When I turn on my computer (a CR-48), I keep loading tty1. I have tried xstart, and all I get is:

Fatal server error:
Could not create lock file in /tmp/.tX0-lock

When I attempted to make the directory (both sudo and not), I received these two errors:

sudo: Can't open /var/lib/sudo/don/tty2: Read-only file system (I've gotten other tty's for different virtual terminals)
mkdir: cannot create directory '/tmp/tX0-lock': Read-only file system

Before I got to the only terminal state, I had the computer moving a few files from a network server to the computer, I put it to sleep without stopping the transfers, and started the computer again away from my home network, and attempted to stop the transfers, the computer than restarted.

Running sudo reboot puts me right back in the virtual terminal, and I can't get into any sort of x application.
