Got an Acer AspireOne. Because it’s a netbook, and also I have already another 2 laptops running Ubuntu Desktop and Windows Vista, so I decided to install Ubuntu Netbook 10.10 to this netbook. But after the installation is finished and tried it for a while, I just felt don’t like the interface.
If you also don’t like Ubuntu Netbook, and also don’t want to reinstall Ubuntu again, here is the solution.
I used this command: sudo apt-get install ubuntu-desktop
After the required packages are installed, go to [System->login window], you can set the default desktop environment to Desktop instead of Netbook.
