I have a new Lenovo t520 with 8gb memory and a i7 cpu. It's the first time I 'really' install Ubuntu on a pc. I have about six months of experience with Ubuntu as a guest OS on Windows in a VM.
Now what is really annoying me is how slow the visuals are on my laptop. Mostly noticeable when I have to resize or move a window. Also when scrolling text in vim/browsers it's not really as smooth as I would like it.
I read that Lenovo is using Optimus drivers for their new laptops and that these aren't supported. So I was wondering could using the integrated Intel gpu be the problem?
The CPU I have is the Core™ i7-2620M (2.70GHz, 4MB L3, 1333MHz FSB). I have tried to enable desktop effects but that didn't work.
