This is XFCE 4.10 on Xubuntu 13.10. An experiment really..yes it is blue decked and that is awesome, but that wasn't...well
anywho
The idea was..can I just point the installer to my SD for root, and keep home(s) on internal. I haven't done that yet, this is all SD, but I have to wipe to attempt..soo..look at my awesome Blue decked XFCE!

Also..4.12..uhhh..Nooo
So looking at that, yes, you can get the applications, you can install the 4.10 ppa, then the 4.12 ppa(yes, you have to have both), you can pull the source and compile, but that is not the latest XFCE. That is pure development. I am not sure what went wrong, but is a few months overdue from actual release, and there are no indications when it will be.
