Do some touchpads have no sensitivity settings?

General system Kernel, boot, graphics & hardware
1

My touchpad is very sensitive, even hovering above it counts as a touch

For some reason all the sensitivity settings are disabled (It’s not because I’m on wayland or using libinput, I am using synaptics on xorg)

Changing the finger high and finger low in the config file does nothing. I also get an error when I attempt to adjust the synaptics finger settings via xinput. All the other settings work on both

Even the gui settings on KDE has the sensitivity settings greyed out while everything else works.

Is there something I can change in the bios, or some firmware I can install to make sensitivity available or does the hardware simply not have that option?

2

Is the touchpad enabled in the other tab?

3

Yes. It works fine and all the settings work except for pressure/sensitivity

I even tried it just now on libinput and the few settings that are able to be adjusted work fine except for sensitivity

I think it’s probably the hardware not having pressure sensors or something. Perhaps the firmware was configured that way

Settings you should look are here maybe.

xinput list

sudo libinput list-devices
5

I went through those

When I “–set-prop” everything works fine except for the sensitivity setting on xinput which is “synaptics finger”. It says device not found

Same thing happened when I was entering the command for sensitivity in libinput, it gave some error message about a module not being found

Unfortunately you’ll have to spend the time going through it in order to figure it out. There is no generic solution i know of.

Yeah, I’ll keep trying, thanks. It’s an interesting learning experience

@Archnoob
What is your hardware anyway? Post the link.

Here is more info on libinput!

Is this what you have for xorg file?
Edit: Do you have this package installed?

xf86-input-synaptics

Set up custom xorg file?

/etc/X11/xorg.conf.d/70-synaptics.conf

Yes, I am using the xorg version or gnome at the moment with the synaptics driver

I’ve edited the 70-synaptics config file many times to fine tune the touchpad and every setting works except for finger low and finger high. I can put it at 5 and 10 or 95 and 100 and it doesn’t change the sensitivity

Same thing with synclient. I even put it up to like 900 there and it didn’t change anything

13

Here’s what happens when I try to change the sensitivity on xinput. It says device not found, but it only does that for code 346 which is the finger low and high

What kind of touchpad is it?

15

Maybe this helps? :man_shrugging:

https://help.ubuntu.com/community/SynapticsTouchpad#Default_clickpad_gestures

16

I don’t know, it just says synaptics any time I check the hardware info

I noticed on the xinput properties that beside synaptics capabilities the verticlal and horizontal resolution aren’t available with this touchpad. Maybe that was something to do with it

Synaptics Capabilities (374): 1, 0, 0, 1, 1, 0, 0

17

Is that coming from this?

xinput list-props "SynPS/2 Synaptics TouchPad"

18

Do you have the touchpad indicator extension installed on gnome? Not sure if it’s any help?

Here:
https://extensions.gnome.org/extension/131/touchpad-indicator/

19

I’ll take a look at that link

I think there are no pressure sensors on this touchpad though. I just tried measuring with libinput and this is what happened
