[Pxc] Problem

Your display access problems are solved, it seems.

good.

> Do pxc_xgrab:

Than it looks like you have some problems in the "open()" system call.
What do your kernel messages report? What does "strace pxc_status"
report?

There's nothing in "pxc_open()" that retund EINVAL (invalid argument).
