I have a Lenovo Thinkpad Yoga 11e that works perfectly with Fedora 29 running linux kernel 4.19.14-300, but when I upgraded my linux kernel as a part of a normal dnf upgrade and booted into the new kernel the trackpad no longer registers. Touch screen works fine, and I can plug in an external mouse, but it's as if the trackpad is no longer detected.

  1. 4.19.14-300 is now 3rd on my GRUB list of kernels, meaning 1 more upgrade and it will automatically drop that kernel as a boot option. How do I prevent this to buy myself more time to solve the issue?

  2. How would I go about debugging this issue? Usually newer kernels increase hardware support, not the other way around.

Thanks.

For the time being I downgraded my Kernel to kernel-4.17.19-200.fc28.x86_64 and it worked. Need a comprehensive solution to Synaptics Touchpad and Tracking Dot problem with latest Kernels. Tried with Ubuntu too, the same problem arose with 4.18 onwards.

How do you keep kernel 4.17-19-200 from being automatically deleted when a new kernel is installed?

hi there

The Windows Key and type device manager, then press Enter. Under Your PC, double-click Mice and other pointing devices. Locate your touchpad and right-click the icon and select Update Driver Software

hope to help you

Thank you, but it sounds like this is a solution for a PC running Windows. As mentioned in the question I am running Fedora 29. I'm also asking this on ask.fedoraproject.org, which I would hope imply that I'm not running Windows :-)
