Unity wallpaper settings for dual screen wallpapers.
This is what the Ubuntu Unity desktop looks like with a dual monitor configuration. The launcher bar is on both desktops; but the dash when clicked on either desktop is independent of the other. And the wallpaper will span both desktops. This is on Linux Mint 14 and it is clear to see that this does work pretty well after all. Unity is not the best desktop to run on Linux but from the looks of this it appears to function pretty well with a dual monitor setup. This is pretty interesting. I have the dual monitor configuration set up in the xorg.conf file and every desktop I have will adopt this configuration; but some work better than others. I installed Windows 7 Enterprise from scratch and after installing the display drivers I was able to configure the extended desktop very easily. Linux should come with its own simple GUI tool that can configure the dual monitor configuration and write an xorg.conf file with the proper configuration settings put in automatically. That would be very helpful when you are setting up a Linux distribution and you have multiple monitors. The ubuntu-tweak utility does not have any facilities for configuring multiple monitors with Unity though.

This is how I configured my dual screen setup on Linux Mint 14: http://www.securitronlinux.com/bejiitaswrath/linux-mint-14-dual-monitor-support-works-after-all-with-ati/. This configuration with the ATI hardware works perfectly. And here is how to install the ubuntu-tweak utility on Linux Mint 14 and Ubuntu 12.10: http://www.noobslab.com/2012/10/install-ubuntu-tweak-081-in-ubuntu.html.
I am a computer enthusiast that has always been interested in maintaining and upgrading computer hardware. I was born on a farm and lived there for 13 years before moving into town. I was always interested in technology and my father always gave me good encouragement for developing my knowledge and interest in tinkering with computers. He was using a computer on the farm but that was in the very late 80`s and late 90`s. Seeing what a computer could do always fascinated me and then I knew that is what I wanted to do. The first time I used Linux was Red Hat 6.2 installed off a single CDROM and I was amazed that you did not need to install any more drivers on my old Intel Celeron machine to be able to enjoy a nice 24BPP desktop and use the GIMP to edit photos and enjoy playing the old Linux games like Xbill. Then a while later I tried Mandrake Linux 9.2 and I was hooked. It came with so much software and was very easy to use as well. Then Mandrake Linux 10 and on through FreeBSD, Debian 3.0, Debian 3.1 Suse Linux 9.2, Suse 10 and onto the Ubuntu distributions although I am using Fedora Core 15 and the Gnome 3 desktop at the moment.
