| |
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?
