Hi Jonathen,
Thanks again for the prompt response.

I've heard about that but in this case it couldn't happen in 4MB.
1280 * 1024 * 24 / 8 / 1024 / 1024
3.75
1280 * 1024 * 32 / 8 / 1024 / 1024
5.00
I couldn't run 24bpp until a later XFree86 supported it; 32bpp wasn't
possible.

Thanks, but I don't think I could stand that :-)
I'll switch to 16bpp for vncviewer compatibility.
Thanks for confirming that this was the problem.
Ralph.
