With Ubuntu 12.10 everything was perfect. A few days ago I upgraded to version 13.04 and only gives me problems.
With 13.04 I saved what I do after rebooting. For example, Firefox bookmarks disappear and I have to recreate them. Icons or programs that put in the left margin (favorite programs) also disappear when the computer restarts. All that I have saved in Downloads also disappears ...
I want to know if I can return to the version 12.10 or 12.04 , and what would be the easiest way to do this, because I don't have many computer skills. Thanks
