Merge lp://staging/~lightdm-gtk-greeter-team/lightdm-gtk-greeter/greeter-background into lp://staging/~lightdm-gtk-greeter-team/lightdm-gtk-greeter/trunk

I've tested the latest changes in the branch. While it generally seems to work fine, it all depends on whether the user has set up his monitors correctly in Xorg. E.g. my work machine defaults to cloning/mirroring the outputs, so whatever I set in the greeters conf-file, I get a rather garbled output.

I'm wondering whether we shouldn't just handle the display layout within the greeter instead of relying on Xorg's default setup.

Also: how would the user change the default Xorg layout (without xorg.conf) easily for the greeter? (You mentioned xrandr before, but that's only within a user-session so it wouldn't affect the greeter, right?)

Ok, found the xrandr script for lightdm now.

As I said, this is far too complicated for the average user, I guess we should handle it ourselves by copy-pasting some code from e.g. xfce's display dialog/settings daemon.

(I guess that's the edge Ubuntu has over us with having gnome/unity-settings-daemon running in the greeter session already...)

Another update: after setting up the script, the branch does everything it promises. Awesome work! Especially the #cursor option is great and I'm thinking we should use it by default.

However, the whole thing of initially setting up the displays should somehow be simplified.

Sorry for so long response.

The best place for setting up displays (IMHO, of course) - "apply system-wide" button in xfce4-display-settings. It is the first place where average user will search for such settings.

I think it would be best if the greeter handled some basic monitor management. I'll think of some basic scenarios and simple code to add this in. In the meantime, this branch is approved for merging.
