Ubuntu support by default only one X at run levels. I would like to have two Xs: one for Ion3 and for Gnome, in two diffferent run levels. This means that I need to change the source code of Ubuntu somehow and somewhere.
It may be possible to use X11 in one run level and Xorg on another run level without modifying the source code. However, my friend says that this is not possible.
How would you change Ubuntu's source code to enable two Xs in two different run levels?
