I'm currently running elementaryOS Freya on my Thinkpad T61 and want to use multi-touch gestures. Out of the box I can use 2-finger swipes for scrolling (although it works rather badly with this OS).
$ grep "TouchPad: buttons:" /var/log/Xorg.0.log
gives me this output:
(--) synaptics: SynPS/2 Synaptics TouchPad: buttons: left right middle double triple
so my touchpad is definitely capable of 3-finger gestures. However, I've tried for days now to get touchegg, ginn or xSwipe to work but when I enter the test-mode via touchegg or ginn in the terminal, it doesn't register any input at all, not even a simple tap.
Possible solutions that I've already tried include:
deactivating all native gestures in the synaptics driver
$ synclient VertTwoFingerScroll=0
$ synclient HorizTwoFingerScroll=0
$ synclient TapButton1=0
$ synclient TapButton2=0
$ synclient TapButton3=0
$ synclient ClickFinger1=0
$ synclient ClickFinger2=0
$ synclient ClickFinger3=0
$ synclient PalmDetect=0
$ synclient GrabEventDevice=0
using evdev driver instead of synaptics (in /etc/X11/xorg.conf as well as /etc/X11/xorg.conf.d/50-synaptics.conf)
Section "InputClass"
Identifier "evdev touchpad catchall"
Driver "evdev"
MatchDevicePath "/dev/input/event*"
MatchIsTouchpad "on"
Option "Protocol" "event"
Option "SHMConfig" "on"
EndSection
and downgrading to an older version of the synaptics driver as recommended in the installation instructions for xSwipe
$ sudo apt-get remove xserver-xorg-input-synaptics
$ sudo apt-get install build-essential libevdev-dev
$ autoconf automake libmtdev-dev xorg-dev xutils-dev libtool git libx11-guitest-perl
$ git clone https://github.com/felipejfc/xserver-xorg-input-synaptics.git
$ cd xserver-xorg-input-synaptics/
$ ./autogen.sh
$ ./configure --exec_prefix=/usr
$ make
$ sudo make install
I also installed touchegg in a xubuntu live environment to rule out incompatibility with elementaryOS.
