So, I am an Ubuntu newbie, and I don't know a thing about it. I tried to install restricted extras (am I using it right?) through terminal, but it seems I failed :) maybe because during installation the internet connection crashed... anyway, I restarted and I got the Ubuntu intro screen at the boot, and then a black screen appeared with this information:
checking battery state
I restarted and it showed something else, so I rebooted for 5 times. Then a screen appeared
*starting bluetooth *pulseaudio configured for per-user sessions saned disabled; edit /etc/default/saned
I tried this: My fresh installation doesn't load. (PulseAudio problem) but didn't know how to save so I just skipped to update-grub, anyway nothing helped. What do I do?
