I have a Gnome session definition with XMonad as windows manager where I start the gnome-panel explicitly. The session definition looks like this:

[GNOME Session]
Name=GNOME + XMonad

With this setup in one english language Ubuntu 18.10 installation the gnome-panel pops up like this:

I tried all applets available but none is supplying the set of items combined in one applet that I see on another german Ubuntu 18.10 installation starting the Gnome shell (gnome-panel), this is the appet layout that I really want:

enter image description here

The above applet contains all the relevant pieces in on applet.

I think both are called "Indicator Applet Complete" but does anybody know why one version is only showing 2 icons while the other shows all icons?

  • What you call gnome-panel isn't the GNOME panel of old. It's just GNOME shell with some extensions.

  • On MATE Panel it is named indicator-applet-complete if it helps... @muru gnome-panel is still available on 18.10, we can get GNOME FlashBack session based on it.

    @N0rbert : I have installed package indicator-applet-complete and added the "Indicator Applet Complete" but somehow the icons are still only 2 (up-down arrow and mail) The rest of the icons that I'm used to are mssing. Any idea? Dec 1, 2018 at 20:02

    @KonradEisele That is because default GNOME Flashback sessions are started by systemd. See also this file - git.launchpad.net/~ubuntu-gnome-flashback/gnome-flashback/tree/…. So you can try to change gnome-xmonad.desktop to use run-systemd-session... Dec 6, 2018 at 21:25

First of all GNOME Panel is still GNOME Panel, not GNOME Shell.
I have no gnome-shell executables in process list while selected GNOME FlashBack session from GDM. The GNOME Flashback (Metacity) has all indicators in place automatically.

As far I can see on clean minimal 18.10 install - the xmonad package provides session file:

$ dpkg -S ".session" | grep "session$"
gdm3: /usr/share/gnome-session/sessions/gnome-login.session
ubuntu-session: /usr/share/gnome-session/sessions/ubuntu.session
xmonad: /usr/share/gnome-session/sessions/gnome-flashback-xmonad.session # <---

and the /usr/share/gnome-session/sessions/gnome-flashback-xmonad.session contains the following (differ from your only by nautilus-classic):

$ cat /usr/share/gnome-session/sessions/gnome-flashback-xmonad.session
[GNOME Session]
Name=GNOME Flashback (Xmonad)

In GDM3 this session is labeled as GNOME Flashback (Xmonad).

So I installed the components mentioned above with:

sudo apt-get install gnome-panel

Even after installation of full unity-desktop package I can't get all indicators in place automatically.

But I can get them manually:

systemctl --user start indicator-power.service
systemctl --user start indicator-keyboard.service
systemctl --user start indicator-sound.service
systemctl --user start indicator-datetime.service
systemctl --user start indicator-session.service

# and optionally
systemctl --user start indicator-application.service
systemctl --user start indicator-bluetooth.service
systemctl --user start indicator-messages.service
systemctl --user start indicator-printers.service

So I have:

manual load

  • Answer updated - we can get indicators loaded manually.
