Any button.. sometimes when I click "settings" on a VM, sometimes when
I'm adjusting settings, sometimes when I click "run", but always the
second I click something - it never just dies when my back is turned.

I do - I'm using VRDP to each VM, which works very well. I have
sourced a nice script that starts the machines I want when the host
boots. I'm quite familiar with the day-to-day start and stop command
line, and can muddle through the more complex admin and create
functions, but I'd *rather* not.

So why is there VNC in the first place? Because there *is* a GUI that
people *want* to get to - 'wants' and 'needs' are different :-)

The answer to "does anyone know why VNC keeps crashing?" is not "it
won't crash if you don't use it".
I want to be able to get to a (reliable) GUI over the network. Do you
know how I can achieve this (with VNC or otherwise)?

Yes, as will "reboot" - but I can't remote desktop on again until I've
plugged a monitor into the console and logged in as a user - this it
the concern I'd rather not have (not "how do I reboot an Ubuntu
machine from the command line?").
