Have you tried Ubuntu 11.04 yet? What do you think of the new Unity interface? I happen to like it, but it certainly isn’t for everyone! There is some learning curve to it and it can be buggy (or at least seem buggy compared to normal –aka “Classic” — Gnome usage)…
I know my friend Brad isn’t the only person who wants to know this and I’ve seen several confusing and excessive responses to this question, so I’m going to make it plain and simple for you all! And you get multiple options! Woohoo!
Ubuntu 11.04 ships with the new Unity interface as the default GUI, but it also comes with other options like “Ubuntu Classic” and “Ubuntu Classic (no effects)”. You can select which one you use from the login screen and/or set a different option as your default. See below for more.
Change at the Login Screen (may only be temporary)
One easy way is to simply choose “Ubuntu Classic” from the login screen*.
At the login screen, select the user you wish to login, type the password, but DO NOT press ENTER (or click Login) yet… Look at the bar on the bottom of the screen. See where it says “Unity”? Click that and change it to “Ubuntu Classic” (or use the “no effects” option if you have an older computer and/or video card).
Now you can login and you’re back to using Gnome (aka the “old” Ubuntu GUI). Depending on your system settings this may only be temporary. To ensure this is permanent see the next two sections.
*Note: If you have auto-login enabled, you will have to logout first.
Set Ubuntu Classic (Gnome) As Your Default GUI
Using the system settings (don’t be scared, it’s not as bad as it sounds) you can set Ubuntu Classic (or it’s “no effects” clone) as your default GUI. This is actually pretty easy.
Step 1: Click the system button located at the far top-right corner.
Step 2: Select “System Settings” (should be the last option) to open the Control Center
Step 3: Select “System” on the left side, then “Login Screen” on the right, to open the Login Screen options window.
Step 4: Click “Unlock” and enter your password (assuming you have sudo powers).
Step 5: Change the “Default Session” to “Ubuntu Classic” (or the vanilla “no effects”). Then close the window.
Step 6: Either log out and then back in, or restart your computer. Done.
Set Ubuntu Classic (Gnome) As Your Default GUI — The (slightly) Faster Way
Step 1: Click the Ubuntu logo in the top-left corner. (This brings up the “Search” overhead/hub)
Step 2: Type: “Login” (no quotes) then click the “Login Screen” launcher.
Step 3: Click “Unlock” and enter your password (assuming you have sudo powers).
Step 4: Change the “Default Session” to “Ubuntu Classic” (or the vanilla “no effects”). Then close the window.
Step 5: Either log out and then back in, or restart your computer. Done.
