Have a Lenovo X120e netbook here at work, and wanted to get Ubuntu 10.04 LTS working on it. This turned out to be somewhat less straightforward than I'd hoped, but I managed to get it going. The issue was the RTL8188CE WiFi chip, which apparently does not have out-of-box support in 10.04 LTS.
For anyone else who is trying to make a netbook/notebook with this WiFi chip work with Ubuntu LTS:
1) Go to this page
, and download the "Linux driver for kernel 2.6.24 (and later)".
2) Unpack the tarball.
3) Make sure you have the build-essential package and headers for your kernel installed.
4) Follow the instructions in Section III of the readme file packaged with the driver.
If the world isn't making sense to you, you're either drinking too much or not drinking enough.
