Thanks I will have a look

So what is different with ubuntu 6.06, suse 10, knoppix - (and maybe
more), which perform 'normally'  for the hardware?

It is Kubuntu 6.10 which is giving unusual problems. In fact on a few
occasions, unpredictably, 6.10 has not booted properly in the laptop - 
the display
seems not to start sometimes.

I know that the hardware is not good, and not 'made' for linux, but a
lot has been done with linux, and my experience here is that 6.10 is a
small step backwards. I might have to upgrade to 6.06!
