Getting started information for ubuntu 13.04 on BBB (similar to Angstrom)

Hello All ,
I have downloaded ubuntu-raring-13.04-armhf-3.8.13-bone20 from & installed on SD card. It started fine.

Is there any documentation on how to SSH to PC through USB0 (same as angstrom), changing resolution of screen through command line?

Because I have no LAN internet connection , so I could not install ubuntu-desktop.

Is there option to use following commands (same as Angstrom).

  • /sbin/route add default gw
  • echo “nameserver” >> /etc/resolv.conf

By this way I can get connected to USB dongle through SSH into PC.

Please help
