downgrading my packages has resolved it though.

This may have happened to me as well (but perhaps it's a different bug). How do I diagnose it?

It is not only volume adjustment that is broken, but also screen brightness.

Upon pressing the media keys for screen or volume change, it does eventually work, but with a long delay (perhaps more than 1 minute or more). This seems irrespective of system load.

Similarly, clicking the volume icon sometimes shows the volume bars instantly, sometimes not. It seems scrolling makes it go stuck (and clicking afterwards waits for the volume to change - long delay again, and only then pops up the adjustable volume bars).

I am using Arch Linux. My package versions:

exo-0.12.11-4
garcon-0.6.4-2
thunar-1.8.15-1
thunar-volman-0.9.5-3
tumbler-0.2.8-2
xfce4-appfinder-4.14.0-2
xfce4-panel-4.14.4-1
xfce4-power-manager-1.6.6-1
xfce4-session-4.14.2-2
xfce4-settings-4.14.3-1
xfce4-terminal-0.8.9.2-1
xfconf-4.14.3-1
xfdesktop-4.14.2-2
xfwm4-4.14.2-1
xfwm4-themes-4.10.0-4

I noticed that Thunderbird also hanged for a long time, then showed notifications with new messages. I figured there was something with the notification daemon.

Looking at journalctl I saw org.kde.knotifications: WaitForName: Service was not registered within timeout, then found these lost souls with a solution. There was a conflict of notification services:

$ ls /usr/share/dbus-1/services/ | grep Notif
org.kde.plasma.Notifications.service
org.xfce.xfce4-notifyd.Notifications.service

I had installed KDE's systemsettings for some reason. Sure enough, XFCE was trying to use the KDE service, then failed because it was not running, then fell back on XFCE's.

Uninstalling plasma-workspace and systemsettings did the trick.

It is very frustrating to debug and I think you should still do something for this ticket. I think this could be solved one of two ways:

• by prioritizing XFCE's notification service from the XFCE desktop, if it exists,
• or raising an error message about this issue, not just waiting and then timing out. And a 1-minute timeout is very long.

Thank you for listening! Keep up the good fight.
