Black screen after log in and sudden disconnect of TigerVNC Debian

[Gabriel Rodríguez]

Hi,

I have been trying to use TigerVNC to connect to a workstation, but I am having some issues. Everything seems to be fine until I log in with the password and the tab of my remote desktop appears. It does it completely black - with the usual message of "Press F8..." - and after 10-15 seconds the connection suddenly stops.  

This is the log.file I am getting:

I have the feeling the last two lines might be the ones pointing the problem, but I have unfortunately, I have been unable so far to solve this.

Thanks in advance for the help,
