When you try to use a Laptop with Igel and you have “Users”, you want to find a way to get the users happy. Because they complain about the touchpad. Yes, they have problems when they are writting and they touch it accidentally.
So, we have different ways to fix this.
- You can disable the trackpad using a policy.
But we have a problem here, what happens when the user forgets the external mouse? He can’t use the Touchpad.
Lets’s go to the next way.
2. You can use a script which detects if a usb mouse is plugged and then disables the Touchpad. If a user whants to use the touchpad again, he has 2 options:
1) An icon in his desktop called Touchpad
2) Hotkeys to enable or disable when they need.
To make this possible, we need 2 files:
Let’s see the touchpad.sh content.
# Enables the touchpad if and only if there aren't any external mice connected. # #Here you have to know the touchpad model TOUCHPAD="ETPS/2 Elantech Touchpad" TOUCHPAD2="SynPS/2 Synaptics TouchPad" TOUCHPAD3="PS/2 Generic Mouse" FOUND=0 for MOUSE in `find /sys/class/input -name mouse\*` do cat $MOUSE/device/name | grep -v "$TOUCHPAD" | grep -v "$TOUCHPAD2" | grep -v "$TOUCHPAD3" > /dev/null result=`echo $?` if [ $result -eq 0 ] then #echo "Found" FOUND=1 #Find a Mouse device other than the TouchPad and record the variable. break fi done DISPLAY=:0 export DISPLAY TOUCHPADDEVICE=$(($(xinput list | grep -i touchpad | cut -d= -f2 | cut -d[ -f1)+0)) #Find the Touchpad Id if [ $FOUND != 0 ]; then #If another device is founded, disable touchpad #echo "Disable" xinput disable $TOUCHPADDEVICE else #else enable touchpad #echo "Enable" xinput enable $TOUCHPADDEVICE fi
To configure the script properly, you need to know your touchpad id in your organization. We have several laptops, so we use 3.
To find your Touchpad model, just open a Terminal session in your laptop (not SSH), and type:
This name is what you have to insert in the script variable called TOUCHPAD.
Now, we upload the 2 files to the UMS as you want, in my example is /wfs/icon/mouse.png and /wfs/bin/mouse.sh
This path is totally personal, you can use your own path.
After uploading the 2 files, don’t forget to assign them where you want to use them.
Now, you have to create a new profile:
Don’t forget to check :
- Session Name
- Starting method Session (DESKTOP)
- Hotkey (I use Ctrl+Alt+R)
- Autostart (Very important, if we want to disable or enable at boot)
Finally, the path to the 2 files.
Just save the policy and apply it!
