Getting the “double tap on the led to disable touchpad” to work in linux - Envy 14.
While I’m loving my new notebook (Hp Envy 14), it doesn’t play completely nice with Linux yet. Like there is an led on the envy’s touchpad, on which you can double tap to toggle touchpad on/off. That functionality isn’t supported out of the box and requires patches to both the kernel and the synaptics touchpad driver.
Synaptics driver patch (for 1.4.0)
Kernel patch (for the LED support - 2.6.38)
If you’r using arch linux, there’s an older version of the driver in the AUR. Here’s the v1.4.0 version I compiled after applying the patch (for x86_64) - xf86-input-synaptics-1.4.0-1-x86_64.pkg.tar.xz
After install, you may want to increase the MaxDoubleTapTime to around 300 in the synaptics config file as the default value is set too low. Next up, to get the suspend working properly (it’s the radeon driver thats causing it to fail).
