Hi,

>Sometimes these issues can be caused by Flash, does it happen on a
particular web site for example?

I have not noticed something like the system is getting frozen while I am
on a particular website.

freezes) and
post them here.

I am posting the content of the terminal with 'top' command below.

In this particular screenshot I saw that a screencasting software Kazam is
taking lot of CPU %age, but this freezing is happening all the time.

At present I am upgrading the system to Ubuntu 12.10
