I have a beloved high performance 10.04 LTS 64 bit workstation, where I do serious work. I am considering doing a release upgrade to 12.04 LTS early. It seems that 10.04 LTS is not fully supported as I have to manually install a Nvidia driver, the nvidia-current not supporting my year old video adaptor.
I make heavy use of multiple displays, Gnome panel applets and the Desktop Cube, Rotate Cube and 3D Windows in the way I work. I find Unity obstructive to my style of working, are these features available after upgrading to 12.04 LTS?
