Just installed a stock Ubuntu 8.10 on my EeePC 701 and the result is a mixed bag.
On the plus side, Ubuntu automatically detected and configured the correct resolution for the EeePC. That part was fairly simple and straightforward.
On the downside? Well, there are several:
The disappointment stems from the expectations that 8.10 was written for the EeePC. At a minimum, I would have expected something better with the screen real estate layout and the onboard Wifi. While there are automated scripts to fix all this, they're all written for earlier versions of Ubuntu.
I know there's also Ubuntu-eee but I've been avoiding it because it's not an official port. But the way things are, I think I just might try it next.
