1. First of all please remove all other software that tries to set keyboard layout: bt-hid-scripts modified Xorg evdev driver (if installed) modified layouts whatever else you have installed related to bluetooth. 2. Reinstall extkbd (and extmou if installed) in terminal as root: apt-get install --reinstall extkbd (apt-get install --reinstall extmou) 3. Reboot your n900 4. After the reboot re-pair your keyboard 5. Go to settings->external keyboard. You should have your bluetooth keyboard listed. Set first language to USA(variant none), second to your preference(Romanian?) and try with different settings for keyboard layout (for example MacBook/MacBook pro) to see if it will work. As your keyboard uses non-standard layout and the model is not supported it could take a while until you find the correct layout. After EVERY settings change you must push Save button so your changes to take effect.
