Thanks, all. It turns out on my XPS 13 that I was booted to the wrong kernel, which is why the PS/2 mouse device wasn't showing up. Once I booted into Aclean's test kernel the PS/2 device shows up in xinput.
My dmesg output is the same as what Hans is seeing. The psmouse module is loading up but fails to enable the mouse (which makes sense since we are in i2c mode)...just not sure why it wants to load in the first place. -- 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/1305522 Title: Backport Synaptics HID touchpad driver for 14.04 Status in “linux” package in Ubuntu: In Progress Status in “linux” source package in Trusty: In Progress Bug description: Synaptics just upstreamed a new set of HID touchpad driver: http://git.kernel.org/cgit/linux/kernel/git/jikos/hid.git/commit/?h=for-3.16/rmi4&id=9fb6bf02e3ad04c20edb8e46536ce3eeda32c736 It's better we can have it in 14.04 .
