Binary package hint: xorg
Hello, I plugged my wife's computer (running Vista) into a projector and
saw it automatically detect the projector and it's resolution then set
the laptop's screen res to that resolution and enable mirroring. No
interaction required. I definitely got jealous.
Right now when you plug in a projector to Ubuntu nothing visible
happens. In recent releases things have improved greatly but we could do
one step better.
I don't know if xorg can detect the difference between a projector and
an external monitor, but assuming it can't tell, I can think of three
use cases where someone plugs in:
1. They want a second monitor to extend their desktop
2. They are doing a presentation using a software package like OOo and they
want different views on the computer and projector screens
3. They are doing a presentation and want the same view (mirroring) on the
computer and projector screens
So for most presentations either option #2 or #3 is equally suitable. If
you plug in your projector and #3 happens automatically you will
probably just go with it and be content. You saved some time and
fiddling, and in the cases of meetings where there are multiple
presenters (for example a user-group meeting) that extra minute of
fiddling between presenters can be frustrating (30 sets of eyes staring
at you trying to get your OS to work).
In those cases where you really wanted #1 or #2 and mirroring won't work
you're no worse than you were with the current situation of having to go
to the display settings program and extend your desktop onto the second
screen. In fact, you're probably slightly better off with the mirroring
because then you at least know things are working right away. (i.e. you
get a visual confirmation when you plug the second monitor in)
