This is why OpenBSD is the superior desktop operating system. Fixed months ago. :)
I'm sure most people here don't even know it's the only OS in the world allowing you run Xorg as an unprivileged user.
Just like Linux taught me to appreciate FreeBSD, FreeBSD taught me to appreciate OpenBSD. OpenBSD -- the world's simplest and most secure Unix-like OS. Creator of the world's most used SSH implementation OpenSSH, the world's most elegant firewall PF, the world's most elegant mail server OpenSMTPD, and the OpenSSL rewrite LibreSSL. OpenBSD -- the cleanest kernel, the cleanest userland and the cleanest configuration syntax.
FreeBSD -- growing overly complex [1], lagging on security [2], packing itself with unnecessary, experimental technologies, and representing itself with a satanic mascot and a shiny, dildo-looking logo.

Maybe the first, but these articles claim Fedora can do it too, although currently you need to edit a config file, and it only works if you invoke startx(1), not when logging in from gdm.

"X is now rootless with the help of systemd-logind, this also means that it must be launched from the same virtual terminal as was used to log in, redirecting stderr also breaks rootless login. […]"

This is obviously not a feature of archlinux itself, but an upstream x.org feature.
Attempting to talk about "Linux", as if some single operating system - lack of pluralism between commenters to handle the differences notwithstanding - is a problem with this thread.
