@Anita_Lewis Thank you for the instructions! I just followed them from a Mint Xfce 20.2 stick directly and can confirm functional Wifi (the kernel upgrade did have to be done with a USB-ethernet dongle in my hands), trackpad (had to toggle a setting in “Mouse and Trackpad” for tap-to-click but otherwise A-OK), display, and sound. I have not yet tried anything fancy with the libfprint package for the fingerprint sensor, but so far at least the power button has not become a mini-furnace and I’m not particularly set on having fingerprint login anyway.
Figuring Mint is a decently popular distribution, perhaps a stickied howto/experiences thread/wiki would be helpful for discoverability in the future?
Will add one quality-of-life improvement if anybody else is using xfce: there is a “Brightness step count” accessible from the taskbar battery icon → left click → settings that you can increase to make the keyboard brightness adjustment more fine-grained. The screen is so bright that having the extra resolution at the low end is quite convenient
