[Desktop12.04-Topic] Multi-screen setups

[Dereck Wonnacott]

I use a laptop with an external monitor on a daily basis, I've upgraded from
11.04 to 11.10 in hope of finding better multi-screen support but was quite
disappointed.

My laptop has an Nvidia card and I was not able to activate my external
monitor with unity 3D. [BUG 864784]  HOWEVER, Unity 2D is surprisingly
pleasant! I don't feel like I'm using second class software in the
slightest. In fact, I rarely notice that I am using unity 2D. It's terrific,
thank you guys!

I miss the window snap function on the shared edge of the screens. Snap only
seems to work on the far edges of the workspace.

I would REALLY like display hot-plugging to turn on my external monitor when
it's plugged in, but I've adjusted to using the nvidia-settings tool every
time I boot my laptop.


As for the questions posed by Bryce, here's my two cents as a user:

I'd be much happier if unity reflected the application use on that screen.

yes!

Perhaps as the mouse approaches the top left corner of the screen, it could
slide out much like how the the window snap works.

I think it makes the most sense to follow the mouse, rather than mirroring
on both screens.
