[FreeNX-kNX] suspend session don't work

[Bobber Cheng]

Hi, all,

I use freenx-0.4.2 with gentoo and not install commercial nxclient. 
Everything work well exception suspend/resume. I found when i suspend a 
session, all applications are suspended, but the session go to failed 
session. Do i must use commercial nxclient to use suspend/resume.

Bests,
Bobber Cheng
