i ugraded from 12.04 to 12.10 and at first i was perfectly happy with it. but over the pasttwo momths or so i have become increasingly frustrated wit it. virtualbox wont work and i have tried every solution i could find at least twice, i cant get avant dockbar any more and a whole host of other really annoying stuff has just made me decide to throw in the towel with 12.10 and go back to a version that works. is there a way for me to be able to just switch back without losing all my files or am i going to have to bite the bullet and back up everything and just do a from scratch install of 12.04 again?
