Is it possible to install ChromiumOS within Ubuntu?
I am NOT looking for dual boot. I want to use as a session like unity or gnome-shell.
Please let me know if anyone has tried it.
If you are using 64bit Ubuntu 12.04 or 12.10 Just download and install lightdm-login-chromeos
Note:it may show some warning messages during installation. Just ignore it.
You can use .xsession to start a session with full screen Chromium, but the entire OS (and user experience when you're logged in) is more than just an X session, and I think would be fairly difficult to re-create. Your best options are installing it as a dual-boot option, or running it in a full-screen virtual machine (the latter is very well documented - I'd check out http://chromeos.hexxeh.net/ for images and instructions).
For more questions, the folks (and sometimes Google employees) in #chromium on irc.freenode.net are very helpful.
