Comment 211 for bug 11334

What do you mean by "separate" ?

Because as far as I've understood the debate, people from Ubuntu seem to say
that this task should be the responsability of X, not of the OS him-self.

Currently, some Apps are working as workarround, but they are not as
efficient as most people expect the clipboard to be. So that's why the bug
have been openned here.

This bug is really old on the Ubuntu launchpad, and I think you might found
even older repports on some other distros. It has only been openned here
recently because I took all those years to figure out what part of the
system was in fault: X.

You can name it a design flaw, but I think it really a major one for the end
users, specially since the all the repports are so old now.
