Linux on the Thinkpad X1 Yoga 4th gen

Laptop ordered May 27, arrived May 30. Lenovo has improved a bit, although in all fairness, this was pre-configured. I wanted it cheap, so only 8GB (soldered :-() memory and 256GB NVME SSD. It seems their credit card issues are passed now. This has a 10th gen intel, but I decided for the i5-10210U, since it has the same cores and uses less juice. Runs at 1.60GHz (4200 bogomips), but in so many gen's intel hasn't really been able to speed up their processors. Or is it the compiler now?

Installed Kubuntu 20.04, I turned off secure boot, not sure if this was needed. The drive was on /dev/nvme0p1, which was new to me. 4 partitions were set aside for windows/UEFI, so I wiped windows, and kept the other 3 little ones, in case it ever has to go back (to windows). In past history this has never happened.
This is also the first (or one of very few) times that /home is on /, i usually split them. But this is only a 256GB drive. Current speed was about 1000 MB/s (hdparm)
Comments/Issues

design is ok, but I do miss a charging (usb-c here) port on the right.
not sure yet, but the wifi crapped out after some minutes of heavy use, disable/enable did the trick. will have to come back on this if this remains an issue.
in terms of using the touch screen, this is not like a chromebook, a single finger cannot scroll the page, and for fine work you really need the styles. those fingers are just too fuzzy.
no fingerprint reader
no screenrotation if you use the tablet mode. manually works.
