Hi,
I have been "playing" with Linux and/or Chrome OS on my Aspire One 722.
So far I haven't found a Chrome OS or CR OS linux that will handle the Radeon video card.
I have found that Ubuntu distributions are handling the card. I have successfully installed both Zorin OS v9 (Core and Lite) as well as Lubuntu. I haven't had a chance to install Pepermint 5 yet but I have the copy.
All of these are suggested as excellent turnkey installs for netbooks. They come in 32 and 64 bit versions.
Since I was trying to turn my Aspire into a Chromebook look alike it is possible that either Pepermint 5 or Lubuntu will do the trick. Zorin OS is specifically designed to look like various Windows interfaces (the higher end paid version also includes a Mac/OS10 look alike and Windows 2000).
They all appear to install without tweaking.
Enjoy.
Tom
