Hi dave,
Toorox live cd boots with auto login!
You need no passwd !,
When booting stops , on the point: type in a user and a passwd, it is a problem with your grafic card.
Reboot and in the first boot window( 15", 17", e.g)
Look for the right monitor size and hit the TAB key!
Insert:xmodule=vesa for standard driver, or xmodule=nvidia for example:) on the end of thr line!!
And boot toorox!
Kind regards
Fynn
