I can't see any error messages in your log file that relate to the touchpad.
Have you checked whether the touchpad is enabled in System Settings?
Do you have xf86-input-mouse and xf86-input-keyboard installed? If you do, uninstall them. You should only have xf86-input-evdev and xf86-input-synaptics installed.
Do you have the file /etc/X11/xorg.conf or any files in the /etc/X11/xorg.conf.d/ directory? If you do, do any of them contain any lines relating to the touchpad? If any of them do, try commenting out all the lines relating to the touchpad and creating a separate file /etc/X11/xorg.conf.d/30-synaptics.conf containing the following:
- Code: Select all
Section "InputClass"
Identifier "touchpad"
Driver "synaptics"
MatchIsTouchpad "on"
Option "TapButton1" "1"
Option "TapButton2" "2"
Option "TapButton3" "3"
Option "VertEdgeScroll" "on"
Option "VertTwoFingerScroll" "on"
Option "HorizEdgeScroll" "on"
Option "HorizTwoFingerScroll" "on"
Option "CircularScrolling" "on"
Option "CircScrollTrigger" "2"
Option "EmulateTwoFingerMinZ" "40"
Option "EmulateTwoFingerMinW" "8"
Option "LeftEdge" "1700" # x coord left
Option "RightEdge" "5300" # x coord right
Option "TopEdge" "1700" # y coord top
Option "BottomEdge" "4200" # y coord bottom
Option "FingerLow" "25" # pressure below this level triggers release
Option "FingerHigh" "30" # pressure above this level triggers touch
Option "MaxTapTime" "180" # max time in ms for detecting tap
EndSection
and reboot. If there are no lines in /etc/X11/xorg.conf or /etc/X11/xorg.conf.d/* relating to the touchpad, create the above-mentioned file anyway, and see if it makes a difference after you reboot.
