First, Xephyr is a better than Xnest and should be used instead of Xephyr so the recommandation is good. Why is Xephyr only a Universe... I don't know maybe it's not mature / stable enough. I personally reported several Xephyr bugs but only one Xnest bug to this date.
As for the symbolic link, Xephyr and Xnest don't use the same command switches (like -screen vs -geometry), so Xephyr cannot replace perfectly Xnest. A "Xnest" symbolic link to Xephyr is therefore not a good idea as some softwares and wrappers won't work as expected, and users won't understand why. Also, all script trying to ps / kill / killall "Xnest" won't succeed as the binary would be "Xephyr". Users should install both for now, and tsclient and other wrappers should be modified to use Xephyr in the future. -- Xnest recommends using a universe package https://launchpad.net/bugs/73990 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
