[Solved]Touchpad stop working after pacman -Syu update ?

Hi, 
The touchpad was work out of the box, but after the last update ( which I think it has kernel, and xorg or xserver in it)  the touchpad stop working anymore.

Miraculously solved:  The touchpad suddenly work when I was playing around with xinput set-pointer for no reason. I tried set-input to touchpad but it gave me 5 lines of error ( which I forgot to saved) and worked since then.

Solved by installing xf86-input-synaptics.

If touchpad support without synaptics package is disabled, why isn't the synaptics package added as a dependency?

becase the package is needed only for those who have laptop smile


Give what you have. To someone, it may be better than you dare to think.

Thanks, that did it for me too. I thought it was a hardware error at first since it seemed too much of a simple problem to me, but after bumping into this thread I got curious. I actually thought my touchpad was dying on me roll

[stijn@hermes ~]$ dmesg |grep ALPS
input: AlpsPS/2 ALPS GlidePoint as /class/input/input7

For others, this was the exact command:

xinput set-pointer "AlpsPS/2 ALPS GlidePoint"

Of course with a 'real' Synaptics touchpad it will be different, but both Xorg's log and dmesg should be able to tell you what the name of the device is.
