Just installed this, and it works perfectly in windowed mode, but it isn't available in my Ubuntu login screen. Is there anything extra that needs to be done to enable this?
Fix issue #1
Can you run following commands in Terminal:
ls -all /usr/sbin/chromeos
ls -all /usr/share/xsessions/chromeos.desktop
Lightdm won't show login entry if either of two files don't exist or have wrong file permissions.
