Unity is very controversial product. There are as much people who love it as people who hate it. Nobody stays aside. You love it or hate it (Marmite).
But do you know that Ubuntu 11.04 comes with 2 (two!) desktop environments? It also includes GNOME. To be precise, GNOME 2.32.1.
Let me show you how to easy switch from Unity to GNOME.
There are 3 easy steps to follow in order to move away from Unity in Ubuntu 11.04.
1. Call up application "Login screen". You need to unlock it for editing purposes and then ensure that radio button is switched to "Show the screen for choosing who will log in" position.
You may wish to switch to "Ubuntu Classic" on same screen, but from my experience this does not help.
2. Call up application "Users and Groups". Select your username and ensure that Password is set to "Asked on login". If not, you need to click on "Change" button and then untick checkbox "Don't ask for password on login".
In other words, steps 1 and 2 ensure that you get password entry screen during the boot of Ubuntu 11.04.
3. Reboot. When you are asked for password, look at the bottom of your screen. There is a panel with drop-down options. Select "Ubuntu Classic" there. Then enter your password and hit "Enter".
4. Enjoy! You are now in Ubuntu 11.04 with GNOME desktop!
Your choice of desktop environment for Ubuntu 11.04 is now remembered. If you wish, you can switch on auto-login options which we disabled in steps 1 and 2.
Unfortunately, this trick is only available in Ubuntu 11.04. Next version Ubuntu 11.10 Oneiric Ocelot will only be shipped with Unity desktop.
Do you want to try Ubuntu 11.04 yourself, but cannot download image and burn it to CD yourself? You can check the page Buy Linux CDs and make an order there.
