LAPTOP Toshiba A70 Touchpad

[ventura_b]

Toshiba Laptop A70 use one chip, i8042, for keyboard and touchpad. It did a ps2 emulation for both devices. I had a lot of problems to set my touchpad, even with tons of informations at importants websites. You can find all informations about the configuration of this laptop with a search but this one is hard to find:

You need to disable =legacy USB support= in the bios.

Turn off the laptop, press power to turn on and hit F2 key to open the BIOS menu. At (Legacy USB support) check DISABLED.

The touchpad do not work with this function enabled at the BIOS. You do not have a touchpad working without disabling this function.
The laptop Toshiba A70 use the chip i8042 for keyboard and touchpad, if this function is enabled at BIOS the touchpad don`t works. When you disable the legacy USB support, at boot time you can see two devices at /proc/bus/input/device, KBD and Mouse. The kbd is the /dev/input/event0 and mouse is the /dev/input/event1. You need to check EVDEV at the kernel.

Of course, emerge synaptics, check your configuration:

use a nice xorg.conf, or copy this one (change the device to /dev/input/event1)

and check the synaptics master:

if you use KDE check this:

I hope this help people to avoid all the problens and time consunption I had.

O laptop Toshiba A70 usa um chip, o i8042, tanto para o teclado como para o mouse touchpad. Se na BIOS estiver ativado (enabled) a função LEGACY USB SUPPORT o touchpad não funciona nem com reza brava. Depois de desabilitado o maledeto código, no boot aparece o AUX e o KBD separado no /proc/bus/input/device, nesse caso o /dev/input/event0 é o teclado e o /dev/input/event1 é o touchpad. Lembrando que o kernel deve ser configurado com EDEV.
