I managed to install Ubuntu 16.04 on my asus ux501 vw, but some of my shortcut are not working. I'm not looking to fix them all, but just one : the shortcut which allow me to enable or disable touchpad, so i can write long documents with working about the touchpad.
I tried to find it on google but I got nothing.
Can someone explain me how to fix that please? Thanks !
I created this bash script from negusp's answer. It finds and toggles TouchPad device. You can configure a custom shortcut to it in system settings.
#!/bin/bash
read TPdevice <<< $( xinput | sed -nre '/TouchPad/s/.*id=([0-9]*).*/\1/p' )
state=$( xinput list-props "$TPdevice" | grep "Device Enabled" | grep -o "[01]$" )
if [ "$state" -eq '1' ];then
xinput --disable "$TPdevice" && notify-send -i emblem-nowrite "Touchpad" "Disabled"
else
xinput --enable "$TPdevice" && notify-send -i input-touchpad "Touchpad" "Enabled"
fi
I'm setting Ctrl+Shift+F9 for toggle touchpad enable and disable like this:
Edit: You may need to make your script to executable with command chmod +x filename or input /bin/bash /filepath to Command field of Custom shortcut window.
grep and sed. You can easily consolidate the two to sed -nre '/TouchPad/s/.*id=([0-9]*).*/\1/p'.

zenity --info --text "Touchpad DISABLED" --timeout=2 and zenity --info --text "Touchpad ENABLED" --timeout=2 to your if and else blocks, respectively, to pop up a window which announces the new state then autocloses in 2 sec.

You want shortcut, but you can easily put 2 scripts on the desktop and execute them.
First, go to terminal. Type xinput.
Output Example:
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ SynPS/2 Synaptics TouchPad id=12 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]
↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)]
↳ Power Button id=6 [slave keyboard (3)]
↳ Video Bus id=7 [slave keyboard (3)]
↳ Power Button id=8 [slave keyboard (3)]
↳ Sleep Button id=9 [slave keyboard (3)]
↳ Laptop_Integrated_Webcam_1.3M id=10 [slave keyboard (3)]
↳ AT Translated Set 2 keyboard id=11 [slave keyboard (3)]
↳ Dell WMI hotkeys
Find the Touchpad. In this example, the touchpad is listed as id=12
Create the first script with this:
#!/bin/bash
xinput enable 12
Save it and name it touchpadenable.sh, and in terminal, mark it as executable with:
chmod +x touchpadenable.sh
Do the exact same thing again, but rename the file as touchpaddisable.sh (or whatever), and instead of
xinput enable 12
Use the command
xinput disable 12
Save, mark as executable, and you should be able to run the scripts from the desktop. Note: you may have to right-click the scripts, click properties, and allow it to be executed.
You must to do like negusp's answer, first check your touch device, and will shows something like this:
~$ xinput
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ PixArt Dell MS116 USB Optical Mouse id=10 [slave pointer (2)]
⎜ ↳ SynPS/2 Synaptics TouchPad id=14 [slave pointer (2)]
⎜ ↳ DLLC6B2:00 06CB:75BF Touchpad id=12 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]
↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)]
↳ Power Button id=6 [slave keyboard (3)]
↳ Video Bus id=7 [slave keyboard (3)]
↳ Power Button id=8 [slave keyboard (3)]
↳ Sleep Button id=9 [slave keyboard (3)]
↳ Integrated_Webcam_HD id=11 [slave keyboard (3)]
↳ AT Translated Set 2 keyboard id=13 [slave keyboard (3)]
↳ Dell WMI hotkeys id=15 [slave keyboard (3)]
↳ DELL Wireless hotkeys id=16 [slave keyboard (3)]
In my case is the device with id=12, now create a bash script with name "toggle-touch" in you Desktop folder under a folder named "bin", would be "~/Desktop/bin" and copy next code, check the device variable is pointed to my touch id=12, fix it with your case:
#!/bin/bash
device=12
state=`xinput list-props "$device" | grep "Device Enabled" | grep -o "[01]$"`
if [ $state == '1' ];then
xinput --disable $device
else
xinput --enable $device
fi
Set to this script execution permission:
chmod 775 /Desktop/bin/toggle-touch
Finally you can add this path to the ".bashrc" from your home folder, just add this line to the end of file:
PATH=$PATH:~/Desktop/bin
update the path with:
. .bashrc
Then you can execute this script from any place, I hope this help.
