I have a solution that i've tested before. My problem was that the touchpad didn't work on start up, but only on log in. In the Xorg's log the SynPS/2 was recognised, but i suppose there may be a link problem with the driver, so i've adjusted the xorg configuration.
I've created a new empty /etc/X11/xorg.conf file and set the following rules in it: Section "InputClass" Identifier "Touchpad" # required MatchIsTouchpad "yes" # required Driver "synaptics" # required Option "MinSpeed" "0.5" Option "MaxSpeed" "1.0" Option "AccelFactor" "0.075" Option "TapButton1" "1" Option "TapButton2" "2" # multitouch Option "TapButton3" "3" # multitouch Option "VertTwoFingerScroll" "1" # multitouch Option "HorizTwoFingerScroll" "1" # multitouch Option "VertEdgeScroll" "1" Option "CoastingSpeed" "8" Option "CornerCoasting" "1" Option "CircularScrolling" "1" Option "CircScrollTrigger" "7" Option "EdgeMotionUseAlways" "1" Option "LBCornerButton" "8" # browser "back" btn Option "RBCornerButton" "9" # browser "forward" btn EndSection This is working perfectly for me, is not necessary set all commands like me only the required ones, perhaps the cause is a command line, in /usr/share/X11/xorg.conf.d/50-synaptics.conf, wrong and may be this: MatchDevicePath "/dev/input/event*" -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/868400 Title: Synaptics touchpad stops working To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-settings-daemon/+bug/868400/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
