As with any Canary build, though, you'll have to put up with a lot to get this feature early. Aside from going through the process of switching to the Canary update track (we hope you're comfortable with command lines), you'll have to run a decidedly buggy operating system. Be ready for crashes and other hiccups. If you can't bear without a little web surfing before bed, though, it might be worth the sacrifice until night mode reaches stable Chrome OS versions.
