Public bug reported:
Ubuntu 20.04 is installed in a brand new Lenovo V15-IIL alongside
Windows 10. According to lenovo's support page, the driver for windows
is Synaptics 19.5.10.149_Elan 22.4.18.1. In windows the touchpad works
fine.
This model has two options in BIOS regarding Fn Keys, a "Smart Fn key"
that toogles the Fn key on/off each time you press it and a "Foolproof
Fn Key" that maps the Fn key to Ctrl when you press a combinations of
keys that does not have a Fn assigned. When I enable the "foolproof fn
key" in the BIOS, the Fn + F1...F12 and the sound driver stop working (i
dont have sound, i can't change the volume and the volume icon in the
GUI does not show). Fn+F6 (to enable/disable touchpad) can't enable it.
