Thanks for your fast response Stefan, and my apologize for the inconvenience of my previous email.I run this command after log in as root to TCE:# startxError:xauth: file /root/.Xauthority does not exist# touch /root/.Xauthority# startxAnd then system brings me to X text mode.Then I run x2goclient manually, I can connect and log in to X2Go Server.Regards,PopungOn Fri, Jun 3, 2016 at 2:46 PM, Popung <popung@gmail.com> wrote: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 optionsWhen I choose "X2Go Thin Client", it just only showing text mode login as below:Debian GNU/Linux 7 x2gothinclient tty1x2gothinclient login: _Do I possibly missed something in my config?
