Comment 27 for bug 188764

This should not be done in ubiquity; the less package-specific work done there the better. It's perfectly possible for usplash to look at DISPLAY in its own postinst when writing out its default usplash.conf, rather than the baroque idea of having it write out usplash.conf and then have ubiquity go round and fiddle with it immediately afterwards.

And yes, anything based on interrogating the current X display will lose on the alternate install CD, on ubiquity's noninteractive frontend, and probably in other cases. The only way to fix *that* is to probe at boot time, which is definitely too risky for 8.04. I'll leave this bug open for that work to be done later.
