i'm still new to linux and have been testing it out on my laptop.
i ran updates on ubuntu 12.04lts and something failed along the way. after reboot, when i log in, the screen is blue and the icons and taskbar are not displayed. i cannot even open up the terminal.
sudo apt-get install ubuntu-desktop and that fixed the issue, however, i am only limited to ubuntu at login. the ubuntu-2d option (unity-2d) is now missing. i tried reinstalling unity-2d with
sudo apt-get install unity-2d and to no luck.
sorry i'm a newb. any advice is welcomed.
