You can see my full specs run-downs by clicking on my username. My Acer
Aspire One has similar processor speed (Intel® Atom™ CPU N270 @ 1.60GHz ×
2), but only 1GB of RAM. Trisquel 7 Standard does not run usably with GNOME
or GNOME Fallback. At the moment I have switched desktops to Enlightenment
E17, but I plan to try Trisquel 7 Mini on it soon.
My Fujitsu Lifebook has 2GB of RAM, and an Intel Centrino Duo (Intel®
Core™2 CPU T7200 @ 2.00GHz × 2), and runs Trisquel 7 Standard with the
default GNOME desktop just fine, although if I want to play graphically
demanding games like 0AD, they run better under OpenBox. I've also tested
Mint 17.3 with Cinammon on this laptop, and it runs fine too.
It seems to me like RAM makes a bigger difference than processor speed as to
whether a laptop can support eye-candy. My advice would be to give Standard a
try first. GNOME will be much friendlier to you than LXDE, especially since
you're already familar with it. If you are getting hanging, freezing, and app
crashes (especially in the browser), then try Mini.
