A recent system upgrade in 14.04 disabled the Ctrl key in my Asus K55VM-SX086D Laptop. Initially there was some problem where the screen used to go blank when pressing the ctrl key when I was using 13.10, but somehow after upgrade to 14.04 it was working fine. However after the recent upgrade its not working again.
I have checked the default US keyboard layout and it does not seem to recognize the two Ctrl key. Please help.
Do let me know steps that I can follow to resolve this issue. Thanks.

. It should tell you every time you input a key. If it doesn't respond to the key, it's a problem with the keyboard. If it does respond with something like a keycode of 37 (you'll need to look at the output of the terminal for this), comment back and I'll look into it further. :)
