Somehow the firmware setting for Optimus video got disabled and I regrettably missed the change. Today, while upgrading the firmware to revision A16, I spotted the disabled Optimus video setting.

Update 2015-01-05: I was more or less forced to adopt VT, UTF-8, KMS, and DRM2 when I upgraded my laptop from stable/9 to stable/10 in the time between Christmas of 2014 and New Year of 2015.

A brand new Dell Latitude E6530 found its way to my office to be prepared for use for one of my coworkers. I was surprised to learn that the F2 key doesn’t allow you to enter the BIOS Setup. The computer simply freezes and the screen remains black. Just moments prior the firmware showed in […]
