I am using Ubuntu 12.04LTS on my Toshiba satellite L510 and I have only Ubuntu installed. The system becomes slow and jerky by itself after every 10minutes or so and the remains like that for less than one minute

I had issues with (temporary) hanging/freezes/sluggishness on a (somewhat older) laptop that was (somewhat) resolved by using GNOME Classic (aka GNOME Fallback, & still is gnome3, btw); but my eventual solution was to use gnome2/mate (eventually replacing Ubuntu altogether with the Linux "mint" distro). Perhaps too much cruft from too many upgrades, or maybe the old laptop just couldn't handle the demands of unity/gnome3; I'm sure the situation will improve, but until then, cheers, "mate".
