If you want to run an X application within a container, you should have 
a recent kernel with an af_unix sharing across namespaces, share the 
rootfs and hack lxc to share the ipcs. Where of course, isolation is 
reduced and lxc lose interest.

There are a few alternatives, AFAIK.

  * Create a new X instance within your container, so you can switch 
between your desktop with alt+f<nr>.

  * Launch sshd in your container and ssh -X myXapplication from the host
