Mmmm... Never needed to do that!
You'll need to have some non-root user with the appropriate groups set
(video?) to run the startx... su "non-root" needed?
Or might you just need the access to the X11 display screen enabling to
allow other processes?
For whichever shell has run the startx, issue the command:
xhost +si:localuser:other_user_for_access
to allow "other_user_for_access" to do things to the display screen.
Take a look at what the various login display managers do?
And trying to use ssh is going to be awfully confusing for whether
things are getting X-forwarded back over ssh!...
Good luck?!
Others??

Great fun but also...
Is that better than rooting a cheapie graphics pad for similarly swish
fun for similar price and effort?
:-)
