I'm new to Ubuntu and have installed 12.10 on a laptop that previously had Windows Vista. I installed 12.10 choosing to use the whole C: drive - so in at the deep end! However, 12.10 runs with a 4 or 5 second lag when it is at its quickest. It also doesn't recognize the USB ports (although there is still power through them). The machine has 1.5 gig RAM.
I have tried reinstalling twice. Any ideas on what I should do? Does 12.04 need less juice to run it? If so, should I try installing 12.04?
Any advice very welcome!
