Bug 4514

there is a growing # of people wanting to utilize their systems more fully by 
sharing 1 PC amoung several LOCAL users simultaniously. by this i mean having 1 
PC with 2 or more keyboards 2 or more mice, and 2 or more monitors--two or more 
USERS active at the same time. X very nearly supports this as is (with seperate 
X instances), the only hurdle is with VT switching, X wants to have only 1 
instance per VT. and only one VT is active at a time.

Several people like Miguel Freitas and Jan "Yenya" Kasprzak have made their own 
patches to allow this in the past. Since these early patches nearly all the 
functionality to allow this has been included in newer kernels and common 
software packages. The only remaining obstacle is with vt switching on X

below is a patch to allow it to work on xorg-x11-6.7.0

There are a great many users would would benefit from this functionality being 
included in newer builds.

As you can see the patch is relatively small and designed to work with command 
line switches which have no effect on users who arent using those command line 
options.

(scroll down on the page, the first part is how to use the original versions of 
the patch, the newer versions of the patch dont require two seperate builds)
