I've added the xorg113 backport maintained by Vi0L0 to pacman.conf, and I have added the maintainers key as per this page
However, when trying to do a pacman -Syu , i end up with this error?
error: key "AFF5D95098BC6FF5" could not be looked up remotely
Got nothing to do with Vi0l0's key. AFF5D95098BC6FF5 is Maxime Gauduin's key and should be in pacman's keyring.
Try updating archlinux-keyring or just add the key yourself before doing pacman -Syu.
