I recently updated my ubuntu to 15.04, since then if i open lyx not as root i cannot save files or change documents settings.

Only when i run it with root privileges i can change documents settings and save them, this hasn't been the way before update.

Does anyone know how to do?

Actually you can, but it is quite tricky. When you want to save, just click ALT button and enter save, after that your Lyx menu bar will be active again.
