I'm using Ubuntu 11.04 with a Packard Bell Dot S netbook - Atom N450 processor, Intel GMA3150 chipset, 1gb RAM. It's 64 bit, but I had tried 32 bit too and the performance difference was unnoticeable by me, with roughly a third of the RAM being used by both.
Currently I'm using the Classic/ no effects option but with Metacity's compositing, a left-side Docky and the default Ambiance theme, approximating Unity. It's noticeably much smoother and I'm wondering if any tweaks can be made, e.g making a xorg.conf, to make Unity run better - I had Ubuntu on my laptop when 9.04 was out and I dimly remember some lines we had to add to xorg.conf to make Compiz smooth.
I may have misremembered this but wasn't Unity evolved from the Ubuntu Netbook Remix desktop? Odd that it struggles on this netbook then. (Is Compiz fixed for 11.10?)
Thanks.
