libinput ignores Option "DisableWhileTyping"

#1 Post by yoshi »

My touchpad is always in the way when typing -
I also have tapping activated, so I type random characters all over the place...

The Option "DisableWhileTyping" in /etc/X11/xorg.conf.d/30-touchpad.conf should fix
that according to my research.

Code: Select all

 $ more /etc/X11/xorg.conf.d/30-touchpad.conf
Section "InputClass"
    Identifier "touchpad"
    Driver "libinput"
    MatchIsTouchpad "on"
    Option "Tapping" "on"
    Option "DisableWhileTyping" "true"
EndSection

Code: Select all

$ xinput list
⎡ Virtual core pointer                    	id=2	[master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer              	id=4	[slave  pointer  (2)]
⎜   ↳ ELAN0630:00 04F3:3072 Touchpad          	id=10	[slave  pointer  (2)]
⎜   ↳ ELAN0630:00 04F3:3072 Mouse             	id=11	[slave  pointer  (2)]

Code: Select all

$ xinput list-props 10
Device 'ELAN0630:00 04F3:3072 Touchpad':
	Device Enabled (176):	1
	...
	libinput Natural Scrolling Enabled Default (321):	0
	libinput Disable While Typing Enabled (322):	1
	libinput Disable While Typing Enabled Default (323):	1
	...
Just it doesn't ....
I can still type and tap and scroll and move the mouse while typing.
Any suggestions?

Re: libinput ignores Option "DisableWhileTyping"

#2 Post by j2mcgreg »

I have a deep aversion to touchpads, so I disable them at my first opportunity and always use a mouse instead.
HP 15; ryzen 3 5300U APU; 500 Gb SSD; 8GB ram
HP 17; ryzen 3 3200; 500 GB SSD; 12 GB ram
Idea Center 3; 12 gen i5; 256 GB ssd;

In Linux, newer isn't always better. The best solution is the one that works.

I use touchpad-indicator (in the repos) to take care of that on my Lenovo.

In fact it's already set to disabled by default.

In case you'd like to turn back to (the good old) Synaptics (at least to try) :

Code: Select all

sudo mv /etc/X11/xorg.conf.d/30-touchpad-libinput.conf{,.old} ; sudo apt update ; sudo apt install xserver-xorg-input-synaptics -y
Reboot.


To revert back to libinput (for whatever reason) :

Code: Select all

sudo mv /etc/X11/xorg.conf.d/30-touchpad-libinput.conf.old /etc/X11/xorg.conf.d/30-touchpad-libinput.conf ; sudo apt remove xserver-xorg-input-synaptics -y
Reboot.

Not trying to be too intrusive, and posting for three reasons, one missed? two curious as to why synaptics would be in the boot parameters when using libinput, mouse too when using touchpad.

splash psmouse.synaptics_intertouch=0 ipv6.disable=1 potential issue?
EDIT - I'm not suggesting to change it - as per post #8, just curious (two) as to why they'd be used with libinput and a mouse. :smile:

viewtopic.php?p=769837#p769837 three maybe?

Cheers!

tried that one, but gives me at least one second before the touchpad gets disabled after keystroke and also blocks way longer than configured.
So it's lagging beyond usability :(

@Charlie Brown & @MXRobo

I used to use synaptic - but for some reason from time to time the touchpad would
freeze.
I tried all kind of stuff to fix it - that's why the boot parameter is still there. Historic...

What would work is the following script which I would call from CLI when the touchpad freezes:

Code: Select all

  	module=i2c_hid; 	#touchpad freezes after suspend 

    	#sudo 
    	modprobe -r  $module  &&\

    	#sudo 
    	modprobe  $module &&\
    	 echo "$module reloaded successfully";
Since switching to libinput in MX-Tweaks no freeze - but unfortunately also no disable while typing.

As @MXRobo suggested, I changed the boot parameters by removing the synaptic stuff and rebooting...

modified the touchpad-indicator source code
(python) according to this post:

https://github.com/atareao/Touchpad-Ind ... -487394655

now the lag is gone and it disables the keyboard.
I wonder if it is related how the keyboard is connected
in the laptop...
I read that USB keyboards are considered external and don't trigger the disable ... my keyboard might be internally connected via USB

but doesn't matter - my problem is solved, even if I wasn't able to do it without an additional external program

Very well done!

We will want to test that for possible use with MX more generally. Would you be willing to provide a link to your patched code?
