Comment 0 for bug 893839

I have an alps touchpad on my laptop Acer 7741 laptop. It never got detected as a touhpad in ubuntu <= 11.04. Finally with 11.10, it finds it as a touchpad and in the mouse config I can see a touchpad tab.

Changing the settings in the mouse config do nothing.

xinput -list gives:

 Virtual core pointer id=2 [master pointer (3)
  ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
  ↳ HP Wireless Optical Mobile Mouse id=9 [slave pointer (2)]
  ↳ AlpsPS/2 ALPS GlidePoint id=13 [slave pointer (2)]
  ↳ PS/2 Mouse id=12 [slave pointer (2)]

(HP optical is my external mouse)

I can modify the sensitivity of the touchpad when I change the PS/2 mouse settings with xinput.

Changing any of the settings in the touchpad tab of the mouse GUI util has no effect.

Disabling the PS/2 mouse disables the touchpad.
Disabling the AlpsPS/2 glidepoint does nothing.

When I do
dmesg | grep -i input I get:

[ 17.613230] input: PS/2 Mouse as /devices/platform/i8042/serio1/input/input11
[ 17.638723] input: AlpsPS/2 ALPS GlidePoint as /devices/platform/i8042/serio1/input/input12

blacklisting psmouse disables the touchpad.

I can use the tapping and movement features of the touchpad....but side-scrolling, multi-touch and most importantly, disable touchpad when typing does not work. These all work in windows.