Leaving my script here (more or less the same as above). Works out of the box, no need for prior lookup of the device ID.
#!/bin/bash
function query_device_id {
xinput list | grep -i touchpad | sed 's/.*id=\([0-9]*\).*/\1/g'
}
let device_id=$(query_device_id)
let state=$(xinput list-props $device_id | grep Enabled | awk '{print $4;}')
let new_state=$((1 - $state))
xinput set-prop $device_id "Device Enabled" $new_state
Create a shell script and paste below code in to it and name it touchPadDisable.sh
#!/bin/bash
temp=$(xinput | grep -i "Elantech Touchpad" | cut -d"=" -f 2 | cut -d"[" -f 1)
xinput disable $temp
Create another shell script and paste below code in to it and name it touchPadEnable.sh
#!/bin/bash
temp=$(xinput | grep -i "Elantech Touchpad" | cut -d"=" -f 2 | cut -d"[" -f 1)
xinput enable $temp
First script will disable touchpad and second one will enable touchpad.
You can add this script to custom shortcuts in keyboards.
In my Ubuntu 18.04 Almas Dusal's answer didn't work until I changed the 'p' to lower case in TouchPad in the following line of his code:
read TPdevice <<< $( xinput | sed -nre '/Touchpad/s/.*id=([0-9]*).*/\1/p' )
After that touchpad was succesfully disabled and enabled by the script but that was not reflected in the Mouse & Touchpad settings screen. I created the following new script which toggles the touchpad while updating the settings view.
#!/bin/bash
state=$( gsettings get org.gnome.desktop.peripherals.touchpad send-events )
if [ "$state" = "'enabled'" ];then
gsettings set org.gnome.desktop.peripherals.touchpad send-events 'disabled' \
&& notify-send -i touchpad-disabled-symbolic "Touchpad" "Disabled"
else
gsettings set org.gnome.desktop.peripherals.touchpad send-events 'enabled' \
&& notify-send -i input-touchpad-symbolic "Touchpad" "Enabled"
fi
Do like @Almas Dusal's answer, which does like @negusp's answer, except use my modified script instead:
read TPdevice <<< $( xinput | sed -nre '/TouchPad/s/.*id=([0-9]*).*/\1/p' )
state=$( xinput list-props "$TPdevice" | grep "Device Enabled" | grep -o "[01]$" )
if [ "$state" -eq '1' ];then
xinput --disable "$TPdevice"
zenity --info --text "Touchpad DISABLED" --timeout=2
else
xinput --enable "$TPdevice"
zenity --info --text "Touchpad ENABLED" --timeout=2
fi
Now, assign it a shortcut key of Ctrl + Alt + P (or whatever you choose [the 'P' stands for touch'P'ad in my case]). My addition to the script above is the zenity self-closing popup window part, which I describe more in my answer here (https://superuser.com/a/1310142/425838).
Now, when I use the shortcut above, I see this popup window, which auto-closes after 2 seconds:
And if I press it again I get this popup window, which auto-closes after 2 seconds:
Perfect!
As an added bonus, if you are a heavy mouse user, just add the command which calls your script above to your startup programs in Ubuntu so it runs and disables your track pad every time your computer starts up! I have this set so I can quit bumping the track pad with the base of my hand and deleting stuff accidentally all the time! Now, when my hand bumps the track pad, nothing happens because it's disabled. :)
Note: this all works great in Ubuntu 18.04 as well as older versions. I've tested it in Ubuntu 18.04 and Ubuntu 14.04. Here's a screenshot from the shortcut settings window in 18.04:
