This is not the place to discuss this but hopefully Management will 
allow a single message through, after that we will need to adjourn to 

There are three ways of running VNC. The first- and most common- is to 
start it up to look at an already-running session for remote support 
etc., which is probably what you've done.

The other two start it up listening to a TCP port, one way is to use 
inetd.conf and the other is to use inittab /but/ this latter doesn't 
work on Jessie or later (there might be an equivalent way to plumb it 
into systemd but I've not managed yet). Either of these ways will start 
up a new copy of the system's default display manager (lightdm or 
whatever), and at that point you can log in as an arbitrary user with 
your usual desktop... it is probably this that you're missing.

REPEATEDLY, you can quite simply run Lazarus- and I mean Lazarus, 
complete with its GUI stuff- over SSH. This is by far the simplest way, 
although as I've said elsewhere there can be a performance impact.

If you want to continue this, please start a thread in either fpc-other 
or lazarus-other asking about running Lazarus remotely.
