Knoppix 6.2 runs where Knoppix 6.7 does not!

Greetings again, Karibu.

Cheat codes are another way of controlling Knoppix's behavior.
There is a five-second-or-so delay on every Knoppix boot that allows you
to interrupt the boot process to insert some instructions to modify certain
parts of Knoppix's normal initialization process.

The first keystroke, such as a letter 'k', interrupts this process until
either a time-out occurs or an enter key appears. Whatever is typed-in during
this interruption is examined and, if meaningful, is acted upon. On your CD or
in /mnt-system on most LiveCDs or LiveUSBs there's a file
/KNOPPIX/knoppix-cheatcodes.txt, which lists scads of these magic words.

What I and Klaus K are suggesting is that the next time you boot 6.7, you
try some of these cheat codes to see if any of these will help you get your
graphics set up better. Just try one at a time of course.

So, at boot, before Knoppix 6.7 goes ahead on its own, as KK says, type in
"knoppix nocomposite", "knoppix nomodeset" or even "knoppix nodrm", enter,
and report back on your findings.

Just googling radeon 6520G I find nomodeset mentioned a lot; for examples:

Thank you very much for the qualified and detailed explanation. Here is the result of the cheatcode booting: "knoppix nocomposite": no change...no graphics...black screen... knoppix nomodeset: long (ca. 4min) but successful boot...GUI works...everything works.... knoppix nodrm: shorter boot time ---success!... I think about a HD installation on my Laptop and would like to know what repositories Knoppix is accessing? Thanks again for your time and help... K.
