[edit] Abilitare il tapping sui touchpad Synaptic
Per abilitare il tapping è sufficiente editare il file /etc/xorg.conf.
su nano /etc/X11/xorg.conf
Sul terminale apriranno il file con l'editor. Per salvare il file una volta modificato utilizzare Control+O, per uscire Control+X.
Le modifiche da effettuare sono due. Anzi tutto va aggiunta una sezione di tipo "InputDevice":
Section "InputDevice"
Identifier "Synaptics Touchpad"
Driver "synaptics"
Option "AlwaysCore" "true" # send events to CorePointer
#Option "Device" "/dev/input/mice"
Option "Device" "/dev/psaux"
Option "Protocol" "auto-dev"
Option "SHMConfig" "false" # configurable at runtime? security risk
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
Option "VertEdgeScroll" "true" # enable vertical scroll zone
Option "HorizEdgeScroll" "true" # enable horizontal scroll zone
Option "CornerCoasting" "true" # enable continuous scroll with finger in corner
Option "CoastingSpeed" "0.30" # corner coasting speed
Option "VertScrollDelta" "100" # edge-to-edge scroll distance of the vertical scroll
Option "HorizScrollDelta" "100" # edge-to-edge scroll distance of the horizontal scroll
Option "MinSpeed" "0.75" # speed factor for low pointer movement
Option "MaxSpeed" "4.50" # maximum speed factor for fast pointer movement
Option "AccelFactor" "0.0020" # acceleration factor for normal pointer movements
Option "VertTwoFingerScroll" "true" # vertical scroll anywhere with two fingers
Option "HorizTwoFingerScroll" "true" # horizontal scroll anywhere with two fingers
Option "EmulateTwoFingerMinZ" "120" # this may vary between different machines
Option "TapButton1" "1"
Option "TapButton2" "2"
Option "TapButton3" "3"
EndSection
Quindi va modificata la sezione ServerLayout aggiungendo la riga che consente di caricare questo device, senza ovviamente cancellare quelle già presenti:
Section "ServerLayout"
...
...
InputDevice "Synaptics Touchpad" "SendCoreEvents"
EndSection
Allego di seguito il mio file xorg.conf, che mi consente l'uso del tapping su un portatile ACER 5920G.
