[clug] problems with my Ubuntu

Hi Julian,

Check out the info on this page:

Much of that is about manual configuration by editing the
/etc/X11/xorg.conf file. which will give you access to set all options
(including the two finger drag to scroll, multifinger tap to
right/middle click, decreasing sensitivity to try to fix your random
clicking problem and so on).

For a GUI frontend you have 3 choices that I am aware of. None of
these will provide access to every option you can change by manually
editing xorg.conf, but they may be useful to change things on the fly
or experiment with touchpad sensitivity to find an optimal value that
won't randomally click:

* gsynaptics (Designed for GNOME, but as far as I can see it doesn't
have some advanced options like two or three finger tap).
* qsynaptics (Qt based but should work in Gnome, has two/three finger
tap option, but doesn't look like it has the ability to set touchpad
* ksynaptics (Designed specifically for KDE, and since it is a control
center module, probably won't help with GNOME, but keep it in mind in
case you ever install KDE).

If you want to use any of those programs, you will have to make one
manual modification to /etc/X11/xorg.conf file first, from a terminal
sudo gedit /etc/X11/xorg.conf

Then find the section starting with:
Section "InputDevice"
        Identifier      "Synaptics Touchpad"
And add the line:
        Option          "SHMConfig"     "on"
So all up that section should look like something like this:
Section "InputDevice"
        Identifier      "Synaptics Touchpad"
        Driver          "synaptics"
        Option          "SendCoreEvents"        "true"
        Option          "Device"        "/dev/psaux"
        Option          "Protocol"      "auto-dev"
        Option          "HorizScrollDelta"      "0"
        Option          "SHMConfig"     "on"
Save and close the file, then restart X - the easiest way to do this
is (SAVE YOUR WORK FIRST) probably the hot-key Ctrl+Alt+Backspace,
otherwise rebooting the computer will work.

Let me/the list know if you have any trouble with this, or need
something I have  said clarified.

On the day *I* go to work for Microsoft, faint oinking sounds will be
heard from far overhead, the moon will not merely turn blue but
develop polkadots, and hell will freeze over so solid the brimstone
will go superconductive.
