this morning I upgraded to ubuntu 12.10 from 12.04.
During the login (startup) screen everything is working as it should be. After I login the menu bar on top disappears and all I see is the background image.
I'm using a Samsung RC730 laptop with an Intel HD graphics card & a Nvidia GT540M which in windows switches automaticly using optimus.
I'm running the ubuntu 12.10 (64 bits version) and i CAN open the terminal after logging in.
I'm a new user to ubuntu so step-by-step help would be appriciated.
