It looks like you don't have the associated xorg package installed with it. https://launchpad.net/ubuntu/+source/xserver-xorg-input-libinput
You should check your Xorg log to see if libinput is active. Given this initial issue is resolved (touchpad stopped working) I'm going to close this kernel task. If there ends up still being another bug related to the performance you should open a separate bug relative to the libinput package. Feel free to subscribe Kai Heng Feng and myself to them (although I'll be on vacation so I may not respond for a while). ** Changed in: linux (Ubuntu) Status: Confirmed => Invalid -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1737639 Title: Touchpad stopped working in Dell XPS13 Status in linux package in Ubuntu: Invalid Bug description: I have a Dell XPS 13 9343 Recently, the touchpad stopped working. The touchpad works under the BIOS, so I believe that it is not a hardware issue, but a Linux kernel bug. The touchpad does not show up in cat /proc/bus/input/devices For the touchpad, the Vendor name is COMPAL and the Vendor Part Number is PK09000FS0L The problem is currently visible in 4.13.0-16-generic though this kernel originally worked, I believe, and 4.13.0-17 failed. I continued to use 16 for a while, but after the upgrade to 4.13.0-19, 4.13.0-16 stopped working as well.
