I recently changed unity for classic Desktop. So, i noticed that the volume control dissappeared.
So i read everywhere that the only thing to do is add the Inidicator Applet in the panel. But i dont have that option in my applet list.
The indicator applet has not been ported to GNOME 3 and GTK3 yet. This is required for it to work in Ubuntu 11.10. There is currenly a bug tracking it.
Indicator-applet is now available for testing in a PPA.
As with all PPAs - these are for testing purposes. Have a stable backup or use ppa-purge to remove PPAs that could make your system unstable.
Now install the applet you want to add to the panel:
1) The whole indicator applet:
2) Unity Global Menu type applet:
3) Session applet:
4) Standard applet:
To add to the panel:
Win+Alt+Right click the panel if using Gnome-Classic or Alt+Right click the panel if using Gnome-Classic (No Effects)
Choose Add To Panel and add the following indicator
You can tidy up by removing the old notification area.
The end-result could look like this:
N.B. I've also added RadioTray, StackApplet and Skype...
