My computer boots to a black screen, what options do I have to fix it?
When I startup my Ubuntu 12.04 installed on a Z77 Pro4 (ASrock motherboard), crucial M4 SSD drive (sata 3), and intel i5 3570k (ivy bridge), I get this black login screen :
I also hear the ubuntu login sound "tic toc" but the screen is black, and if I type in some text, only strange characters appears (as you can see on the picture).
Do you have any idea ?
Thanks.
ps : this is an evolution of a previous problem exposed here
