I've run into an unusual problem. I have two different versions of xorg-server in two different repositories in my computer: extra repo - 1.19 and xorg116 repo (built from source) - 1.16. How do I uninstall the package from extra repository while keeping another version in xorg116? I would've installed a different version from /var/cache/pacman/pkg but I've cleared the folder.
P.S.: I need to downgrade it so I can install AMD drivers. P.P.S.: here's some output from "pacman -Si xorg-server":

This sounds like you are chasing the wrong problem... Why do you need to downgrade to use the drivers? The AMD "official" binary drivers are being phased out and replaced with the open source ones that AMD contributes to, can't you just use the radeon drivers? – acejavelin – 2017-03-18T14:40:49.847
The newest open source ones do not support Xorg 1.19 or newer. – airbournenation – 2017-03-19T08:11:08.020
