Comment 26 for bug 300935

One way to fix this would be for every package requiring rgb.txt to bundle a copy of that file, as several packages already have done (e.g., pixmap (bug #248657), emacs, and a few others). This approach, however, doesn't make a lot of sense, since every package then needs to drag this identical file around, and should there be any changes, everyone of those packages would have to be updated once again.

The only reasonable approach would be, to have *some* single package provide the file, either at /etc/X11/rgb.txt, or at a FHS conform location (in which case all packages requiring it would have to be adapted - but only once!).

It seems, in the past there must have been a similar discussion, and the file was moved(?) to the package "xrgb" https://launchpad.net/ubuntu/+source/xrgb/+publishinghistory . However, this package was deleted in Hardy, moving the file bak(?) to x11-common, and it appears the whole discussion now started once again because the file was removed from xorg.
