Downloaded Ubuntu-tweak to give it a try, and found some interesting settings. The only thing used for now is:
“Startup” – “Autostart”
Disabled Bluetooth Manager and Visual Assistance since I don’t used them
“Applications” – “Third Party Sources” -
Added the Google Linux repository
“Applications” – “Add/Remove”
Added VLC Media Player (which I have been missing). Noticed that “Ubuntu Restricted Extras” (which I wrote about here was easily availble from here, same thing with XBMC)
