My computer boots to a black screen, what options do I have to fix it?
After installing Ubuntu on my fresh desktop, the Ubuntu loading screen shortly appears and then I get a black screen. After that the screen is split into two.
The image begins at the middle and then continues over the left half of the screen. I have a Radeon 6850HD with dual monitors connection, has it something to do with this?
When booting in failsafe mode, I get a message that Ubuntu failed to load failsafe video drivers. I am able to start a live session though. So I guess it loads the wrong drivers upon booting from hd. I think maybe editing the xorg.conf file could help, but until now I did not succeed.
I cannot comment (I don't know why) so I answer as far as I had similar problem with Ubuntu 12 and my nvidia card. What I did is to install the alternate distro and when I had to reboot I chose the recovery mode, set up network, return to main menu and finally update whatever I could.
