I don't get a NetworkManager applet icon in my panel when I start the NetworkManager service. I do see some minor moving around of icons when I start the service, so I suspect that the applet is trying to start but failing.
When I try to run nm-applet by hand, first I see this in the terminal from which I started it:
** (nm-applet:17321): WARNING **: Icon nm-no-connection missing: Error opening file: No such file or directory
and then I get a pop-up which says this:
The NetworkManager applet could not find some required resources. It cannot continue.
What does ls /usr/share/icons/hicolor/*/apps/nm-no-connection.* say ?
What icon theme are you using ?
Does gtk-update-icon-cache -f /usr/share/icons/hicolor fix things ?
$ ls /usr/share/icons/hicolor/*/apps/nm-no-connection.*
When I bring up the appearances control panel, the first theme displayed is labeled "Custom", it is the one selected, and there's a warning below it that says, "This theme will not look as intended because the required icon theme 'Clearlooks' is not installed.'" However, when I click on the next theme in the control panel, Clearlooks, it doesn't display an error, so it appears that the Clearlooks theme *is* installed, so I don't know what that warning is about.
I just installed clearlooks-compact-gnome-theme and closed and reopened the control panel, and it still says that Clearlooks is not installed. Is there some other RPM that I should install to fix that problem?
In any case, installing clearlooks-compact-gnome-theme does seem to fix the nm-applet problem.
an icon theme of 'Clearlooks' is somewhat bizarre. All the places where icon theme is stored should default to 'Fedora':
What does gconftool-2 --get /desktop/gnome/interface/icon_theme say ?
It returns "Clearlooks".
I've never changed the icon theme, as far as I know, or for that matter changed the theme at all.
Note that this system has been around for a *long* time, updated incrementally for many years. If I had to guess, I'd guess that it started somewhere around Fedora 6, but that's just a guess. So this is anything but a pristine install :-).
to fix your system, either open the appearance capplet, go to 'Customize', open the Icons tab and select 'Fedora', or
gconftool-2 --type string --set /desktop/gnome/interface/icon_theme Fedora
OK, I can do that, but I'm more interested in how to prevent this from happening to other people when they upgrade to F12...
