Ubuntu: Black Login Screen after installing updates 12.04



Question:

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 have tried typing in weird commands but they didnt do much like sudo start lightdm and sudo startx .. didnt do anything just froze.. i dont exactly no what these commands do but something to do with black screen..so i thought id try it..

Thanks


Solution:1

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/fglrx-uninstall.sh  

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


Solution:2

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..


Solution:3

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...
ctrl+alt+f8
ctrl+alt+f7
