Poster #83 got it right. The issue is caused by gnome-settings-daemon.
There is, however, no need to adjust/recompile any code.

Hi, I was having the same issue. I believe that the Synaptics touchpad
driver and Gnome both disable the touchpad individually. For some
reason, Gnome (in particular gnome-settings-daemon) fails to re-enable
it; which is why you end up with a dead touchpad, once you disable it.

Here is what fixed it for me (HP Pavilion DV6730ec):

First of all, open a terminal. Press Alt+F1 to open the applications
menu and choose the Terminal application from the accessories or use an
external mouse to so.

To bring your touchpad back to life, enter the following command:

Code:

gconftool --type bool --set
/desktop/gnome/peripherals/touchpad/touchpad_enabled true

The key "/desktop/gnome/peripherals/touchpad/touchpad_enabled" is where
gnome-settings-daemon remembers that you disabled your touchpad. This is
the reason, why it is disabled even after a reboot.

The issue will re-appear, next time you disable your touchpad. You need
to prevent gnome-settings-daemon from disabling your touchpad in the
first place, because the Synaptics touchpad driver does this already. To
do so, run the following command in a terminal:

Code:

gconftool-2 --type string --set
/apps/gnome_settings_daemon/keybindings/touchpad ""

This dissociates the key to lock your touchpad from gnome-settings-
daemon. If for any reason, the latter command breaks the lock touchpad
support for you, than you probably have a different issue. To re-
associate the key with gnome-settings-daemon, run this command:

gconftool-2 --type string --set
/apps/gnome_settings_daemon/keybindings/touchpad XF86TouchpadToggle

Hope this helps. I recommend rebooting after this procedure and check if
this really fixed it for good. I noticed that the error only occurs only
once after a reboot.
