Obviously I realise there are limitations with the hardware, but still doesn't stop me trying to make it better.
Hi.
I am using the Synaptics touchpad driver as well, and I have to say it works quite good now.
I have used it with Manjaro, openSuse and Ubuntu and they all behave pretty much the same, so I assume that the result works for all.
It is easy enough to set up, download the Xorg Synaptics driver, copy the .config file from /usr/share/X11/xorg.conf.d/70-synaptics.conf to /etc/X11/xorg.conf.d/70-synaptics.conf and modify it as you need.
Here are the synaptics parameter I have as an output from synclient:
Code:LeftEdge = 56 RightEdge = 1344 TopEdge = 49 BottomEdge = 865 FingerLow = 25 FingerHigh = 30 MaxTapTime = 250 MaxTapMove = 73 MaxDoubleTapTime = 180 SingleTapTimeout = 180 ClickTime = 100 EmulateMidButtonTime = 0 EmulateTwoFingerMinZ = 50 EmulateTwoFingerMinW = 5 VertScrollDelta = -33 HorizScrollDelta = -33 VertEdgeScroll = 0 HorizEdgeScroll = 0 CornerCoasting = 0 VertTwoFingerScroll = 1 HorizTwoFingerScroll = 0 MinSpeed = 1 MaxSpeed = 2.8 AccelFactor = 0.5 TouchpadOff = 2 LockedDrags = 0 LockedDragTimeout = 5000 RTCornerButton = 0 RBCornerButton = 0 LTCornerButton = 0 LBCornerButton = 0 TapButton1 = 1 TapButton2 = 3 TapButton3 = 0 ClickFinger1 = 1 ClickFinger2 = 3 ClickFinger3 = 2 CircularScrolling = 0 CircScrollDelta = 0.1 CircScrollTrigger = 0 CircularPad = 0 PalmDetect = 0 PalmMinWidth = 10 PalmMinZ = 200 CoastingSpeed = 20 CoastingFriction = 50 PressureMotionMinZ = 30 PressureMotionMaxZ = 160 PressureMotionMinFactor = 1 PressureMotionMaxFactor = 1 GrabEventDevice = 0 TapAndDragGesture = 1 AreaLeftEdge = 0 AreaRightEdge = 0 AreaTopEdge = 0 AreaBottomEdge = 0 HorizHysteresis = 8 VertHysteresis = 8 ClickPad = 1 RightButtonAreaLeft = 700 RightButtonAreaRight = 0 RightButtonAreaTop = 749 RightButtonAreaBottom = 0 MiddleButtonAreaLeft = 0 MiddleButtonAreaRight = 0 MiddleButtonAreaTop = 0 MiddleButtonAreaBottom = 0
And here is my /etc/X11/xorg.conf.d/70-synaptics.conf file:
Code:Section "InputClass" Identifier "touchpad catchall" Driver "synaptics" MatchIsTouchpad "on" # This option is recommend on all Linux systems using evdev, but cannot be # enabled by default. See the following link for details: # http://who-t.blogspot.com/2010/11/how-to-ignore-configuration-errors.html MatchDevicePath "/dev/input/event*" Option "VertScrollDelta" "-33" Option "HorizScrollDelta" "-33" Option "TapButton1" "1" Option "TapButton2" "3" Option "TapButton3" "0" Option "MinSpeed" "0.25" Option "AccelFactor" "0.5" Option "EmulateTwoFingerMinZ" "50" Option "EmulateTwoFingerMinW" "5" Option "synclient MaxTapTime" "250"
This could be tweaked further, but all in all I am quite happy with it. I have the suspicion that some parameter are set outside of the .conf file, maybe from the KDE touchpad settings, so dependent of the distro you use you might want to copy more parameter from the full list to your .conf file.
(Small side note, it would probably be better if the title of this thread would reference touchpad, rather than keyboard)
Thanks for your response surehand.
I ended up turning off Synaptics and just using libinput form the advice of others on this forum:
# Match on all types of devices but tablet devices and joysticks
Section "InputClass"
Identifier "libinput pointer catchall"
MatchIsPointer "on"
MatchDevicePath "/dev/input/event*"
Driver "libinput"
EndSection
Section "InputClass"
Identifier "libinput keyboard catchall"
MatchIsKeyboard "on"
MatchDevicePath "/dev/input/event*"
Driver "libinput"
EndSection
Section "InputClass"
Identifier "libinput touchpad catchall"
MatchIsTouchpad "on"
MatchDevicePath "/dev/input/event*"
Driver "libinput"
# This is the only "fancy" feature I have enabled: the right side of the
# touchpad emulates a scroll wheel on a mouse, press hard, move up and down.
Option "ScrollMethod" "edge"
EndSection
You're tempting me to go back to Synaptics and play around again now

Good point about the thread title, I'll try to change it.
