The two things I do every time I upgrade Ubuntu
Every time I upgrade Ubuntu it sets these two things back to the defaults. Here are the "quickest ways" I've found to put everything back to normal. One note, before upgrading, know where you saved your wallpaper image, that'll get blasted away as well.
1. Layout, more specifically the "Gnome Classic" layout. Ubuntu 11.10 ships with the Unity desktop, and GNOME 3 in its repositories, aping the looking of the ‘old’ GNOME desktop is easy. All that’s requires is installing a few extra packages and performing a tweak here and there.
1. Paste the following line into Terminal:
sudo apt-get install gnome-shell
2. Next, log into the ‘GNOME Classic (No Effects)’ session from the Ubuntu login screen.
2. Buttons to the Right: How to move the Minimize, Maximize & Close Buttons to the Right in Ubuntu 11.10 (Oneiric Ocelot)
This is the simplest way i've found to move the buttons
1. To get started, press Ctrl – Alt – T on your keyboard to open Terminal. When it opens, copy and paste the commands below to move it...
2. Paste the following line into Terminal:
gconftool-2 --set "/apps/metacity/general/button_layout" --type string ":minimize,maximize,close"
Enjoy Ubuntu.
