I have been using an Apple wired keyboard with my 16.04 distro without any problems many months now. Since yesterday, I have unplugged this keyboard and plugged in my Razer keyboard. When I plugged the Apple keyboard back in, some keys stopped working (b and p for example).
I have tried:
sudo dpkg-reconfigure keyboard-configuration
After reboot, still no luck.
I have also tried setting Num lock on or off using the other keyboard. Still no luck.
Any solutions to bring it back to the previous working state before I plugged in the Razer keyboard will be greatly appreciated.
Thanks a lot in advance for your time.
Alex
