Did you provide a model number for that laptop already? Sorry, but I

I'm sure the specs you need are out there, you just have to know how to dig them up. It's an Inspiron 1000, rev. A03, serial #18850470553. I couldn't find a date of manufacture on the case. I also checked what Windows thought the video chip was: SiS M650, with resolution 1024x768 (max). Linux says it's an SiS SIS 650, and has no entry among the SIS chips for M650, so I assume that SIS650 and M650 are the same. There are a whole lot of chip-specific parameters that can be set, too; possibly Windows knows how to set them and Linux doesn't, but I don't know how to get Windows to reveal its settings.
Also, I wouldn't drive that display too long with the effect you're describing. It's more likely they're due to an inherent incompatibility between the display and the signals being sent to it than any kind of harmonic interference. This is especially true if it doesn't go away when you change modes.
I'd attach an external (analog) VGA monitor until we can determine you've defined the graphics adapter correctly. Fiddling around with the display settings doesn't do much good if you're not using the right driver and/or settings for the graphics chip, itself.
I hope this information will help you diagnose what's going on. Paul
