Appending "i8042.nopnp=1 pci=nocrs" to boot parameters worked for the touchpad issue on the Lenovo V14-IIL . Following are the steps I've followed: 1.) Open the file /etc/default/grub for editing, for example by running sudoedit /etc/default/grub 2.) Add to the line beginning GRUB_CMDLINE_LINUX_DEFAULT: "i8042.nopnp=1 pci=nocrs" so that it reads: GRUB_CMDLINE_LINUX_DEFAULT="i8042.nopnp=1 pci=nocrs" ** If other parameters are there between the double quotes, it may be OK to leave them. 3.) Save the file and exit 4.) Run this command to update the GRUB configuration: sudo update-grub 5.) Reboot Other relevant threads for this: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1881322/comments/5 https://askubuntu.com/questions/1206190/elan-touchpad-not-working-on-lenovo-ideapad-with-ubuntu-16-04 https://forums.lenovo.com/t5/Ubuntu/ThinkBook-14-IML-ELAN-TouchPad-Not-Recognized-Ubuntu/m-p/4622518?page=2#5104555 https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1861610/comments/66 https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1861610/comments/96 -- 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/1883010 Title: Lenovo-ThinkBook-14-IIL Touchpad not working Status in linux package in Ubuntu: Confirmed Bug description: The touchpad of this laptop does not seem to be supported.
