I have a Lenovo Thinkpad L570 under Ubuntu.

After the upgrade from 17.04 to 17.10, the trackpoint (little red button) and the 3 hardware mouse button don't work anymore.

I test it under Wayland and Xorg, same problem. I don't found any info of this kind problem on the 17.10 version.

  • I have the same problem. Did you manage to fix it? – zunbeltz Nov 3 '17 at 7:50
  • I don't have a solution right now. I hope some help from the community – gatchan Nov 5 '17 at 14:43

This problem is taken by the bug #1731163. https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1731163

I use this page to change the grub parameters and the solution work well: https://wiki.ubuntu.com/Kernel/KernelBootParameters

  • Thanks. This makes the trackpoint work again. But I noticed that now the two-finger scrolling in the trackpad is not working. Do you have this problem? – zunbeltz Nov 12 '17 at 10:30
  • Yes, same problem. So, I use the trackpoint with the middle click button(with the blue dot on it). I hope a definitive solution with the launchpad bug. At this time, the workaround is better than nothing. – gatchan Nov 12 '17 at 18:50
