http://askubuntu.com – The details are that I used Universal USB Installer version from pendrivelinux.com to install ubuntu 12.10 onto a 4gb pendrive as per instruction on Ubuntu's website. However, after I boot with drive I am met with the following message: "The system is running in low-graphics mode. Your screen, graphics card, and input device settings could not be detected correctly. You will need to configure these yourself." Pressing Ctrl Alt F1 doesn't allow me access and the options on the dialog box either send me through a loop returning me to the previous dialog or just leave me dead in the wat (HowTos)
