    Hi,

    Step 1) yum install gsynaptics

    Step 2) edit /etc/X11/xorg.conf
    make sure
    Option "SHMConfig" "on"
    is in the file in the Syanptics Section
    here is a copy of mine

    Section "InputDevice"
    Identifier "Synaptics"
    Driver "synaptics"
    Option "Device" "/dev/input/mice"
    Option "Protocol" "auto-dev"
    Option "Emulate3Buttons" "yes"
    Option "SHMConfig" "on"
    EndSection

    3.) System -> Preferences -> More Preferences -> Touchpad
    Adjust your settings to your liking

    4.) run synclient -l

    5.) Add values to the xorg.conf, Make sure to put option in front of each value

    good luck

    rucubed,

    Thanks for the post. I don't have the Touchpad control panel, can you post what rpm yours was installed from?

    Thanks!

    I believe it is in the Extras repo

    See step 1


    yum install gsynaptics

    Ahhhh...thanks for the tip. I finally got the annoying scrolling "feature" of the touchpad turned off. I guess it must have been designed for people with small fingers...definitely not me!

    Smile Synaptics Touchpad

    My First Post. I found this help for my touchpad on Toshiba Laptop. I cannot find it again to link to but I saved it on thumb drive. Who ever figured this out was my lifesaver after I installed FC9. He or She gets all the credit. Here it is.

    Hello all5horizons

    Welcome to the forum.

    To get clicking to work at all in Fedora at the moment you need to make some configuration changes.

    If you haven't done them so far then open a terminal window from the "applications menu - system tools" ( I assume you are running Gnome as your desktop). In the terminal window type:


    su -


    tap "Enter" and give your root password. This will give you a terminal window with full root (or administrator) control over your machine. Note the space and minus sign after su. They are very important, you won't get full root conrol without them.

    Type:


    gedit


    and enter. This will give you a text editor will full root priveliges.

    Use it to open the file:


    /etc/X11/xorg.conf


    Using the existing entries as a model, make sure that you have the following entries in the file. Any that aren't there then add them:


    Section "ServerLayout"
    Identifier "Default Layout"
    Screen 0 "Screen0" 0 0
    InputDevice "Keyboard0" "CoreKeyboard"
    InputDevice "TouchPad" "CorePointer"
    EndSection

    #Another section for Touchpad
    Section "InputDevice"
    Identifier "Touchpad"
    Driver "synaptics"
    Option "SendCoreEvents"
    Option "Protocol" "auto-dev"
    Option "TapButton1" "1"
    Option "TapButton2" "2"
    Option "TapButton3" "3"
    EndSection


    Reboot the machine and tapping should be enabled.

    Hy,

    I am following the "rucuped" post, so when i run the following code:
    synclient -l

    It says SHMConfig is disabled. Where can we enable the SHMConfig ?

    This is my xorg.conf

    # Xorg configuration created by pyxf86config

    Section "ServerLayout"
    Identifier "Default Layout"
    Screen 0 "Screen0" 0 0
    InputDevice "Keyboard0" "CoreKeyboard"
    EndSection

    Section "InputDevice"
    # keyboard added by rhpxl
    Identifier "Keyboard0"
    Driver "kbd"
    Option "XkbModel" "pc105"
    Option "XkbLayout" "fr"
    EndSection

    Section "Device"
    Identifier "Videocard0"
    Driver "radeon"
    EndSection

    Section "Screen"
    Identifier "Screen0"
    Device "Videocard0"
    DefaultDepth 24
    SubSection "Display"
    Viewport 0 0
    Depth 24
    EndSubSection
    EndSection

    Section "InputDevice"
    Identifier "Synaptics"
    Driver "synaptics"
    Option "Device" "/dev/input/mice"
    Option "Protocol" "auto-dev"
    EndSection

    Section "InputDevice"
    Identifier "Synaptics"
    Driver "synaptics"
    Option "Device" "/dev/input/mice"
    Option "Protocol" "auto-dev"
    Option "Emulate3Buttons" "yes"
    Option "SHMConfig" "on"
    EndSection

    Re: Synaptics Touchpad

    Thanks bmayo1, nearly 5 years later and using F17, your solution stopped my touchpad inadvertantly clicking links as I rolled over them.
