I installed Archlinux as Virtualbox's guest on Windows. After installation, I can not log in through GDM, though it lists my user name, and the root account doesn't work either. The error info is:
Sorry, that didn't work. Please try again.
Then I try to log in through command line, and
startx manually. This time it works, however, whenever I need to input my password in terminal, it doesn't recognize either.
How do I solve this? I am using Gnome 3.
