disable touchpad while typing has no effect

[dotnetCarpenter]

cinnamon --version: Cinnamon 4.4.8
Distribution: Linux Mint 19.3 Tricia 5.3.0-42-generic x86_64

Issue
Cinnamon Settings => Mouse and Touchpad => "Disable touchpad while typing" has no effect. I daily have the issue, that I am typing and hit the touchpad with my thumb, thereby selecting text up to the mouse pointer and then overwriting my text.
Usually I can solve it by ctrl+z but it is super annoying and is a huge distraction from my work.

Steps to reproduce
Probably you need to use the same driver as me. xserver-xorg-input-synaptics, xserver-xorg-input-libinput and xserver-xorg-input-all. Also, xserver-xorg-input-wacom is installed but I do not think it matters.

cat /proc/bus/input/devices:

I: Bus=0011 Vendor=0002 Product=0007 Version=01b1
N: Name="SynPS/2 Synaptics TouchPad"
P: Phys=isa0060/serio1/input0
S: Sysfs=/devices/platform/i8042/serio1/input/input5
U: Uniq=
H: Handlers=mouse1 event6 
B: PROP=15
B: EV=b
B: KEY=e520 10000 0 0 0 0
B: ABS=660800011000003

Press any character key and move the mouse via the touchpad while pressing (holding or repeatedly pressing).

Expected behaviour

Touchpad should be disabled while pressing any other key on the keyboard. And at least for 500ms.

Other information

Not sure if this is a problem in the settings file or if it is upstream.

I found that the same is true for "Disable touchpad when a mouse is attached". The option does nothing.

You shouldn't need the synaptics package. Just the libinput one should be sufficient. Can you remove that and re-check?

This works fine on my machine. To confirm, I installed synaptics, and the feature broke (after log out and in). They're both setting a property on the display server and perhaps that's confusing it.

I should see about requiring only one or the other in the packaging.

I have the same problem after updating to linux mint 20 on my laptop the touchpad does not turn off

On my machines, this setting works for GTK-based apps, but not for Qt-based apps. I tested this with Leafpad and it worked correctly, but it does not work in QtCreator.

Both Disable touchpad when a mouse is attached and Disable touchpad while typing are working as intended.

Is anyone still experiencing this issue? Thanks.

Do they work in Qt-based apps, too?

I'm on Arch Linux, and as of today, this option is not working with the Elan (ID 04f3:0c6e Elan Microelectronics Corp. ELAN:Fingerprint) touchpad on my Asus ProArt (intel version). Just trying to type this message is nearly impossible with the size of the touchpad under my right hand and it constantly taking input as i type.

Fedora 37 + Cinnamon, same issue. The cursor is doing it's magic while I am typing by me just hovering over the touch-pad not even touching it.

Fedora 41 + Cinnamon 6.4.8. Also experiencing this problem. It doesn't work no matter if Qt UI or not.
