Title: Touchpad doesn't work out-of-the-box in Ubuntu 18.04.1 with ThinkPad X1 carbon Status in linux package in Ubuntu: Confirmed Bug description: The touchpad doesn't work after installing Ubuntu 18.04.1 on a new Lenovo ThinkPad X1 Carbon laptop. I see log messages like these repeatedly: ``` Sep 27 15:41:17 jik-x1 kernel: [ 3.824013] psmouse serio2: Failed to reset mouse on synaptics-pt/serio0 Sep 27 15:41:17 jik-x1 kernel: [ 9.388812] psmouse serio2: Failed to enable mouse on synaptics-pt/serio0 Sep 27 15:41:30 jik-x1 kernel: [ 33.124787] psmouse serio1: TouchPad at isa0060/serio1/input0 lost sync at byte 1 Sep 27 15:41:30 jik-x1 kernel: [ 33.126159] psmouse serio1: TouchPad at isa0060/serio1/input0 lost sync at byte 1 Sep 27 15:41:30 jik-x1 kernel: [ 33.127437] psmouse serio1: TouchPad at isa0060/serio1/input0 lost sync at byte 1 Sep 27 15:41:30 jik-x1 kernel: [ 33.132428] psmouse serio1: TouchPad at isa0060/serio1/input0 lost sync at byte 1 Sep 27 15:41:30 jik-x1 kernel: [ 33.133608] psmouse serio1: TouchPad at isa0060/serio1/input0 lost sync at byte 1 Sep 27 15:41:30 jik-x1 kernel: [ 33.133613] psmouse serio1: issuing reconnect request ``` I also saw this on boot: ``` Sep 27 14:00:29 jik-x1 kernel: [ 3.405390] psmouse serio1: synaptics: Your touchpad (PNP: LEN0091 PNP0f13) says it can support a different bus. If i2c-hid and hid-rmi are not used, you might want to try setting psmouse.synaptics_intertouch to 1 and report this to linux-in...@vger.kernel.org. ``` The touchpad works for a second or two after it is reset and then stops working again. There are other bugs about this (e.g., https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1723986) but they claim the issue is fixed. To fix this I had to: 1. Remove `blacklist i2c_i801` from `/etc/modprobe.d/blacklist.conf`. 2. Update my initramfs after doing so. 3. Add `psmouse.synaptics_intertouch=1` to `GRUB_CMDLINE_LINUX_DEFAULT` in `/etc/default/grub`. 4. Update my grub configuration after doing so. 5. Reboot. Neither of these fixes by itself was sufficient.
