You have ignored my cygchec.out here [1]. I have those packages
installed and glxgears, glxinfo seem to work (see opengl.txt below).

The fact that also XWin segfaults, means it isn't a problem only for
ROOT developers...

Just for completeness, I have tried and IT WORKS JUST FINE and without
XLIB_SKIP_ARGB_VISUALS! 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...

Cheers,
