rimozione di un EndSection duplicato e aggiunta di un piccolo warning

New page

{{Warning|<center>'''Attenzione''' prestare molta cura a come si modifica il file xorg.conf e, possibilmente, farne prima una copia di backup, una modifica errata o un errore potrebbe impedire l'avvio del server X (e quindi dell'interfaccia grafica)!</center>}}
=Abilitare il tapping sui touchpad Synaptic=
Per abilitare il tapping è sufficiente editare il file /etc/xorg.conf.
{{Console| <pre class="clear">
su
nano /etc/X11/xorg.conf
</pre>}}
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":
{{Console| <pre class="clear">
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</pre>}}

Quindi va modificata la sezione ServerLayout aggiungendo la riga che consente di caricare questo device, senza ovviamente cancellare quelle già presenti:
{{Console| <pre class="clear">
Section "ServerLayout"
...
...
InputDevice "Synaptics Touchpad" "SendCoreEvents"
EndSection</pre>}}

Allego di seguito il mio file xorg.conf, che mi consente l'uso del tapping su un portatile ACER 5920G.
