This is a follow-up to my previous message today on laptop black screen on booting.

If the display keeps disappearing during booting, you can also hold down Shift & Ctrl to force display of the messages displayed, so you can keep an eye on the booting status.

I've tried setting screen=800x600 and fb800x600 and knoppix-txt and nothing fixes it.

Hi!
I'm just now trying to load Knoppix 3.3 on a Texas Instruments TravelMate 6160 (Pentium 166).

After booting, I've also experienced the same blank screen, with 1 line of flashing (illegible) colour and text at the top. I tried different modes, (and different switches as listed in the cheats file) and finally just pressed Return, to continue loading with the default.

I tried lots of different key combinations then, and found out I could "restore" the correct display by pressing the left-hand Shift and Ctrl keys (press Shift, hold it down, press Ctrl). It works in the opposite sequence too! The display is then perfect for 1 minute, and then disappears again. I've done this multiple times as I type this message!

I'm waiting to see if Knoppix loads and runs: the mouse is working

See if that works for you.
