Hi I have dual monitor in lubuntu. The main screen is 1280x800 and the extended screen is 1024x768. I installed variety. It changes wallpaper every 5 minutes. However it changes wallpaper only in main screen. In the extended screen the wallpaper stays always the same. It is the default lubuntu wallpaper. I tried to change wallpaper in extended screen using nitrogen but nothing happens. How to change wallpaper in extended screen?


Ok I found the solution.

I downloaded and installed disper-indicator. It is a .deb package. I installed it manually because I could not find it in repositories. Then I have set disper-indicator to run on startup. So now I click on disper indicator and I configure the dual monitors

Disper indicator can be found from this repository https://launchpad.net/~nmellegard/+archive/ubuntu/disper-indicator-ppa

I actually had this same issue on Lubuntu 14.04 and it was driving me crazy. I changed the desktop wallpaper multiple times and ways, including even using Nitrogen and SyncWall both mentioned here.

What worked for me was running the following:

pcmanfm --desktop-off

from a terminal window.

I hope that helps some wandering soul that is trying to set multiple monitors with different wallpapers. I found the help on an old archlinux forum of all places.
