Subject: Lenovo X220 Touchpad + Trackpoint BIOS issue workaround ?
Date: Tue, 05 Apr 2011 09:53:04 -0500 [thread overview]
Message-ID: <4D9B2CD0.20404@canonical.com> (raw)
The Lenovo X220 has a touch pad and a track point. I would like to get
some clues as to if there is any work around in the kernel for the issue
I am seeing below:
Case 1: Touchpad and Trackpoint enabled in BIOS.
================================================
In this case the touchpad works correctly, but the trackpoint is not
detected at all. Some times after random number of reboots, the
trackpoint will start to respond approximately 15mts after X starts. But
the mouse will be detected as PS2 Generic Mouse.
Case 2: Touchpad Disabled Trackpoint Enabled in BIOS
======================================================
In this case the trackpoint works as expected, and it is detected as
TPPS/2 IBM TrackPoint.
[ 9.675396] input: TPPS/2 IBM TrackPoint as
/devices/platform/i8042/serio1/input/input9
I suspect this is a BIOS bug? Is it possible to work around this in the
kernel?
