Subject: [PATCH 0/1] Input/trackpoint: Add new ELAN trackpoint device variant id 7
Date: Mon, 2 Nov 2026 21:08:35 +0800 [thread overview]
Message-ID: <20261102130836.11863-1-yaoyuan0329os@gmail.com> (raw)
The new ELAN trackpoint variant id 7 is found on thinkpad
X14 Gen1 laptop(Product Name: 21XMA006CD), it's now
incorrectly probed as Generic or Logitech PS/2 mouse but not
trackpoint.
Add ELAN variant id 7 to match the TP_READ_ID command return
value, probe the device as trackpoint correctly.
I tested the sensitivity/middle button lock/rate/resolution
setting, the trackpoint works well in daily usage and when
resume form system sleeping, no issue is found in my last
weeks usage.
BEFORE:
input: PS/2 Generic Mouse as /devices/platform/i8042/serio1/input/input63
AFTER:
psmouse serio1: trackpoint: Elan_variant7 TrackPoint firmware: 0xa1, buttons: 3/3
input: TPPS/2 Elan_variant7 TrackPoint as /devices/platform/i8042/serio1/input/input65
The patch is rebased to 7.4-rc1.
