I have quite a famous problem as it seems: while booting, the computer displays Checking battery state... [OK] and then hangs.
* Starting CUPS printing spooler/server
mountall: Plymouth copmmand failed
mountall: Disconnected from Plymouth
[...]
speech-dispatcher disabled; edit /etc/default/speech-dispatcher
JMX enable by default
[...]
* Starting NTP server ntpd [ OK ]
saned disabled; edit /etc/default/saned
* Checking battery state... [ OK ]
All the answers I could find mention pressing Ctrl+Alt+F1 and entering my credentials. But after doing so, I just get as an answer login incorrect and I'm again prompted to enter my credentials. I am 200% sure about my credentials, I have been working on this machine for over 3 weeks logging in and out around 10 times a day.
