As the title says, the built in keyboard on my Sony VAIO SVE1712V1EB does not respond after booting. Neither it does in GRUB.
However when I suspend the computer / restart the X-Server, the keyboard is recognized and works fine.
I am using Ubuntu 14.04 and I have set the bootmode of UEFI to legacy.
What do I have to do to get the Keyboard working immediately after booting?
