Pro to aby rozhodit touchpad na notebook'u nebo jinem zarizeni potrebujete dodat do konfiguraci jadra nasledujuci volby

.config

  [*] Provide legacy /dev/psaux device
  [*] Event Interface

Po restartu musite pomoci [dmesg] uvidet neco:

   -> multifinger detection
   -> palm detection

Pak dodame balik synaptic pomoci prikazu:

emerge synaptics

Přidáme synaptics do make.conf:

/etc/make.conf 
 USE="synaptics"
 INPUT_DEVICES="evdev keyboard mouse synaptics"

Dodame do konfiguraci nasledujici radky:

/etc/X11/xorg.conf 
Section "InputDevice"
 Identifier	"Touchpad"
 Driver		"synaptics"
 # Driver		"mouse"
 Option		"Protocol"		"auto-dev"
 Option		"Device"		"/dev/psaux"
 Option		"ZAxisMapping"		"4 5"
 Option		"LeftEdge"     		"1900"
 Option		"RightEdge"     	"5400"
 Option		"TopEdge"       	"1800"
 Option		"BottomEdge"   	 	"3900"

 Option		"MinSpeed"		"0.02"
 Option		"MaxSpeed"		"0.18"
 Option		"AccelFactor" 		"0.0010"
 Option		"UpDownScrolling"	"on"
EndSection

Pokud se chystate pouzivat jeste extereni mysovy ovladac, tak asi uz mate pro ni sekce:

/etc/X11/xorg.conf 
 Section "InputDevice"
    Identifier	"Mouse1"
    Driver	"mouse"
    Option "Protocol"    "IMPS/2"
    Option "Device"      "/dev/psaux"
    Option "ZAxisMapping" "4 5"
    Option "Buttons" "5"
 EndSection

Naposled musite zmenit sekci server layout: 

 Section "ServerLayout"
   Screen "Screen 1"
    InputDevice "Mouse1" "CorePointer"
    InputDevice "Touchpad" "SendCoreEvents"
    InputDevice "Keyboard1" "CoreKeyboard"
 EndSection
Pozor: Jako corepointer mame mys, ne tochpad!


Poznámka: Pri obnoveni xorg, nekdy je potrebne preinstalovat synaptics, pokud xserver nemuze najit modul synaptics. Take jsou problemy pri pouzivani v USE hardened.
