One of the things that i dont like of Gnome Desktop is the keyboard indicator applet that not show country flags like KDE desktop. Searching in San Google i found a solution to fix it, by default gnome support flags but most distributions dont have this feature enabled, to enable it follow this steps:
- Press ALT+F2 and it open the Execute App Dialog. Type gconf-editor and press Enter.
- Now, go to Desktop>Gnome>Peripherals>Keyboard>Indicator and check the box on the right side that says "showFlags". (If you have an older gnome desktop and u dont find it, try: Apps->gswitchit->Applet->showFlags).
- Download the flags of languages that you use(You can download SVG files from Wikipedia searching the country name). Scale it to 64x43 size and move to /usr/share/pixmaps Directory with name XX.png, where XX is the iso country name not the language name, for example i use es.png with cuban flag and my language is Spanish(Spain).
- Now restart your session and you will see the flags in your panel:
