Comment 22 for bug 320632

@John ,

Well as i said before :

Putting the right value - in my case - xinput set-int-prop 4 Synaptics Tap Action(303) 8 2 3 0 0 1 0 0
enables the tap-to-click.

Then I succeeded by typing "xinput set-int-prop 4 Synaptics Edge Scrolling (291) 8 1 1 1
to enable my edge scrolling.

But these changes come back to their initial value as soon as I reboot my pc.
What can I do to fix this ?

Then I went and saw that line in synaptics.c
who put the value at TRUE if double-tap isn't detected...
so i changed it to "TRUE" directly as does the patch that has been provided here...

my question is...then what ?? What I have to do to compile this so as to install it with apt-get ?

If it may help, i provide my xinput output.
