I am writing some code using OpenGL, and when run under Xvfb on MacOS it dies, 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: 17 Current serial number in output stream: 19
There are a number of different reasons for which XCreateWindow() would return BadMatch. Check the man page.
I think MacOS uses the XFree86 version of Xvfb, but my first question is how can I tell for sure, and how do I determine which version I've got?
The XFree86, or X.Org, version associated with Xvfb should at the bottom of Xvfb's man page.
(I note that on the MacOS system I have access to here, X support is a mixture of various XFree86 and X.Org versions.)
