I am having exactly the same problem with the touchpad after upgrading to 14.10, a solution was suggested in Synaptic touchpad on laptop not working after update
the manual solution of executing always works:
sudo modprobe -r psmouse
sudo modprobe psmouse proto=imps
but unfortunately I cannot make it permanent. I created the file psmouse.conf as it was suggested but the error remains, the touchpad is not working after rebooting. I have to plug a USB mouse and manually run in a terminal
sudo modprobe -r psmouse
sudo modprobe psmouse
This time I didn't include the parameters to check if the options would be taken from the file and it seems like it does, the touchpad works perfectly after those commands. But I don't understand why those options are not taken during the booting phase.
Finally I decided to add these two lines to the rc.local, but I dont like this workaround...
any idea why the settings in psmouse.cong are not taked during the booting phase?
thanks a lot. Jose
