I'm currently running ubuntu 13.10. I have an nvidia graphic card and two monitors (VGA and DVI). The monitor I use as the main one is on the right, and the launcher is indeed on this screen. The problem though is that the desktop icons are aligned on the left screen (the secondary one), and this is very annoying. I'd like to have the desktop icons aligned on the right (main) screen.
I am using mdm as desktop environment but I wouldn't mind changing it to solve this issue (I currently tried mdm, lightdm, gnome) with no success.
I googled the issue a lot, and I only found old threads that basically stated that it's impossible, but hopefully someone has some good news for me.
