We have a motif application using XAllocCollorCells( .. ) to allocate a color map. The application gives an error "could not allocate writable color map" when it attempts to connect to the X server running on my Fedora Core 3 linux system. Other motif applications like xclock, xterm work fine. I have googled and have discovered that the X server used in fedora core 3 is Xorg and that iits default color map is not writable etc. One suggestion was to configure Xorg to use Pseudocolor as default color map.

How do I get around this problem? I am not clear about configuring Xorg for pseudocolor. Your help is greatly appreciated.
