I'm trying to change from the default colormap in X to XA_RGB_BEST_MAP with no success. I'm following code I found in O. Jones book in the color section. I have pinpointed the problem to the function XGetStandardColormap() which always returns a 0 (failure). Might there be some problem with my version of X? If so, what other options do I have? Thanks.

I have pinpointed the problem to the function XGetStandardColormap() which always returns a 0 (failure). You have to run some client that creates a standard colormap. In R4, try "xstdcmap -best".

The most probable cause, in my estimation, is that nobody has created an RGB_BEST_MAP on the root in question. If you think someone has, you might check with xprop and see. (If this is not what's wrong, I haven't a clue.) der Mouse old: mcgill-vision!mouse new: mouse@larry.mcrcim.mcgill.edu
