The X11 connection broke (error 1)

The following message began to appear after a recent system update.

msm_notifier[nnnn]: The X11 connection broke (error 1). Did the X11 server die?

It occurs after each logout from an Xfce desktop session and I observe it on my desktop PC as well as my HP laptop which are both running ManjaroLinux 26.1.0 built from official Manjaro Xfce image.

And if you run it manually, does it say it is already running?

This is the Manjaro Settings Manager Notifier - a notification module for kernels.

You can safely remove it from ~/.config/autostart

Then remove the package

pamac remove manjaro-settings-manager-notifier

Thanks for the response. I chose to un-check MSM Notifier in Application Autostart which resolves the issue starting with the next login/logoff cycle. I did not remove manjaro-settings-manager-notifier just in case a future update resolves the issue. A potential alternative solution, for those who would prefer to keep MSM Notifier selected in Application Autostart, would be to include:

pkill --uid <username> msm_notifier

in a script that is run before logout from the desktop session.

BTW, msm_notifier.desktop only exists in /etc/xdg/autostart on my system.
