12.04 no system try

Asked by Dave Murray

I've been having problems with all things related to the system tray since upgrading to 12.4.

Now, I get a no system tray error.

Is there a way to restore it?

Please close all GUIs and save your work.
Please open a terminal: ctrl+alt+t
Enter:
sudo apt-get clean
sudo apt-get update
sudo apt-get upgrade
sudo apt-get -f install
sudo apt-get install ubuntu-desktop
sudo reboot

When there still is an issue reset Unity:
unity --reset

Verify those indicators are installed.
ii indicator-application
ii indicator-appmenu
ii indicator-datetime
ii indicator-messages
ii indicator-power
ii indicator-session
ii indicator-sound

Install dconf-tools, then alt+f2, run dconf-editor.
Go to
desktop.unity.panel
Whitelist the preferred application, logout-in.

Thank you Sam. I did the following which ran uneventfully:

sudo apt-get clean
sudo apt-get update
sudo apt-get upgrade
sudo apt-get -f install
sudo apt-get install ubuntu-desktop
sudo reboot

When I ran unity --reset I got the following (errors) and it stopped:

I had to press the power button on the computer.

I also tried the ii commands. I had to install ii to do them. They all did nothing and I had to ^C out of all of them.

I did not attempt the

I went ahead and installed and used dconf-tools and it did solve all my system tray issues. Thanks so much.

Still a bit curious about the:
(compiz:3538): GConf-CRITICAL **: gconf_client_add_dir: assertion `gconf_valid_key (dirname, NULL)' failed
and
ERROR 2012-05-20 19:46:05 unity.glib-gobject <unknown>:0 g_object_unref: assertion `G_IS_OBJECT (object)' failed

that I got with the unity --reset but the issue that I asked about is solved.

The 'ii' of #1 wasn't a cmd, it indicates if a package is installed and is part of 'dpkg'.
Please try for example:
dpkg -l indicator* | grep ii

The 'unity --reset' output is interesting as it displays bamf.. errors.
Just query the exact wording to find some hints about crypted (at least for a user) messages.
For example bug 979946 shows similar outputs as yours.
Another one there.
