got an S12 and added an other 1GB of RAM.
I installed Ubuntu Jaunty (not the Netbook-Mix)
If i want to display websites in firefox or browse my files in Nautilus there are always lags while scrolling.
It s a small overlay in form of rows thats make a real bad user-experience. It respond so slow.
I deactivated all services and startup-programs which i dont need.
Its even when it just boot up and the cpu is almost in idle.
You can view a similar effekt, when you haven a proper graphicsdriver installed on windows. Then the rendering of pages is laggy and slow in the same way.
