Second X

[warlord at MIT.EDU (Derek Atkins)]

I had this working a while ago -- I needed a second X because some
applications _only_ ran in 8bpp or 24bpp mode, but my laptop could
only do 8 or 16.  So I ran a second X on vt08 in 8bpp mode.

I had an alias that said:

        (cd ; startx second -- :1 -bpp 8 vt08)

The "second" is passed as an argument into .xinitrc so you can
decide what to do on the second screen.
