I have had problems with this laptop Aspire 4530 for the last 3 days. I erased the last Ubuntu (several times) and all is the same: Ubuntu starts, but in the screen there is not a menu (in the left side (using Gnome Desktop)) and I can not see any program, application, internet, graphic, games, nothing. I neither can see any folder. This is killing me for hours. Any idea in how can I get those menus back? Thank in advance
