Comment 44 for bug 300935

Sorry I wrong. I ran those commands in a ssh terminal which was logged into a machine that has been upgraded since gutsy. I checked again on my cleanly installed jaunty box and there I don't have the file anywhere in /usr and not under /etc either, despite having x11-common and gcolor2 installed. If I open gcolor2 the colors and indeed missing on this machine just as you suggested.

I also grepped the upstream xserver git tree and found this:
