Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free, no registration required.

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.

If your Ctrl+Alt+T command works maybe it means the Unity is having problem to start. The solution below worked to me: askubuntu.com/a/244064/123806 –  Gabriel Jan 16 '13 at 23:44
