[Bug 1874374] Re: thinkbook 14-iil elan touchpad does not work
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 ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

You need 1. patch ACPI to have a legal HID, and 2. a kernel that recognizes this new ID.

@Brian, basically "_HIDELAN0634" is an illegal name according to ACPI specification, so there won't be a overriding fix in kernel because kernel would enforce the names to follow standard.

The touchpad/touchpad driver in question is ELAN0634. A possible fix
would be to add {"ELAN0634", 0} to /include/linux/input/elan-i2c-ids.h
