[X2Go-User] connection failed error when connect to local desktop

[Jeffrey Zheng]

I have X2Go server installed on my Ubuntu 14.04 computer, and have X2Go
client installed on my Windows 7 computer. When I try to use "Connection to
local desktop" to remotely connect to Ubuntu, I will get a connection
failed error: "No protocol specified xwininfo:error:unable to open display
":0"


Can someone tell me how to fix this?

Thanks,

Jeffrey
