Samsung RV510 Ubuntu graphics slow?

view story

http://askubuntu.com – I'm fairly new so I'll try to be clear. I have a Samsung RV510 laptop (Dual core, 4GB Ram, Chipset graphics etc) In the past I have used Windows 7 and 8 on the machine and 3D/2D graphics have run fluid and fast. Since putting Ubuntu 12.10 on the machine, opening up the console, watching youtube vids or moving windows around just seems to be very laggy or jittery. I then installed 12.04 to test if that was the same, which it was. I don't have any additional graphics cards etc, just stock hardware but as I said, Windows was fast and fluid with no issues at all. I much prefer to be using Ubuntu, (HowTos)
