High CPU usage vmware-user when freenx session started

[Puyal T. N. <np...@va...>]

Good afternoon

I have just installed a FreeNX Server on a Virtualized 32bit Ubuntu Desktop.
When a remote session is opened the vmware-user process created by the NX
login consume almost 100% CPU:

I would appreciate some help in order to debug why this happens and how to
solve it. 

Good afternoon
