Bug 483224

Description of problem:
On my Lenovo x301 laptop, which has a TrackPad and a TrackPoint (the little red ball), the TrackPoint's speed and sensitivity can't be configured when the TrackPad is enabled in the BIOS. If the TrackPad is disabled in the BIOS, the TrackPoint's speed and sensitivity can be configured with the usual method:

echo -n 120 > /sys/devices/platform/i8042/serio1/speed 
echo -n 250 > /sys/devices/platform/i8042/serio1/sensitivity

These files simply don't exist when the TrackPad is enabled in the BIOS


Version-Release number of selected component (if applicable):
[Steven@x301 ~]$ rpm -qa | grep hal
hal-0.5.12-14.20081027git.fc10.x86_64
hal-cups-utils-0.6.17-4.fc10.x86_64
hal-libs-0.5.12-14.20081027git.fc10.x86_64
hal-info-20081219-1.fc10.noarch
hal-devel-0.5.12-14.20081027git.fc10.x86_64


How reproducible:
Probably on every Lenovo x200, x300 and x301 laptop.


Steps to Reproduce:
1. Enable the TrackPad in the BIOS
2. Go to /sys/devices/platform/i8042/serio1/
3. See that the speed and sensitivity files are missing

  
Actual results:
The TrackPoint seems incorrectly detected by HAL when the TrackPad is enabled in the BIOS. It detects a "DualPoint Stick" when it should detect a "TPPS/2 IBM TrackPoint".


Expected results:
Both devices should work independently and show up in /sys/devices/platform/i8042

Here is the lshal output for both situations, plus a directory list:
