TigerVNC xfce config

Hi everyone,
I’ve been struggling since days to use latest TigerVNC, i finally get it to work but there is a glitch while using ~/.vnc/config file.

session=xfce
geometry=1920x1080
localhost
alwaysshared

I have remove it to be able to use TigerVNC :thinking: What can be the issue with it ?
