* The remote desktop solution in Ubuntu uses the VNC backend which can't
read from hardware accelerated displays.

When I initially connect to the vino server, it gives me a snapshot of
the screen as I connect to it, it's just not feeding the updates.
Doesn't this suggest it *can* read the display memory from hardware
accelerated displays? I *know* wobbly windows works through a VNC
viewer, albeit a bit jerky, as I had it working at one point, so I'm
sure it's possible (whether that was with nVidia hardware or not I don't
recall).

Re: adding a notice for users. Looking at the other comments on the
ticket, and from my own experience, I'm fairly sure that this bug is
simply a regression in something that used to work fine a few years ago.
It's not a whole new problem we suddenly have to face, it's just gone
unfixed for a long time. For that reason, hacky scripts that tell users
that Ubuntu/Linux can't do something (that it used to be able to) and
instead tell them to 'go reconfigure!' should be avoided *at all costs*,
IMHO. Not only does it look bad to users, but it would be a massive
waste of time/resources as it would mean more UI code would need to be
written/tested/discussed/translated/approved/released/maintained etc.
(all in a short time frame, by a large number of people, to get it into
the upcoming release!) as a workaround - only for it all to become
redundant the moment this bug gets investigated and resolved by a
capable developer who's familiar enough with the code to fix it.
