Just installed ubuntu on my old acer aspire 5515 laptop for testdriving my first shackel free OS.

sofar so good....looks promising, but running really reaally sluggish compared to windows, its a fresh install and assuming i need drivers.

I go to system settings>hardware>addition driver..... it does a search then says "no proprietary drivers are in use on this system"

any ideas on where to go from here?

On windows I would just get on the net and DL my drivers, is it the same process here or....??

thanks
