I did an Ubuntu 10.10 Desktop Edition clean install (amd64 version) on a notebook Medion Akoya E1311. With AC adapter everything works fine, but using battery, it hangs after login screen.

I can type login, password too, and I can press login button. But then I can see mouse cursor and lower task bar, not upper, and nothing works. The only thing I can do is login on a terminal with ctrl+alt+F1, this is ok.

Nothing seems alive on Gnome except mouse cursor. The only thing I did after Ubuntu fresh install was donwloading driver for RTL8191SE from Realtek web, because WiFi didn't work, now works fine, with ac adapter of course.

Hardware is a Notebook Medion Akoya E1311

AMD Sempron 210U
1 GB DDR2
ATI RS690M (Radeon X1200 Series)
Western Digital 160GB
wireless RTL8191SEvB
ethernet RTL8101E/RTL8102E
