Indicator Applet

Indicator panel locked

Asked by Martin Baumann

Running Ubuntu Lucid Netbook on a Samsung NC10, fresh install from Karmic. Unable to modify indicator panel or add other panels. Right-click on panel does not provide "preferences" dialog, " Remove from panel", "Move" and "Lock panel" (which is clicked) are greyed out. Removed evolution from "usr/share/indicators/applications", but envelope remains on the panel.

Hey Martin :)

If you want to completely remove the envelope, you have to open System → Administration → Synaptic Package Manager, search for »indicator-messages« and remove it.

You can also do it by copying and pasting this into a terminal: »sudo apt-get remove indicator-messages«

As for the panel, it may be locked down (preventing changes). You can edit that setting by opening up a program input with Alt+F2, then type »gconf-editor«.
In there, go to /apps/panel/global/. The key »locked_down« will likely be set to true – just change it to false.

You can also do it by copying and pasting this into a terminal: »gconftool-2 --set /apps/panel/global/locked_down --type bool false«

Thanks J-C. The envelope is gone.
The panel lock-down is more interesting: the key "locked_down" in gconf/apps/panel/global was actually set to false, ie. not ticked. However, all the /panel/applets/ applet_0 through -7 are all locked, with a note "this key is not writeable". What do you think?

I think I found a solution for you. The problem seems to be specific to the Netbook Edition:

I hope that solves it for you, more info in the thread :)

You did, thanks very much! I have set the default to use a gnome interface, which suits me fine, and that removes the lock on the panels. They are now the same as I use on my desktop machine. I have to agree with some of the other contributors, locking that down is an unfortunate decision.
Again, my thanks for your help.
