I have a similar issue with my Thinkbook 14 IIL. There's no "_HIDELAN0634" record in the ACPI though, just "ELAN0634".
Applying the patch manually didn't help, but I probably did something wrong in the process (downloaded kernel source, added the missing ID to the driver file, compiled it, applied with insmod = no effect). I can provide some additional info, if it would be useful, and try the ppa:vicamo/ppa-1861610. if someone could explain how to work with it (adding the PPA and running sudo apt-get update didn't install anything new). The laptop runs Kubuntu 20.04, 5.4.0-28. The touchpad worked fine under Windows after installing Lenovo's serial IO driver. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1874374 Title: thinkbook 14-iil elan touchpad does not work To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1874374/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
