So work has given me a new shiny Dell System XPS L322X (the ubuntu dev model) which i quickly installed gentoo on (personal preference). When i went to go and paste something using the Cypress two button track pad, it did not work.

damn.

Here is the fix:

first things first, lets make sure that your kernel settings are correct.

Device Drivers  --->
  Input device support  ---> 
    [*]   Mice  ---> 
       [*]     Cypress PS/2 mouse protocol extension 

now lets check our settings using xinput:

 % xinput
⎡ Virtual core pointer                          id=2    [master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer                id=4    [slave  pointer  (2)]
⎜   ↳ CyPS/2 Cypress Trackpad                   id=12   [slave  pointer  (2)]
⎣ Virtual core keyboard                         id=3    [master keyboard (2)]
    ↳ Virtual core XTEST keyboard               id=5    [slave  keyboard (3)]
    ↳ Power Button                              id=6    [slave  keyboard (3)]
    ↳ Video Bus                                 id=7    [slave  keyboard (3)]
    ↳ Power Button                              id=8    [slave  keyboard (3)]
    ↳ Sleep Button                              id=9    [slave  keyboard (3)]
    ↳ Laptop_Integrated_Webcam_1.3M             id=10   [slave  keyboard (3)]
    ↳ AT Translated Set 2 keyboard              id=11   [slave  keyboard (3)]

as we can see, our device is #12, so lets list props on #12:

AHH – you see it ??
Synaptics Middle Button Timeout (266): 0

lets change that to 1:
xinput --set-prop 12 "Synaptics Middle Button Timeout" 1

now restart X and Voila!! all done.
