Knoppix 6.5 on a Laptop with Intel 855 Graphics

[ICPUG]

I install Knoppix as a Poor Man's install dual booting with other OS (Puppy Linux, Windows, ...) off an NTFS partition.

With Knoppix 6.4 DVD and the boot codes as used on the DVD I had no problems with booting up to the desktop.

With Knoppix 6.5 DVD everything goes fine until Compiz turns itself on. Then the screen flashes a lot and the panel disappears, along with bits of background wallpaper! They are still there but hidden. I have managed to get an app (Libre Office writer) open but it is impossible to use. Selected menus flash into existence but disappear again almost instantly.

If I use the boot code no3d at boot up then Knoppix does not turn on Compiz and everything is fine.

This behaviour is exactly the same if I boot up from the DVD rather than the Poor Man's Install.

I don't know the cause of the behaviour change between the two versions - I am just guessing it is something to do with the Intel graphics card as that has been the source of much anguish with many distros recently.

If anyone has any ideas ... , but, if not, then be warned about this potential difficulty if you like Compiz.
