Dosemu needs not and should not be run as root, it works fine in X :-)

That is interesting. On the other hand, as you already use xdosemu in

By the way, you can select text in the DOS window with the mouse and
then use the middle mouse button to paste that text elsewhere... :-)

As said, it runs better without being root.
