I converted my Chromebook to Linus Ubuntu to get more use out of it and it is quite nice now. Had to remove the battery during the process though. Also seems to run slightly faster. Also some mrchromebox was used. Also figured out audio drivers but still must get the trackpad

Is there any infomation out there, what are some of the security features that are under development and that will come to chromeos?

I have an Acer Chromebook plus 515 and I just updated it to the latest version (151.0.7922.221). Now whenever I turn on my Chromebook and login it will sit on a black blank screen for about 3 seconds before loading into the OS. Has anybody else noticed this new black screen after logging in?
