I have a dell machine, Synaptics TM3108-002 touchpad, ubuntu 18.04.3 LTS. I faced the same problem after update to kernel 4.15.0-72-generic, touchpad stopped working. I was directed to this link and it kind of solved my problem. I initially wanted to reboot it with kernel 4.15.70-generic but did not know how to do it and the easier option I found was @AaronMa solution.
sudo add-apt-repository ppa:mapengyu/bionic-oem sudo apt-get update sudo apt install linux-image-unsigned-4.15.0-73-generic linux- modules-4.15.0-73-generic linux-modules-extra-4.15.0-73-generic After I followed his solution, touchpad started working again Question: Since I get it from ppa associated with mapengyu, is it a legit ubuntu kernel. I mean it works fine for now but in future will it get normal ubuntu updates as generally my machine gets? So, suppose the ubuntu software updater wants to update it from 4.15.0-73-generic to 4.15.0-75-generic in future, will it accept the updates and in tun apply the update? Question: why does this ppa come from a private user mapengyu and not from ubuntu folks itself? Question: For how long do I need to keep the ppa mapengyu added to my machine. In future can I remove it? Question : How do I reboot my machine with kernel 4.15.0-70-generic? (this is just from my curiosity and not need because @AaronMa suggestion, made my tochpad responsive again) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1854798 Title: Synaptics s3203 touchpad not working after update to kernel 4.15.0-72-generic To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1854798/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
