I have the same Z13 laptop with the fancy OLED but (until recently) with the Fedora preload instead of Ubuntu. It had a lot of bugs---to the point where I think it could have had a defect (especially after half of the keyboard stopped accepting keypresses even in BIOS and even after full power down and restart; the solution was to plug in the USB charger. Epic WTF). More likely, Lenovo/Mark Pearson were put in a bad place of, "we're releasing for Windows whether you're ready or not!" I suspect the latter because the support forum would often have "we're waiting on the BIOS team", "Intel doesn't have a driver for that webcam", "the haptic thing will get a utility soon", "the temperature issue is known", "the higher resolution timer is unstable", and so on.

The XPS 9370, for me, had ZERO problems. To the point where I wondered often why there aren't more Linux users. It felt like all of my previous Linux pain (especially a life chapter of running Linux on a Chromebook) had gone away.

I looked into a recent XPS but for a variety of reasons (keyboard layout availability in Europe, Michael Dell's political beliefs, wanting to switch away from Ubuntu's snaps and UX, reports of hardware issues on Reddit) I decided to try out "the other" major laptop brand with Linux offerings. Maybe I just got lucky with the last laptop?

Forcing a BIOS reset and installing Windows made enough problems go away that I now just run Fedora Remix as a WSL distribution. Annoyingly, the thing gets hotter than the XPS and hurts my eyes at night. The Z13 with Linux looked so good on paper, now it's more of a paperweight than anything unless I'm traveling.

Also... I wonder to this day if I'm the only Z13 owner who has two separate onboard mic sensitivities (one stereo channel is much more sensitive to nearby sound than the other and has an unusually high DC offset, which simply shouldn't exist on ANY microphone) plus the microphone on my left shows up in Audacity as the right channel (and, of course, vice versa).
