Kyle,
Thank you, this looks very promising, I had wondered about the
splash screen as this is only thing left that looks like it
takes a lot of colours. I'll experiment with this and see what
happens. In the longer term a restrict_colours option would be
useful in the KDE set up and I suppose in the longer longer term
all display will be 24 bit or better.
Thanks for your help,
matt
