Ubuntu 11.10 basic GNOME Shell tweaks...

1) Install GNOME Shell and gnome-tweak-tool, then restart your machine and choose GNOME for your session

$ sudo apt-get install gnome-shell gnome-tweak-tool

2) Install Cantarell font

• Download font from here
• Copy font into /usr/share/fonts folder
• Run command below:

$ sudo fc-cache -f -v

3) Gnome-tweak-tool settings

• Desktop - turn off everything
• Fonts:
  
  • Default font - Cantarell
  • Window title font - Cantarell Bold

• GTK+ theme - Adwaita (default)

4) Remove overlay scrollbars

5) Fix Alt+F2

6) Disable Global Menu

$ sudo apt-get remove appmenu-gtk3 appmenu-gtk appmenu-qt

7) Change LightDM background via LightDM Manager
