Totally unable to start the user mode
I've been using Kubuntu for 3 or 4 months without problem, but the other day, booting my computer, it just wouldn't start... So the computer is booting, but instead of accessing the user mode, they keep me on the black screen and ask for my login and password... As I do, what appears is like official information of Ubuntu, saying there's no warranty for the program, giving an email to write to if I have any problems... And the last line says: jeremie@jeremie-laptop: ~$
And then I'm supposed to write something... How can I just start using the computer?? I'm the true definition of a dummy regarding that stuff, so I have no idea... can anybody help??
Thanks a lot!!!
