The rgl package currently crashes R when running under Xvfb (the
"virtual frame buffer" server), at least on MacOSX. It makes sense that
it shouldn't be able to work there (it needs interactivity), but I don't
know how to detect the problems before they cause the crash.
Currently the error happens the first time you try to open an rgl
window; when rgl calls XCreateWindow R crashes with the error message
X Error of failed request: BadMatch (invalid parameter attributes)
Major opcode of failed request: 1 (X_CreateWindow)
Serial number of failed request: 28
Current serial number in output stream: 29
I've checked and as far as I can see all the parameters we're sending to
XCreateWindow are valid, but I might have missed something: I don't
know much about X11 programming. (The call is
::Window xwindow = XCreateWindow(
xdisplay, RootWindow(xdisplay, DefaultScreen(xdisplay)),
0, 0, 256, 256, 0,
xvisualinfo->depth,
InputOutput,
xvisualinfo->visual,
valuemask,
&attrib
);
but without context that's probably not worth much to others.)
Are there any experienced X11 programmers out there who can suggest what
to do next?
