I purchased a Lenovo ThinkBook 14-IML and obviously have Ubuntu installed on it. It's a great machine and runs Ubuntu well, but I just can't use the trackpad. Below are the outputs from various commands I've seen on other posts...

xinput:

If you need outputs from anything else, let me know and I will get them posted.

Thank you

In the lenovo forums, people reported that updating the BIOS to CJCN2508 and building the linux kernel with a patch (which looked like it was going upstream) enabled trackpad on this platform.

  • perhaps you like to get the points as i found it through your link forums.lenovo.com/t5/Ubuntu/… -- make it a proper and nice answer and it will be all yours ;) – db429 Jun 19 at 1:07
  • I'm currently running CJCN27WW, which was released on March 31, 2020. Still no luck, even after applying that Grub text. – user2321023 Jun 24 at 1:12

According to this page your laptop was certified for 18.04, so this seems odd.

First of all you have to make sure your bios-version is (atleast): CJCN2508.

Then there might be a possible solutions:

  • try the oem-kernel; run sudo apt install linux-oem-20.04 in a terminal (Ctrl+Alt+t)

If this does not work:

  • Do you think it's worth posting my dmesg results? – user2321023 Jun 24 at 1:22
  • @user2321023 try to upgrade the bios/uefi to the latest - dkcn29ww released this month and then add the grub option according to the lenovo-forums post linked in my answer – db429 Jun 24 at 12:47
  • according to the Lenovo site, I am up to date on BIOS/UEFI. Where are you seeing that one at? pcsupport.lenovo.com/us/en/products/laptops-and-netbooks/… – user2321023 Jun 25 at 0:48
