I have the same issue. When I switch between the screen of my laptop and the external monitor, the background of the external one suddenly changes to blank white sometimes (the background colour of the launcher on the external screen doesn't change but the notable objects from the wallpaper shown below the launcher aren't there so the launcher keeps the colour but misses the background image). Right click on the blank white screen shows the menu and icons are visible as well. I think it's not a duplicate of bug #1241252: the top menu bar doesn't change. I'm not sure it matters but according to lshw, I has an nVidia GT218M [NVS 3100M] and I use the binary 319.60 driver (nvidia-319-updates). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1241258 Title: wallpaper doesn't span across multiple monitors, white background shows instead To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nautilus/+bug/1241258/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
