[X2Go-User] X2Go TCE problem

Hello list,

I use http://wiki.x2go.org/doku.php/wiki:advanced:tce:install as my guide to install X2Go TCE on:

• Linux Mint 17.3 MATE x86-64 as X2Go Server, and
• Debian 7.90 as PXE server (both are VMWare VM).

Booting my thinclient I got boot menu: X2Go Thin Client Environment

• Boot from local harddrive
• X2Go Thin Client
• memtest86+ (run memory test) Press [Tab] to edit options

When I choose "X2Go Thin Client", it just only showing text mode login as below:

Debian GNU/Linux 7 x2gothinclient tty1 x2gothinclient login: _

Do I possibly missed something in my config?
