Thank you for that pointer. I had to adjust this command:
cat /sys/bus/iio/devices/iio:device0{name,label,in_accel_{x,y,z}_raw}
to add a slash after deviceN:
cat /sys/bus/iio/devices/iio:device0/{name,label,in_accel_{x,y,z}_raw}
Also, on my system device0 is cros-ec-lid-angle while device1 is cros-ec-accel device-display and device2 is cros-ec-accel device-base. I’m not sure if that matters. I guess I can boot back into the fedora liveusb and see what it shows. I will try that at some point.
Edit to add - user error. Details here: What are the Linux system requirements for tablet mode? - #66 by lbkNhubert
