I somehow had them working before in 11.10 but I don't really remember what did I do back then other than activating "load Gnome components on start up" in the XFCE's settings manager.

I've tried the same in 12.04 but doesn't seem to do anything, I specifically ask for the Volume notifications as other notifications used notify-osd or xfce4-notifyd but the volume one was Gnome's (I found that later) As far as I know it uses notification-daemonbut installing it instead of the other two doesn't give me the correct notifications.

I'm using XFCE 4.10

This is what I get from running gnome-settings-daemon in the Terminal.

The short answer is: No, You cannot use it in XFCE.

You correctly said, Gnome-Shell's volume notification is it's own and it uses notification-daemon. The notification-daemon is a program used to display the pop-up notification. You can use "notification-daemon" is a generic name for any daemon providing notification. For XFCE it is xfce4-notifyd.

Gnome-Shell uses gnome-shell-hotplug-sniffer program which resides in /usr/lib/gnome-shell/ to give the Volume notification. As this is a very internal component of gnome-shell (it runs automatically with gnome-shell) you cannot use it without installing gnome-shell or using it.

To see that this indeed is responsible for Volume notification, temporarily disable it by renaming it to gnome-shell-hotplug-sniffer.bak file

sudo mv /usr/lib/gnome-shell/gnome-shell-hotplug-sniffer /usr/lib/gnome-shell/gnome-shell-hotplug-sniffer.back

Then restart gnome-shell with the command gnome-shell --replace from Alt+F2 graphical command box. Try mounting a drive and you'll see there is no notification for mounted drive.

To restore back the file, use this command to rename it to original name

sudo mv /usr/lib/gnome-shell/gnome-shell-hotplug-sniffer.bak /usr/lib/gnome-shell/gnome-shell-hotplug-sniffer

Run gnome-settings-daemon in the background. It handles special keys, keyboard layouts, and the like.


Should've tested that before posting.

You can get gnome-settings-daemon running with:

$ killall xfsettingsd && gnome-settings-daemon

Note that this will set your GTK theme to the default old-school GNOME2 look. But you will have your GNOME-style volume pop-ups.

I get errors, it shuts down when running, I'll edit the question. – Uri Herrera Oct 2 '12 at 1:09
Nope, still get the regular notifications but It does default to the Raleigh theme. – Uri Herrera Oct 3 '12 at 1:47
Bummer. I actually get the little GNOME keyboard / volume popups on my setup. – Eric Oct 4 '12 at 11:20
gnome-settings-daemon runs in Unity also, but we do not get that popup in Unity. So, it definitely isn't gnome-settings-daemon – Anwar Shah Oct 7 '12 at 17:18
