Linux Kernel Finally Nearing Support For The Apple Magic Trackpad 2, Thanks To a Google Employee (phoronix.com)
Michael Larabel, writing for Phoronix: Apple announced the Magic Trackpad 2 almost three years ago to the day while the mainline Linux kernel will finally be supporting this multi-touch device soon. The Magic Trackpad 2 is a wired/wireless touchpad with haptic feedback support and is a much larger touchpad compared to the original Magic Trackpad. There unfortunately hasn't been any mainline Linux kernel support for the Magic Trackpad 2, but some out-of-tree options. [...] However, as seen by this bug report there have been plenty of people since 2015 interested in using the Magic Trackpad 2 on Linux. Fortunately, Sean O'Brien of Google's Chrome OS team has been working on Magic Trackpad 2 support with a focus on getting it mainlined. The patch, which was also reviewed by other Google/ChromeOS developers, is now up to its third and perhaps final revision.
I always used my Magic Trackpad 2 with my desktop. Never used it with a MacBook. When I DO plug in my MacBook at my desk, I also use my preferred keyboard. Why use an external trackpad and not use whatever keyboard you want, Bluetooth or USB? I'd think that if one added another trackpad, they'd also add their preferred keyboard.
