Xvfb and the composite extention

[Irek Szczesniak]

I would like to run Xvfb with the composite extention enabled, and
therefore I want to ask two questions.

First, it is posible to run Xvfb with this extention?

Second, if so, how to do it?

I tried running:

  Xvfb -x Composite :1

but it doesn't work.  I tested the composite functionality with the
uncover program available at:
http://cvs.freedesktop.org/xapps/uncover/
but I get this error:

  ~/uncover >./uncover
  error 2 request 78 minor 0
  error 8 request 1 minor 0
  Segmentation fault

This program works under a regular X server with the Composite
extension enabled.

Thanks for reading!  Any advice is very welcome.


Best,
Irek
