After the fifth attempt to install 12.10, I finally got the Nvidia graphics driver installed so that I could began to get my desktop set up. It took a lot of reading to determine what secret steps I needed to pursue to accomplish installation. Previously, I would try, fail, and go back to 12.04.1, but it kept bugging me that I couldn't get 12.10 up and running. I thought things would now proceed much better.
I discovered I couldn't set up my fonts (what happened to gnome-tweak-tool), and I couldn't set up my monitor (no nvidia-settings color , contrast adjustment, etc.), inability to move the windows-controls from right-side to left, etc..
I decided this was ridiculous - I don't need to re=learn how to do these things! I've been using Ubuntu/Kubuntu since version 6.10. I've tried other distro's from time to time, but always come back to Ubuntu. No more. I've installed Linux Mint 13 (MATE) which works fine. I know Mint is a "dressed-up" Ubuntu, but I will continue to use it. Since its release date is a month later than Ubuntu's many of these PTA's will be worked out.
It's time the developers concentrated on getting better performance OOTB.
