No, the number of colormaps isn't the problem (and I don't know any PC hardware with more than one* colormap). If your hardware runs with the mga, glint or ct driver, they you are in luck. These drivers support the option "Overlay" with give you 24 and 8 bit visuals (mga and glint) or 8 and 15 bit (ct). *Some* other hardware (some S3 cards with the right RAMdacs) could support overlays, but most other PC cards don't have the hardware to allow two different visual depths at the same time. (* Actually I would say that anything running XFree86 with overlays is providing one and a half colormaps - one programmable and one fixed.) -- Dr. Andrew C.
