My keyboard keys especially "5","R","E" and "F" stops working but after restart it works fine. But it is very difficult to restart laptop while in middle of the work. I have checked in answers relating to my problem in ubuntu forums.
One of the solution which i have got was installing xserver-xorg-input . I did so by sudo apt-get install xserver-xorg-input-all. But still I am facing the problem.
I also want to add thzat the keys which I have mentioned above is working in grub menu and while log in the computer.
I'll be very grateful if you can help me in this regard.
