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.
Otherwise, AS A NUMBER OF PEOPLE INCLUDING MYSELF HAVE TOLD YOU
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.
