[This review was collected as part of a promotion.] I've been using this laptop for a couple of weeks now, with Linux Mint 20.3 Cinnamon. The only hiccups I've had is with some suspend-related issues (which were resolved with a BIOS setting change) and with the display getting confused sometimes with docking and undocking with 2 monitors attached to the dock (which can usually be resolved by unplugging the dock and giving it a 30 seconds to figure out what's going on before plugging it back in).
Beyond that, the only things I'd like are one or two more USB-A ports on the laptop itself (as opposed to the doc), and the ability to expand the RAM.
