I love my lixux 12.04..till yesterday it installed new updates and i clicked on restart..

As system went to grub all normal & loaded normal..then instead of pretty desktop (auto login turned on) i have black screen asking for login and password..

Why? How i get my desktop back to before?

Please help new noob!!! This is due to updates i am sure, nothing in hardware has changed and no other display settings changed.. using AMD diver from there site linux one for my raedeon 6850 and have catalyst driver working fine..

I tried your solution but it didn't seem to work. I removed my fglrx driver by the following command:

sudo sh /usr/share/ati/

And then my desktop came back after reboot. Then reinstalled ATI catalyst driver. Now, everything is working fine.

in that black screen, login with your username and password, and install gdm

sudo apt-get install gdm

that might solve the problem, I also had same problem when I did some things with my installation..

if that doesn't work (as indicated by some other source, try sudo apt-get install lightdm (gdm might have problem in 12.*) – Piyush May 30 '12 at 12:02

I have the same problem with Black Opal which is based on 12.04. Also switching to tty8 then tty7 seems to get you to the login screen with lightdm installed. I switched to gdm and the problems is gone, I just don't like how it changed the login screen to the old look...
