acpidump output
After enabling CONFIG_PINCTRL_AMD, the touchpad is recognized in `xinput --list`: Synaptics TM3336-001 id=11 [slave pointer (2)] Also, the touchpad does work randomly on some boots with this new option enabled, but then stops working after a bit of use. Interesting - when I do: `watch -n 0.2 head /proc/interrupts`, I see the touchpad events coming through on IRQ 3 and 7 instead of 12. See attached file. Created attachment 258483 [details]

dmesg output after i've gotten the touchpad detected, and it stops working
I would like to say that this issue is affecting me too. I have the exact same model and I am unable to get the touchpad to work. I am running a dual boot system with Windows10 and NixOS 17.09, with the 4.13.8 kernel. Touchpad works fine on Windows. No issues there. The touchpad is not seen at all by Linux. None of the utilities listed above see the touchpad. I haven't tried setting any kernel options, so I might still be able to fix this issue. I don't think that it will, but I want to try something. On the other hand, my USB mouse is seen just fine by Linux. So I can use that until the 4.14.x kernel is released, which I hope fixes this issue. As of kernel 4.14-rc5, I'm still having the same issue with my touchpad, FYI. This issue is resolved on my laptop as of kernel 4.14-rc7. It's likely that this pinctrl-amd update is what resolved it: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git/commit/drivers/pinctrl/pinctrl-amd.c?id=6afb10267c1692ada3a2903e31ea339917ad3ac0 |
Created attachment 258469 [details] dmesg output I have a Lenovo Ideapad 320-15ABR, (I found the exact model name with dmidecode). I'm having trouble getting the touchpad to work. It's not showing up in xinput --list or cat /proc/bus/input/devices. I'm using Linux 4.13.2, compiled with some extra debugging messages. Here's some relevant dmesg output when booted with i8042.nopnp. Without this option, I get the message: "i8042: PNP: PS/2 appears to have AUX port disabled, if this is incorrect please boot with i8042.nopnp" $ dmesg|grep psm [ 2.595815] bus: 'serio': add driver psmouse [ 2.627475] bus: 'serio': driver_probe_device: matched device serio1 with driver psmouse [ 2.627477] bus: 'serio': really_probe: probing driver psmouse with device serio1 [ 2.627482] psmouse serio1: no default pinctrl state [ 2.651584] psmouse: probe of serio1 rejects match -19 $ dmesg|grep i8042 [ 2.577522] i8042: PNP detection disabled [ 2.578648] Registering platform device 'i8042'.
