Acer 5920G Media Keys and Ubuntu 7.10

In principle, when you install Ubuntu, the media keys (with blue lights) are activated, as the second (scrolling capable) part of the touchpad, which ends up being very annoying, and to disable that feature we have to do this:

1) Add this line to the file /etc/xorg.conf, in the section of Synaptic driver,

Option "SHMConfig" "true"

so it looks like this

Section "InputDevice"
Identifier "Synaptics Touchpad"
Driver "synaptics"
Option "SendCoreEvents" "true"
Option "Device" "/dev/input/event4"
Option "Protocol" "auto-dev"
Option "SHMConfig" "true"
Option "HorizEdgeScroll" "0"

save the file

2) Install the package qsynaptics, and run it, (not necessarily as root)

$ qsynaptics

Press the “off” button to deactivate the media keys, and then press OK saving the configuration.

3) Go to System -> Preferences -> Sessions

and create a new ‘startup’ entry:

Name: Qsynaptics – Configure Touchpad
Command: qsynaptics -r

And save it. Now when you log in, settings are applied correctly (-r loads the previously saved .qsynaptics file)
