I have ubuntu 12.04 on my laptop(Sony Vaio) . I am getting problem
that ubuntu gets hang during working, and I am not able to select
anything and not even teminal opens with (ctrl + alt + t). In
such case I have to shut down my laptop by pressing the power off
button.
What should be the reason behind this?
Is this happens because I am using Sony Vaio (not compatible with Linux) ?
