No surprises here. Just like the lockdown on iPhone screen and part replacements, Macbooks suffer from the same Apple’s anti-repair and anti-consumer bullshit. Battery glued, ssd soldered in and can’t even swap parts with other official parts. 6000$ laptop and you don’t even own it.
The L14 Gen1 I have must be an exception then. The fingerprint reader isn’t compatible at all (I feel kinda taken for a ride there since it’s seemingly the only Synaptics reader without Linux compatibility) and both Bluetooth and USB are very buggy. I haven’t used it with Windows, so the latter two may also be down to crappy firmware. Either way I’m rather disappointed for the price tag and probably not buying Lenovo again any time soon.
Unfortunately, the Synaptic FP reader in yours might unironically be an anomaly, as the one in my L470 was supported even during Ubuntu 16.04 era. It may be possible that since the *80 generation of ThinkPads, the E and L series closed the gap on mediocrity, unlike the T/X/P series. Lenovo does maintain though a Linux compatibility chart for ThinkPads.
T14 Gen 2 (AMD) has Linux compatibility issues with the touchpad of all things.
