Two finger scrolling on touchpad

Question

I can scroll with 2 fingers with my touchpad on Win7 but when I switch to Ubuntu 10.04 it doesn't work, the option is greyed out.

Could anyone help?

• My touchpad is Synaptics V7.2 PS/2 Port

Answer 1

In Ubuntu this option is disabled by default, go to System > Preferences > Mouse, in the Touchpad tab select "Two-finger scrolling" and that's done.

Answer 2

Try adding

synclient VertTwoFingerScroll=1
synclient HorizTwoFingerScroll=1
synclient EmulateTwoFingerMinW=5
synclient EmulateTwoFingerMinZ=48

to the end of your ~/.bashrc file and reboot (loging out and in again should also work).

Answer 3

If my previous answer didn't work for any reason it means there is a compatibility issue with the touchpad, to fix it you need to enable SHMConfig, to do it type in the terminal:

gksudo gedit /etc/X11/xorg.conf, in the file that will open add it:

Section "InputClass"
    Identifier "enable synaptics SHMConfig"
    MatchIsTouchpad "on"
    MatchDevicePath "/dev/input/event*"
    Option "SHMConfig" "on"
EndSection

If there is a Section "ServerLayout" in the file, add this line into it:

InputDevice     "SynapticsMouse1" "AlwaysCore"

Save the file, close it and reboot your system.

Then install these packages from the Universe Repository:

• gsynaptics
• synclient
• xserver-xorg-input-synaptics

After a reboot try enabling Two-finger scrolling through Mouse Preferences and if it's still impossible try in the terminal:

synclient -l , that will list every touchpad settings possible, then try some settings with this structure: setting=1 to enable and setting=0 to disable.

Eventually, if you didn't achieve nothing, see this Touchpad Troubleshooting Page and if any, report a bug.

I had the same problem when I was using 10.04. Basically I think there is a bug which doesnot show two finger scrolling option although it works in older package. I think you can enable the graphical button from gconf but it didnot help me then. Here are some questions I posted with some solutions:

Answer 5

I have tried few solutions but it didn't work however I found out that you can scroll placing one finger to the right of touchpad and going up or down.

Answer 6

From Ubuntu forums, you could try something like this.

xinput --set-prop --type=int --format=8  "SynPS/2 Synaptics TouchPad" "Synaptics Two-Finger Scrolling" 1 1
