--- Comment #5 from Carl Michal <michal at physics.ubc.ca> ---
I haven't tried this in a long time - I've been able to use hdmi generally -
and its always been reliable.

This computer now has a 4.11.3 kernel on it. I went down to the lecture theatre
just now with the apple VGA dongle and the situation is pretty different from
when I first posted this. In all of the rooms where I could reproduce the
problem, the projector switching system has been recently upgraded, so the
newer kernel isn't the only difference.

At the moment though, the apple dongle seems to work fine, as long as the
dongle is plugged into the projector switch before its plugged into the laptop.
If you plug the dongle in to the computer first, then plug the VGA cable in to
the dongle afterwards, it doesn't work.

If you'd like traces of those I can post them.
