Subject: Lenovo T460p touchpad and kernel 4.15.0
Date: Wed, 7 Feb 2018 12:31:30 +0000 [thread overview]
Message-ID: <20180207123130.GA24827@dubshen.astro.su.se> (raw)
Hi,
After switching to kernel 4.15.0 (openSUSE Tumbleweed 20180203) the touchpad of
my Lenovo T460p stops working after a resume/suspend cycle.
Comparing to old logfiles I found a notice
"Your touchpad (PNP: LEN2018 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-input@vger.kernel.org."
That's why I'm writing here now.
The old logfile (from kernel 4.14.15) had this notice from psmouse:
kernel: psmouse serio1: synaptics: queried max coordinates: x [..5676], y [..4758]
kernel: psmouse serio1: synaptics: queried min coordinates: x [1266..], y [1096..]
kernel: psmouse serio1: synaptics: Your touchpad (PNP:
LEN2018 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-input@vger.kernel.org.
kernel: psmouse serio1: synaptics: Touchpad model: 1, fw: 8.2, id: 0x1e2b1, caps: 0xf006a3/0x943300/0x12e800/0x10000, board id: 3053,fw id: 2010421
kernel: psmouse serio1: synaptics: serio: Synaptics pass-through port at isa0060/serio1/input0
rmi was not used in this version
Booting 4.15.0 shows the same, just without the notice, but further down also
kernel: input: Synaptics TM3053-006 as /devices/rmi4-00/input/input23
During resume I then get the following:
kernel: rmi4_smbus 8-002c: failed to get SMBus version number!
kernel: rmi4_physical rmi4-00: rmi_driver_reset_handler: Failed to read current IRQ mask.
kernel: rmi4_f01 rmi4-00.fn01: Failed to restore normal operation: -16.
kernel: rmi4_f01 rmi4-00.fn01: Resume failed with code -16.
kernel: rmi4_physical rmi4-00: Failed to suspend functions: -16
kernel: rmi4_smbus 8-002c: Failed to resume device: -16
kernel: rmi4_f03 rmi4-00.fn03: rmi_f03_pt_write: Failed to write to F03 TX register (-16).
which likely(?) is the reason for the non-working touchpad.
(The trackpoint is affected, too, BTW, but I don't use it)
If you need more info let me know (please via direct mail, I'm not on the list)
Regards,
Pit
