I had installed several updates and now Ubuntu 12.04 will not boot at all. It brings me to the login screen. I login and the screen goes blank. Help...

I found this blog helpful in the same situation so I thought I'd pass it along.

I could boot up to Stopping System V Init Process, which meant all of the services had started and the only thing left is the gui. I tried dpkg-reconfigure and booting to a older kernel in grub and none of that helped. I could start a VM headless so virtualbox was working. I use xfce4 and its much better than the default desktop.

Also, try to boot previous kernels by selecting Previous Linux versions from grub..

The default Unity and its companion compiz really stretch what graphics software and hardware can do. Even if you had an earlier version of Unity working, it might be worthwhile to try Unity 2D, or one of the gnome shells.

At the login screen, before you enter your password, click on the icon there next to the userid you are signing on as. Click Unity 2d and then enter your password. Unity 2d is, in effect, a backup mode for when there are problems.

Even if you would like to run the full Unity, doing this might help determine if advanced composition and rendering are involved in getting the blank screen.
