HP Touchpad on/off button not working (Synaptics touchpad)

Hey guys. 
My laptop has a dedicated button to turn the touchpad on/off. However, on ArchLinux is not working. It's more like a sensor; I have to double-tap it in order to enable/disable touchpad (under Windows). Now, I can only enable/disable the touchpad using synclient TouchpadOff=1/0.
Also, the TouchPad led is not working: it should be orange when the touchpad is off, and white when it is on.


I forgot to say that xf86-input-synaptics 1.5.0-1 is already installed.

Thanks!

Archie,

Are you trying to turn it off during specific events (during typing, etc) or after you plug in a mouse...?

Which DE/WM are you using? I use KDE and installed the synaptiks package that has automated the on/off of my touchpad based on events. For example, I plug in a mouse, it disables the touchpad; when I type, it disables the touchpad, etc.

Cheers,
Czar.

It isn't a dedicated button, but rather an area on the touchpad where you tap to disable it (I doubt it is even a sensor). A little light comes on to indicate that the touchpad is disabled.

I have the same scheme, but on mine it doesn't work either. It hasn't been one of my big priorities, so I haven't really looked into it. I think it is posible with synaptics to get it to work, but probably not with the little light. Sorry pal.

I have an HP G42-475DX and have never had the light on the touchpad work for me. On some of the other distros it works, but I imagine that it is a bit more work than it is worth at this point. I have never had it working on Arch and since I got synaptiks configured, I had no need to press on to try and get it working.

Cheers,
Czar.

Does this button generate an event in xev?

You can map any key/button that generates events to a script that will use synclient to toggle the touchpad on and off.

My laptop has a dedicated button to turn the touchpad on/off.

If you want the double-tap to work, and the LED to light up on modern HP clickpad/touchpad you need to
install xf86-input-synaptics-led and synaptics-led respectively, from AUR.


You need to install an RTFM interface.

Been there, done that.

Still not working after months!

Read this thread where another owner eventually got the functionality to work https://bbs.archlinux.org/viewtopic.php?id=142108. There's a patch involved for some HP models like mine, details are in the thread.
