Monitor Trouble when Booting
I'm completely new to Knoppix (minimal experience with Linux of any sort), and Knoppix seems to boot fine until it tries to display the GUI. My monitor gives the following error:
Out of range:
H. Frequency: 17KHz
V. Frequency: 21Hz
EDIT: It's a Viewsonic VA1912wb

Have a look at the Cheat Code documentation here: http://www.knoppix.net/wiki/Cheat_Codes
I would look at the xvrefresh and xhrefresh options and try to specify parameters that are compatable with your Monitor. 60 hz might be a good starting point. There is a cheat code that worked in the past for some monitor issues, "knoppix noddc" that may not be in the documentation. It's also worth a try. Be careful to use the proper syntax when using cheatcodes. You usually need to type "knoppix" and then the cheatcode(s). There are a few examples in the Documentation at the above link. There are more subjects covered in the "Documentation" link at the top of the page. It makes for some interesting reading.
