I have some problems or conflicts after using Keyboard layout applet. Before I used it, I have have some accelerators:
Ctrl + Space - changed input language (Russian-English)
Double Ctrl, Double Shift, Double Fn - fixed its functions.
But after install, using, uninstall - I have some problems(may be this problems are in conflict this program with other programs), now:
Ctrl + Space - change tasks
Doublr Ctrl, Double Shift, Double Fn - don't do anything
.... and I can't use virtual keyboard - it doesn't work. But in settings - all flags are enabled.

Now I begin explore file: /usr/share/X11/xkb/symbols/nokia_vndr/rx-51, and now I can change some symbols, for example, on russian layout not exist symbol '=', becouse that button used for russian 'х' and 'ъ'. I change file rx-51, and now I have button with '=', but I don't understand how works combination of symbols...

Sorry, if I have mistakes, but English - is not my
