noob tip for debian..

[Wakou]

I am 100% Linux and Debian noob, so when I finally got installed to my quite old Hp Pav Laptop, I was very indeed to find the touchpad was unusably slow, and I could not play with the new box of tricks. A bit of googlery came up with this. Rember these are effectively the first commands I had ever issued in linux, so I was a bit to say the least. However:

Debian And Slow Touchpad Ho adottato un clueless user

The Problem: some touchpads are REALLY slow under Debian, you have to tap like a piano player to get the little arrow from one window to another.

And yes, this is really annoying since everything works fine with an USB mouse.

Even worse, you didn’t notice the problem with an Ubuntu installation. But you don’t want any brown hot nasty things on your precious laptop.

The solution was here. Maybe you’ve got an ALPS touchpad, not a Synaptics one! Eureka! lampadina

Wanna know what to do? Read on! happy

help «Wonderful. How do I know wether it’s an ALPS or not?»

Easy. Type this in your shell

cat /proc/bus/input/devices

Here’s the relevant part of my output (on a Fujitsu-Siemens Lifebook S2110):

I: Bus=0011 Vendor=0002 Product=0008 Version=7322
N: Name=”AlpsPS/2 ALPS GlidePoint”
P: Phys=isa0060/serio4/input0
S: Sysfs=/class/input/input5
H: Handlers=mouse2 ts2 event4
B: EV=f
B: KEY=420 670000 0 0 0 0
B: REL=3
B: ABS=1000003

help «My output is similar, I do have an ALPS. What should I do?»

Assuming that you’ve already installed the Synaptic driver, you only have to open /etc/X11/xorg.conf and set the “Protocol” option to “alps”in the touchpad section.

sudo nano /etc/X11/xorg.conf

Here’s mine:

Section "InputDevice"
Identifier “Synaptics Touchpad”
Driver “synaptics”
Option “SendCoreEvents” “true”
Option “Device” “/dev/psaux”
Option “Protocol” “alps”
Option “HorizScrollDelta” “0″
Option “SHMConfig” “true”
EndSection

Save with CTRL+O, close nano with CTRL+X and restart the X server by hitting the CTRL+ALT+BACKSPACE keys and enjoy a F1-speeding arrow :o)

Worked perfect first time!
