Comment 45 for bug 191024

According to what you have written this is your touchpad:

udi = '/org/freedesktop/Hal/devices/platform_i8042_i8042_AUX3_port_logicaldev_input'
  info.capabilities = {'input', 'input.mouse'} (string list)
  info.category = 'input' (string)
  info.parent = '/org/freedesktop/Hal/devices/platform_i8042_i8042_AUX3_port' (string)
  info.product = 'PS/2 Logitech Wheel Mouse' (string)
  info.subsystem = 'input' (string)
  info.udi = '/org/freedesktop/Hal/devices/platform_i8042_i8042_AUX3_port_logicaldev_input' (string)
  input.device = '/dev/input/event8' (string)
  input.originating_device = '/org/freedesktop/Hal/devices/platform_i8042_i8042_AUX3_port' (string)
  input.product = 'PS/2 Logitech Wheel Mouse' (string)
  input.x11_driver = 'evdev' (string)
  linux.device_file = '/dev/input/event8' (string)
  linux.hotplug_type = 2 (0x2) (int)
  linux.subsystem = 'input' (string)
  linux.sysfs_path = '/sys/class/input/input8/event8' (string)

The only idea I have is checking BIOS setup - maybe there are some settings for touchpad you could change?
