Having done some minor resettings on alsamixer with no results, I
thought I had to reboot.
But : "Oh no, something has gone wrong..."
So, I am writing this message from my other laptop running Ubuntu 14.04
I tried to reboot in rescue mode, but I don't know what to do from
there. 'startx' says that it doesn't have the proper files to launch
startx as root.
login
bd
says : wrong login (doesn't even ask a pswd)
It's unclear how far you're getting.
Can you boot normally and get to a login prompt on a text-only screen?
