I have a Dell precision laptop from 5 years ago. Every single piece of hardware is supported in Linux, including the smart card reader and the dual Nvidia Quadro and Intel graphics. With Ubuntu 18.04 hibernation, which was enabled, would sometimes cause graphic glitches when resuming. Fixing them required a reboot. From 18.10 onward the issue has been resolved completely. Perhaps this is because of special attention from Dell and Canonical? Linux is listed as full supported by Dell for this laptop. I did ensure I had a swap partition larger than my available RAM.
