I've been using X2Go for a while now to connect from Windows10 to remote Ubuntu server.
I've been using the X2Go Session Type "Connect to local desktop".
Everything was working last night. Today when I tried connecting the X2Go Client seems to connect. However, where the X2Go Client GUI normally displays the Ubuntu desktop, I get a black screen which temporarily shows X2Go logo/name.
There are quite a few pages related to X2Go Black Screen, but I couldn't find an answer to my problem. Here are a few I looked: x2go do not connect to active desktop session X2go Black Screen
While ssh'd into remote machine using putty simultaneously while X2Go client is connected and showing black screen, if I run x2golistdesktops from terminal, I see
theusername@:50
theusername@:1
I think the theusername@:50 is the X2Go connection. This concerns me b/c in info reported by X2Go client (see below) I see Info: Forwarding X11 connections to display 'localhost:0'.
I've tried restarted my local machine. I've also restarted the X2Go service on the remote Ubuntu machine. I was also able to connect to remote machine using putty with x11 forwarding and xming and get GUI (e.g. for emacs).
Here is info reported by X2Go:
