Xorg cleanup from Archlinux (upstream)
requires some manual intervention before updating (usual update will fail)
Please run that command exactly like it is in one line! The -Rdd option is a must do if not running like this you will probably break your system!!!
sudo pacman -Rdd libdmx libxxf86dga && sudo pacman -Syu
is needed to update system after this all should be back to normal again.
may libdmx is not installed on you system so then do:
sudo pacman -Rdd libxxf86dga && sudo pacman -Syu
After the update it will be safe to also remove the “xorgproto” package. <— if you do not need it (may for pamac-aur-git)
