After upgrading gnome shell or others upgrades, suddenly all the icons on my gnome shell’s top panel totally went missing. There are no network or volume or network icons but they still work from the gnome panel. I can hover over where I know the volume one should be and it works! I tried new icon packs and themes also end up nothing.
Anyone have some tips? Clock and date are working, just wondering about the icons missing. So, to fix it. Just reinstall some of the gnome shell theme option.
You may try below command: (as for me “gnome-icon-theme-symbolic” is enough)
$ yum reinstall gnome-applets-data
$ yum reinstall gnome-icon-theme
$ yum reinstall gnome-icon-theme-symbolic
$ yum reinstall gnome-panel
$ yum reinstall gnome-settings-daemon
$ yum reinstall gnome-wise-icon-theme
