Hi,
There is a student working on multi monitor wallpaper support for Nuancier.
That we provide at least dual monitor wallpaper, was more then once requested on us.
There are currently 24 different variations for resolutions, some might not be from interest. The problem is simple even when it are only two monitors, we have to produce a huge variety of different wallpapers. Its not just produce two wallpaper and leave the scaling to the DE. Let me give you an example. Right now I working on a laptop with an resolution of 1024x768 and a second monitor is attached with 1920x1200 and he is standing on the left side. So only one possibility means 2 pictures, if I change the position of the monitor to the right side it are already 4. Not speaking that some developer have often an attached monitor in portrait mode for reading documentation.
What it means for us as Design Team means, we have to decide if we want to provide dual or multi-monitor wallpaper for the default wallpaper and then produce just one picture large enough and the user can go to Nuancier and get the right resolutions by them self.
