Touchpad doesn't work
 
Hi LQ!

Must say, I am a total newbie - MY TOUCHPAD DOESN'T WORK!

I'm am using Ubuntu 5.04, Ksynaptics is installed. The funny thing is, while testing Ubuntu with the live cd, the touchpad worked perfectly, which is why I am so confused.

Can anyone help me?

Probably, your Ubuntu didn't configure your hardware correctly. You have just simply to modify/edit your /etc/X11/xorg.conf

On mouse "InputDevice" section
try to change your option to:

Option "Device" "/dev/psaux"
Option "Protocol" "PS/2"

Mmm... I think that it's better if you paste your xorg.conf here! ;)

Well, I tried changing it, so this was in the xorg.conf - Option "Protocol" "PS/2", but it didn't work, so here's the whole file:

# /etc/X11/xorg.conf (xorg X Window System server configuration file)
#
# This file was generated by dexconf, the Debian X Configuration tool, using
# values from the debconf database.
#
# Edit this file with caution, and see the /etc/X11/xorg.conf manual page.
# (Type "man /etc/X11/xorg.conf" at the shell prompt.)
#
# This file is automatically updated on xserver-xorg package upgrades *only*
# if it has not been modified since the last upgrade of the xserver-xorg
# package.
#
# If you have edited this file but would like it to be automatically updated
# again, run the following commands:
#
# cp /etc/X11/xorg.conf /etc/X11/xorg.conf.custom
# sudo sh -c 'md5sum /etc/X11/xorg.conf >/var/lib/xfree86/xorg.conf.md5sum'
# sudo dpkg-reconfigure xserver-xorg

Yeah.. I know how to fix it. You should have to modify your xorg.conf, just a lil' bit :D

Code:

Section "Module"
...
Load "synaptics"

modify the following section:
Code:

Section "InputDevice"
    Identifier "Configured Mouse"
    Driver "mouse"
    #Option "CorePointer"  <-- omit this line :)
    Option "Device" "/dev/input/mice"
    Option "Protocol" "ImPS/2"
    Option "Emulate3Buttons" "true"
    Option "ZAxisMapping" "4 5"
EndSection
    Section "InputDevice"
    Identifier "Synaptics Touchpad"
    Driver "synaptics"
    #Option "SendCoreEvents" "true" <-- omit this line
    Option "Device" "/dev/psaux"
    Option "Protocol" "PS/2"
    Option "HorizScrollDelta" "0"
EndSection

modify this section too:
Code:

Section "ServerLayout"
    Identifier "Default Layout"
    Screen "Default Screen"
    InputDevice "Generic Keyboard"
    InputDevice "Configured Mouse" "SendCoreEvents"
    InputDevice "Synaptics Touchpad" "CorePointer"
EndSection

In simple words, we just have to set synaptics touchpad as our core pointer. FYI, we can configure your synaptics touchpad on the fly if you enabled SHMConfig option. :D
I'm so sorry, i didn't watch this thread :D.

Good Luck

Just to share:
I had this experience with acer inspire 3003 and Ubuntu Breezy just today.
The suggestions above didn't help.

It was a puzzle since the touchpad was going fine up to a few hours ago.
Now - it is not unusual, on this machine, for the touchpad to stop going after hibernation. however, it normally goes after a reboot. This time, nothing doing.

In the end, I tried a complete power down (shutdown + remove all power including battery for 20 secs.) and this worked - touchpad going.
