ctrl-linux-delete search xorg related packages in repo in Dev Tracker.
for example :
https://dev.getsol.us/source/xorg-server/browse/master/package.yml
the above one is xorg-server and with paches details.
if you need a list of all the packages for X system follow the linuxfromscratch
http://www.linuxfromscratch.org/blfs/view/svn/x/installing.html
and you need system-packages and related *-devel to compile the source code. If you really wanna try then i can share my batch files to you.
Edit : Solus X systems are latest packages you no need download and compile yourself
