I also had this problem. Touchpad stopped working after installation of Kernal 4.15.0-72, working fine after reverting to Kernal 4.15.0-70. Kernal intstalled using linux mint update manager, and removed again with update manager.
Although I occasionally use the terminal, I am an ex Windows user and find the Gui packages easier to use. Laptop is a Dell Inspiron 15 3000 series - running Linux Mint 18.3 and Windows 10 in dual boot configuration. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1854896 Title: Synaptics TM3336-004 Touchpad Stopped working after update to the latest kernel 4.15.0-72 generic To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1854896/+subscriptions -- ubuntu-bugs mailing list email@example.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
