The fact that also XWin segfaults, means it isn't a problem only for ROOT developers... I'm not saying it's a problem only for them, I'm saying they know far more about the internals of ROOT than me. Please try to look at this from my perspective: For all I know, you may have 2 separate problems. For me geom/Shapes.C always segfaults ROOT unless I have XLIB_SKIP_ARGB_VISUALS set. This is suggestive that ROOT can't handle ARGB visuals. ROOT is the only OpenGL application that Cygwin/X has reported problems with at the moment.

Respect to the previous testing-XWin you have proposed, with XWin.20081203132739 also the keyboard works just fine!!! So, I doubt we are referring to the same failing XWin which one finds on the mirrors... I know you must be finding this frustrating, I know I am. But I am not lying to you when I say that I am using Xwin.exe from 1.5.3-4 and it doesn't fail for me when I run ROOT simple.C, irrespective of if I have +bs selected or not. I don't have some secret Cyginw/X goodness which I'm not putting into the X server which gets uploaded to the mirrors for some bizarre motive. :-) Ok. I've spent a bit more time to carefully build an image which should be identical to the 1.5.3-4 one except for the addition of debug symbols, so perhaps you could try ftp://cygwin.com/pub/cygwinx/XWin.20081204180806.exe.bz2 and see if that one fails for you. Failing that, can you post the XWin.exe.stackdump file which is generated when the 1.5.3-4 X server segfaults for you, and I'll see if I can extract some useful information from that. -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://x.cygwin.com/docs/ FAQ: http://x.cygwin.com/docs/faq/

Re: X, backingstore and opengl
This seem to be the same problem than me :
http://www.mail-archive.com/cygwin-xfree@cygwin.com/msg18009.html
2008/11/24 Angelo Graziosi [EMAIL PROTECTED]:
I want to flag the following problems I have met with X11R7.4 and the
application ROOT [1].
To reproduce them, you should not need to rebuild ROOT under X11R7.4
but it is sufficient to install pre-built binaries, even if they
result from a build under the previous X11R6.99: the 'effects' are the
same.
To install pre-built binaries, you have to do the following:
wget ftp://root.cern.ch/root/root_v5.21.04.win32gcc-gcc-3.4.tar.gz
tar -xzf root_v5.21.04.win32gcc-gcc-3.4.tar.gz -C /usr/local/
cd /usr/local
export ROOTSYS=/usr/local/root
export PATH=${PATH}:/usr/local/root/bin
export LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:/usr/local/root/lib
cd root/tutorials/
Now the problems.
I have always started the X server with the option '+bs', i.e.
XWin -multiwindow -clipboard -silent-dup-error +bs
(for example with a startxwin-2.bat which differs from the default
only by '+bs')
It enables the 'backingstore' which enable the 're-display' when two X
windows are overlapped (otherwise they appear corrupted).
With X11R7.4 here is what happens:
--
$ root
[...]
root [0] .x hsimple.C
--
At ROOT prompt (root [0]), you have to type '.x hsimple.C', which means
run (.x) the macro hsimple.C; hsimple.C is a block of C/C++ code
which ROOT executes as an interpreter.
Well, after this, not only ROOT segfaults, but also the X server
segfaults!
If, instead, I DO NOT start X with +bs, i.e. if I use:
XWin -multiwindow -clipboard -silent-dup-error
(for example with the default startxwin.bat), the above example and
others work fine, but...
Many ROOT tutorials/examples are OpenGL applications, for example
'geom/shapes.C'. In this case, only ROOT segfaults as follows:
---
$ root
[...]
root [0] .x ./geom/shapes.C
root [1] Error in RootX11ErrorHandler: BadMatch (invalid parameter
attributes) (XID: 14680185, XREQ: 62)
assertion !c-xlib.lock failed: file
/usr/src/ports/xorg/libxcb/libxcb-1.1-2/src/libxcb-1.1/src/xcb_xlib.c,
line 73
Obviously, under X11R6.99 all the above works just fine.
cygcheck.out and XWin.0.log attached.
Cheers,
Angelo.
