Which NX Client are you using ? The proprietary one ?
If yes, how is your client session configured ? In order to run TDE 
through NX, I configure as follow:
- Under "General" tab, in "Desktop" section, choose "Unix / Custom", 
then click "Settings" button.
- In "Settings" window, in "Application" section, check" Run the 
following command", then type "/opt/trinity/bin/startkde".
- In "Options" section, check "New virtual desktop"
Validate the options and re-run the session.

I often use TDE through NX remote display under CentOS, it works without 
problem (I'm on local network, not cloud).
