The xstdcmap utility can be used to selectively define standard colormap properties. It is intended to be run from a user's X startup script to create standard colormap definitions in order to facilitate sharing of scarce colormap resources among clients using PseudoColor visuals. All questions regarding this software should be directed at the Xorg mailing list: https://lists.x.org/mailman/listinfo/xorg The master development code repository can be found at: https://gitlab.freedesktop.org/xorg/app/xstdcmap Please submit bug reports and requests to merge patches there.
