The choices are so many that it is not easy to decide. For installing Gnome 3 check here. In my experience, the Linux Mint per say is somewhat slower than Precise Pangolin 12.04 with Cinnamon i.e. the same desktop used with Linux Mint. Therefore I decided to use Cinnamon directly on Precise Pangolin. This is how it is done:
On next log in choose cinnamon session and it is done.
Another way of installing cinnamon:
For any reason the above does not work or latest 1.4 version of cinnamon is not available from repository .deb package can be downloaded and installed. The link to 64 bit package is here and 32 bit package is here.
After much reluctance I installed Ubuntu 12.04 Precise Pangolin on my office Desktop. It was rather an upgrade as I was using 11.10 the last release. Now upgrading to Precise from Natty is really easy but not so easy therefore I shall cover that in another post. Here I intend to share my experience with Unity, which was not happy. The problem I faced was that it was not easy to reach to the running apps. The unity icons simply did not respond. On several occasions, when I triad to run apt-get from the terminal, it refused with lock error ‘another version is running’. It was too much annoyance. I use Ubuntu only to avoid such silly ‘window type’ error messages. Hence I decided to switch to Gnome 3.4. It is fairly simple. Open terminal and type:
sudo apt-get install gnome-shell
Say yes to next question and it is done. Log out. Next time before logging click on that icon of gear next to your name and select “Gnome’. You would be logged on to Gnome3.
BTW, to shut down press alt key and suspend option shall change to shut down.
