ubuntu 13.10 Screen freeze

Asked by Naveen

I have recently, re-installed fresh ubuntu 13.10 distribution release.
But everything worked fine. until recently i had strange problem of my display screen getting freezed randomly; but no response to either mouse/keyboard.
But i want to point it out; it happens randomly and is not specific ?
Other day, i had music player playing in background, but screen freezed. but my music was still running.
Kindly note, i used multiple monitor setup and same issue of screen freeze also cropped up.

I,am not sure, whether it is bug ?

thanks for the expertise support.

Check your Hard Disk Drive (hardware) for problems - errors.

Open a terminal (CTRL+ALT+T) and apply the following commands one by one.

    sudo apt-get install --no-install-recommends smartmontools
    sudo smartctl -a /dev/sda

Post back here full results.

P.S : First command will ask you for your password. Write it carefully because nothing will appear . It is normal. Then hit Enter.

P.S2: Do not forget to turn the terminal to unlimited scrolling. Edit > Profile Preferences > Scrolling > and tick the "Unlimited" box.
