ALPS touchpad detected as generic PS/2 Mouse

Hi,

I just installed Fedora 15 on my Dell E5420. I am having trouble with it detecting the touchpad as a touchpad. Initially the Touchpad part of System Settings>Input Devices was greyed out and now it does not exist at all. I have tried a few of the fixes I have found on other sites (mainly running the ALPS pad with Synaptics drivers) and nothing seems to work. The goal for me is to enable scrolling and to get rid of tap to click.

What I have done so far is:

1. Create a xorg.conf file using Xorg :1 -configure then moving it to the etc/X11 dir using cp xorg.conf.new /etc/X11/xorg.conf

2. Edit xorg.conf to look like this:
Section "ServerLayout"
Identifier "Default Layout"
Screen 0 "Screen0" 0 0
Screen 1 "Screen1" RightOf "Screen0"
Screen 2 "Screen2" RightOf "Screen1"
InputDevice "Touchpad" "CorePointer"
InputDevice "Keyboard0" "CoreKeyboard"
EndSection

Section "InputDevice"
Identifier "Touchpad"
Driver "synaptics"
# Device option should not be required
# Option "Device" "/dev/input/mice"
Option "Protocol" "auto-dev"
Option "SendCoreEvents"
Option "SHMConfig" "on"
Option "TapButton1" "1"
Option "TapButton2" "2"
Option "Emulate3Buttons" "yes"
Option "LeftEdge" "120"
Option "RightEdge" "830"
Option "TopEdge" "120"
Option "BottomEdge" "600"
Option "FingerLow" "14"
Option "FingerHigh" "15"
# Set MaxTapTime to 0 to disable tapping
# Option "MaxTapTime" "0"
Option "MaxTapTime" "180"
Option "MaxTapMove" "110"
Option "VertScrollDelta" "20"
Option "HorizScrollDelta" "20"
Option "AccelFactor" "0.030"
Option "MinSpeed" "0.5"
Option "MaxSpeed" "1.0"
EndSection

This I got from another site and just edited mine to be the same. I have tried also removing the # before # Option "Device" "/dev/input/mice" but it made no difference.

I've tried playing with the xorg.conf file a bit to no avail. Anyone able to help me out?

You might want to look at and possibly comment on the following bug report.

I personally do not have an ALPS touchpad, but rather a SYNAPTICS touchpad...

Thanks for the link. I've had a look at it but most of it is over my head. I've not had a lot of experience with the intricacies of Fedora before. I used Fedora 8 on a very superficial level to go on the internet and edit documents and the such but not much more.
