"i8042.nopnp=1 pci=nocrs" does not cure the problem, it only allows the touchpad to be recognized as mouse pointer. In *buntu, under "mouse and touchpads" it is shown as a mouse and no hint of a touchpad. So only right and left click plus cursor movement will work, nothing else.
There are some strange kernel panics in the log file that might be related to this problem, please see attachment. (panics will occur with 5.4, 5.6 and 5.7.7) ** Attachment added: "v15.dmesg" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1881322/+attachment/5389383/+files/v15.dmesg -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1881322 Title: Touchpad not detected in 'Lenovo V15-IIL model 82C5' after installing Ubuntu 20.04 Status in linux package in Ubuntu: Incomplete Bug description: 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.
