Comment 47 for bug 300935

It would be helpful if someone assembled a list of all the packages that are known to be broken by missing rgb.txt

The file is 17K so in terms of disk space the reuse is not essential imo. However, if you prefer to reuse a common file (which is clearly a more _clean_ solution), please create a package for rgb-color-data or such and make them all depend on it. If you choose this approach get the fix into Debian first and let it sync to Ubuntu.

As Timo pointed out above ( https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/300935/comments/14 ); as far as the X server goes, Ubuntu is likely to follow upstream. It's a bad idea to ship data files in the xserver-xorg-core package which is not related to the X server. The only way Ubuntu would be shipping rgb.txt in the core X server package is if upstream puts it back for some reason (you could always file an upstream bug for X to see if this is an option).
