I've never heard of this happening with a Chromebook. There are two ways to run Linux on these boxes, either in a chroot (Crouton) or to wipe the machine and install Linux.
For machines that just need a Linux app or two, I use Crouton. Crouton has a sweet Chrome plugin that pushes X Window frames to a browser tab. So, you can install a Linux desktop manager, and push the whole GUI desktop inside a tab. Or, you can install without a desktop manager at all, and just push the selected app inside a tab. This works remarkably well. Need Audacity on a Chromebook? No problem. Need Dropbox client? Again, no problem.
What's really great about this is you actually WANT Chrome to get all of its automatic updates, especially of the drivers and security. That really is a huge selling point for Chromebooks. Set it and forget it.
For machines that will really be a Linux desktop, such as my dev box, I did open up the laptop, replace the tiny SSD, and remove the silly little sticker that was preventing me from writing my own boot loader image. 10 mins., tops.
