaWidgetClass, parent, args, n);

glwMDrawingAreaWidgetClass is defined in:
/usr/X11R6/include/GL/GLwDrawA.h:#  define glwMDrawingAreaWidgetClass   glwM2DrawingAreaWidgetClass

I know on linux "glwM2DrawingAreaWidgetClass" is defined in /usr/X11R6/lib/libGLw.a.
Does any one know where /usr/X11R6/lib/libGLw.a is on cygwin-1.7?

Thank you,

Linh

You can confirm package versions by running "cygcheck -r -s -v" and
attaching it to your email as suggested in:

No Cygwin-X shortcut on fresh install

Hi!

I have just installed Cygwin. I selected "gvim", "xorg-server" and
"rxvt-unicode-X" for packages.

After finishing the installation, I could not start X server from
"starx" etc. I could, though start X.exe.

Documentation says I should have "Cygwin-X" shortcut on the desktop. I
have reinstalled everything but I there is not shortcut.

Am I missing something? Something that needs to be installed?

Still problems starting X

On X11R6.99, I start X with a link on desktop, 'XWin Server', whose
target is:

    C:\cygwin\bin\run.exe bash -l start_XWin.sh

and in /usr/local/bin, start_XWin.sh is

----------------------------
#! /bin/bash
export DISPLAY=127.0.0.1:0.0

export PATH=/usr/bin:"$PATH"

# Cleanup from last run.
rm -rf /tmp/.X11-unix

# We have added +bs, i.e. BackingStore
XWin -multiwindow -clipboard -silent-dup-error +bs &

# Return from sh.
exit
----------------------------

It is just /usr/bin/startxwin.sh stripped from superfluous comments,
from the start of xterm and with +bs for XWin.

It starts only the X server.

With X11R6.99 this works just fine, but with the new X11R7.4 (also -3)
there are two annoying dos windows (which appear for less than an

I don't think 3 is related to you crash.
I see multiple lines with

GetWindowProp - pWin or name was NULL

for any window that I create, not only GL
related. 

6 lines for glxgears and gnuplot
8 lines for rxvt

Re: Problem with OpenGL on new X serverl

After a grep in the sources, I see the error is from file
cygwin-net_wm_icon-support.patch. But i'm not sure that the error is
in relation with the crash. I will try to run the program under a
debugger.

multiwindow support for _NET_WM_STATE_SKIP_TASKBAR

Jon,

Following up on our discussion about multiwindow not honouring
_NET_WM_STATE_SKIP_TASKBAR.  The attached patch was what I had in mind
but it has no effect.  I'm posting this now to at least start the
discussion.

You may wish to refer to the FD.o EWMH specs:

http://standards.freedesktop.org/wm-spec/wm-spec-1.4.html

Yaakov
Cygwin/X

Process _NET_WM_STATE_SKIP_TASKBAR in multiwindow.

FIXME: This does NOT work yet.
