The `killall` command doesn't come shipped in all distributions (Void Linux as an example), on the other hand `pkill` does. Unsure what the exact intention on each call is but the `-9` signal can be replaced with `-x` if the intention is not to end all instances. Also note that I left `pkill -x Xorg` without the `-9` signal because for some reason it won't function as expected and end up halting the system (at least on Void Linux).
