I have used this line before in my startup and on most of our unix/linux
systems this has defined the colors.
But in five new systems I am using the Elsa Gladiac MX Card it doesn't.
It may be a failure in the graphics driver or by the card.
I got always the greyscale colortable if I choose 24bit for colors.
There was no difference by setting device,decomposed to 0 or 1.
three machines are AMDs two are Intel.
the command device, true_color=24 fixed this problem.
The window command I have already used too.
Many thanks for this hint. This saved me money and time to exchange the
card
to an ATI card.
