The issue seems to be that "Accounts Service".  When I look at what's running on my machine with the keyword "account" I see this:

# ps aux | grep -i account
root         666  0.0  0.0 237396   236 ?        Ssl  Feb06   0:00 /usr/lib/accounts-daemon

# pacman -Qo /usr/lib/accounts-daemon
/usr/lib/accounts-daemon is owned by accountsservice 22.08.8-2

Perhaps that "accountsservice" package somehow got uninstalled on your machine?  A quick search turned up this page, which would seem to also suggest that: https://dev.to/nabbisen/fix-lightdm-error-the-name-org-freedesktop-accounts-was-not-provided-by-any-service-files-512b

Thanks David,

Had already found the accountsservice posts -- unfortunately that isn't the issue here. (installed it, rebooted, checked with linux and linux-LTS, no difference -- uninstalled it)

There is some distinct permission or auth change in the package updates from the last 3-4 days that is preventing an xorg connection resulting in "Connection Refused". I captured the full startx output in case that helps:

$ startx

It appears I'm not the only one. Soon after posting to the AUR project for the nvidia-390xx drivers, another confirmed x broke for him as well. See latest comments at:

https://aur.archlinux.org/pkgbase/nvidia-390xx-utils

So it has to be some change that the nvidia-390xx driver isn't playing nice with. Like I said earlier, my Intel graphic box is happy as a clam.

Also, xorg itself is happy with the nvidia-390xx driver, loads it fine, no errors in Xorg.0.log and X seems to fully start before being shutdown by the "Connection Refused" error.

Nothing else has changed on this box. It's a server doing mail, web, dns, dhcpd4, etc... that just sits there doing its thing. Simple OLD AMD 8-core with 32G and 4T in 4 RAID1 partitions. That how I know NOTHING changed on the box -- other than pacman updates on 2/7 and then I rebuilt the nvidia-390xx driver packages (no difference, same issue)

The server aspect also makes it a bit difficult to take offline for rollback and testing that takes the server down. (I have another Arch server doing backup dns and dhcpd for the local LAN and a backup mail host at the office, but even so, I'm a bit reluctant to purposefully take it off line unless the electric company does it for me...)

So I'm a bit stumped on where to dig to find whatever changed? I mean do I strace the startx call -- would that be useful?
