In my last post I explained were you found a tutorial for installing a real multitouch driver for the ACER 1825 and said I don’t know how to use these multitouch support. Thanks to Tom/drnessie who recommended ginn to me.
Ginn is a daemon which recognizes multitouch gestures with the ubuntu utouch interface and translates them to global or application specific shortcuts.
#if more libraries are missing the configure scripts prints it out
sudo make install
Next you need to specify the mapping from gestures to shortcuts. An example is inside the source package etc/wishes.xml. This file needs to be located in /etc/ginn/wishes.xml. Copy this file and configure it on your own or check my configuration:
I have added gestures for the webbrowsers opera,firefox and google-chrome, for Last.fm, gedit and xournal. More application are already defined.
In opera, firefox and chrome you could scroll in x and y direction with two finger dragging and zoom in/out with pinching.
In gedit/Texteditor you could scroll vertical with two finger dragging. In Last.fm application you could change volume with pinching and play next track with two finger right drag. In xournal you could scroll like in the browsers. I also specified the zoom/pinch gesture equal to the browser but on my system it does not work, I don’t know why, because its the same keyboard shortcut…? If somebody could help please write a comment.
Unfortunately our Acer 1825 is only a dual touch device and so you are a bit restricted with your gestures but you could use two finger dragging up,down,left,right, rotating left, rotating right and pinch spread and close.
Tipps for configuration:
I struggled a lot with the fact that the detection of the running applications is done with some strange matching of the name. The names seems to be language specific, therefore on my German ubuntu gedit is Texteditor. In my opinion the plain process name should be the better matching feature. If some gestures do not work on your system start ginn from terminal and do some gestures on your application and then look through the output from ginn how it named you application. This naming must be used inside the wishes.xml.
Start automatically ginn in tablet mode
This could be done by a simple edit on the gyro-key.run script from the last post:
pid=$( pgrep gyro-auto-rotat )
if [[ $1 == "activate" ]];then
#DO NOT START TWICE
if [ "$pid" == "" ] ;then
notify-send "gyro auto rotation enabled --> tablet mode"
if [[ $1 == "deactivate" ]];then
if [ "$pid" != "" ] ;then
kill -9 $pid
#reset screen to default
notify-send "gyro auto rotation disabled --> laptop mode"
notify-send "No param"
Let me know about your cool gestures. It works really nice. Try it out.
