Updated Ubuntu 12.10 and now all I have is a black screen

[SUPERFITTER]

I updated Ubuntu 12.10 and now all I have is a black screen after repeated reboots. Does anyone else have this problem? If so how did you fix this problem?

Hi SUPERFITTER.

Do yo have any proprietary graphic driver installed?

Regards.

[SUPERFITTER]

I have a duel boot with windows 7 and have a Radeon HD7770 Card with driver. Everything was working perfectly until I updated.

Are you able to see the grub menu?

If so, I assume you are getting a black screen after selecting Ubuntu?

Yes to both. Thank you for the help

Hi --

Just a quick question before I leave you again in papibe's capable hands...

Did you update or install fresh?

If you updated without first disabling the driver for your graphics adapter, that could be part of the problem.

Best wishes!

This was a fresh install that I did a couple of months ago. Now I just updated like I have done in the past. How do you disable the driver for your graphics adapter?

Thanks. That looks like good news.

Once you get to the black screen, wait a minute or so, and press Ctrl+Alt+F1 to get to a text-mode console. There you can login as you.

Once you get to a terminal, run these commands:

sudo service lightdm stop

sudo mv /etc/X11/xorg.conf /etc/X11/xorg.conf.old

sudo service lightdm start

If everything goes well, you will get to the graphic desktop.

Let us know how it goes.
Regards.

When I booted into Ubuntu I got the desktop picture and that changed from the black screen. I then got a terminal and followed your code. As soon as I got to sudo mv /etc/X11/xorg.conf /etc/X11/xorg.conf.old it said that there is no file by that name. I did it twice and got the same results? I will have to continue tomorrow, time to bed for me. Thanks again for the help

I see.

Let's try again. You don't need to reboot as long as you are able to go back to the console using Ctrl+Alt+F1.

I'm still assuming it is a graphic driver problem, so let's remove the proprietary driver (you can reinstall it later).

sudo apt-get remove --purge  fglrx  fglrx-amdcccle  fglrx-updates  fglrx-amdcccle-updates

sudo reboot

Let us know how it goes.
Regards.
