Troubleshooting

The Problem:

I'm running 10.04, and it suddenly started freezing after it boots. I can move the mouse, but I can't select anything. When the problem first started, there were only two things on the screen:
1. Gnome-Do
2. "Unlock Login Keyring" dialog box

What I have done thus far:

Asked myself if the keyboard was plugged in :-) Yes, it is.
Tried to use ALT+F2 or CTRL+ALT+F1 per the "What Should I Do When Ubuntu Freezes" question. (Neither were responsive)
Tried to reboot using the REISUB method (which did reboot, but I still had the same problem upon restart)
Gnome-Do was in the autostart folder, and I removed it by deleting ~/.config/autostart/gnome-do.desktop
Deleted my password keyring per this blog post
Tried to kill and restart X with ALT+SysReq+K (Screen went black but X didn't restart)
Tried to hit the Esc button

What my screen is currently showing:

My screen currently shows the "Choose password for new keyring" dialog box.
