[Discuss] runlevel 5 service cannot connect to display

[abreauj at gmail.com (John Abreau)]

I've always found Exceed to be clumsy and cumbersome. I found a
free-as-in-beer
alternative long ago that's much lighter-weight and works well with putty;
it's called
Mocha-X, and it runs as a service in the system tray on XP, and the
equivalent
on Windows 7.
