[PyQt] Possible Issue with PyQt on Amazon EC2 Instance

[Kevin Hu]

Dear All,

I want to use Ghost.py, a headless webkit using PyQt, on an Amazon EC2
instance with a centOS distros. I have installed X11, Xvzb, Qt 4.6, and
PyQt4 via yum. However, when I try initiating an instance of Ghost, I
receive the error:
-------------------------------
Fatal server error:
Server is already active for display 99
If this server is no longer running, remove /tmp/.X99-lock
and start again.

loaded the Generic plugin
can't make "generic.orientation" because no QAccelerometer sensors exist
-------------------------------
When I kill process Xvfb :99, and try again, I receive the error:

ghost: cannot connect to X server :99
_XSERVTransmkdir: Owner of /tmp/.X11-unix should be set to root
[echonest at ip-10-4-85-75 ~]$ expected keysym, got XF86TouchpadOn: line 120
of inet
expected keysym, got XF86TouchpadOff: line 121 of inet
-------------------------------

Would you say this is an issue with PyQt? How would you recommend I proceed?

Sincerely,

Kevin
