Laptop Asus K52F met Ubuntu

Wireless LED

For the wireless LED you need to create two files and restart acpi. Follow this commands:

First file:

 sudo nano /etc/acpi/events/asus-wireless-switch

Code:

 event=hotkey ATKD 0000005d
 action=/etc/acpi/asus-wireless-switch.sh

Second file:

 sudo nano /etc/acpi/asus-wireless-switch.sh

Code:

 #!/bin/sh
 # Toggle wireless device on Asus K52 laptops
 WLANSTATUS=`cat /sys/class/ieee80211/phy*/rfkill*/state`
 
 test -z $WLANSTATUS && exit 1
 
 if [ $WLANSTATUS = 0 ]; then
 echo 0 > /sys/devices/platform/asus_laptop/wlan    
 elif [ $WLANSTATUS = 1 ]; then
 echo 1 > /sys/devices/platform/asus_laptop/wlan
 fi

Then run these commands:

 sudo chmod +x /etc/acpi/asus-wireless-switch.sh
 sudo service acpid restart
 sudo /etc/init.d/acpi-support restart

Touchpad

There is a solution to get the Elantech touchpad detected as such (and not ImPS/2 Logitech Wheel Mouse).

If the touchpad is not detected you just need to run this two commands:

 echo "options psmouse force_elantech=1" | sudo tee -a /etc/modprobe.d/psmouse.conf
 sudo rmmod psmouse && sudo modprobe psmouse

Then you can check your settings with "synclient -l" or with xinput list-props "ETPS/2 Elantech Touchpad" I made a startup script to keep two fingers tap as middle click, and three fingers tap as right click, with this command:

 xinput set-prop "ETPS/2 Elantech Touchpad" "Synaptics Tap Action" 0, 0, 0, 0, 1, 2, 3

Backup the '/root/asus-touchpad.sh' file and create a new file to get the touchpad button working permanent:

 sudo mv /etc/acpi/asus-touchpad.sh /root/asus-touchpad.sh
 sudo nano /etc/acpi/asus-touchpad.sh

Code:

 #!/bin/sh
 # Toggle Elantech touchpad device on Asus laptops
 
 [ -f /usr/share/acpi-support/power-funcs ] || exit 0
 
 . /usr/share/acpi-support/power-funcs
 
 getXconsole
 
 TPSTATUS=`xinput list-props "ETPS/2 Elantech Touchpad" | grep "Device Enabled" | awk '{ print $4 }'`
 
 test -z $TPSTATUS && exit 1
 
 if [ $TPSTATUS = 1 ]; then
 xinput set-prop "ETPS/2 Elantech Touchpad" "Device Enabled" 0
 notify-send -i /usr/share/icons/hicolor/scalable/actions/touchpad-enabled.svg -t 3000 "        TOUCHPAD OFF" "
      Press Fn+F9 to enable"
 elif [ $TPSTATUS = 0 ]; then
 xinput set-prop "ETPS/2 Elantech Touchpad" "Device Enabled" 1
 notify-send -i /usr/share/icons/hicolor/scalable/actions/touchpad-enabled.svg -t 3000 "        TOUCHPAD ON" "
      Press Fn+F9 to disable"
 xinput set-prop "ETPS/2 Elantech Touchpad" "Synaptics Tap Action" 0, 0, 0, 0, 1, 2, 3
 fi

Then run these commands:

 sudo service acpid restart
 sudo /etc/init.d/acpi-support restart

Configure the touchpad. Dash -> Touchpad.
