I've stuck with Linux Mint MATE ("Gnome 2") _because_ I know it works and I don't want to pull the multi-arm bandit to see what else breaks on other distros or window managers (or how bad the UI is). It works wonderfully on my Lenovo Yoga 730 (15" touchscreen) and Thinkpad P1 Gen 5 (no touchscreen). Videos playing in Firefox no longer prevent screen lock, but easily fixed by an applet toggle. I had issues with the P1 Gen 3 touchpad tap timing after awakening but .... ¯\_(ツ)_/¯
