Finally I found the perfect distribution for my Asus EeePC 1101HAB. Ubuntu 11.04 was performing kind of ok there, though a tad bit slow. But when I upgraded to 11.10, the hell broke loose. First, my NetBook won't boot to gnome 3, then I downgraded it to gnome 2, it would boot to text version where manually I had to start lightdm. Unity made it very slow and I started thinking of buying a new laptop. However, yesterday when I installed Ubuntu 11.10, to give a last try to Ubuntu 10.04LTS, things started working like a charm. Lucid is much faster and lighter desktop than later versions. I'll post the CPU and ram usage details in a day or two.
