Solved Xorg: trackpoint works but trackpad does not

cracauer@ · May 27, 2024

On my Thinkpad T14 AMD I currently have the trackpoint working (the red button in the middle of the keyboard), but the trackpad is ignored. The trackpad buttons work normally.

Xorg.0.log doesn't seem to say why:

You haven't by change turned off the trackpad? There is a key combination (Fn-SomeKey) to do that on ThinkPads.

I don't see a key combo on this one. In the BIOS it is enabled.

Do you have a sysctl hw.psm.synaptics.touchpad_off?
(Don't know if that would influence the output of libinput)

On my T430s I have trackpad disabled in the BIOS, but trackpoint enabled. Shrug.

Hmmm, no, still no go.

I really need to focus on how to configure libinput to updo the

I think you can ignore those enabled properties (see also end of posting). I got the same, but the touchpad works just fine on a ThinkPad E15 AMD Gen3.

Rich (BB code):

Device:           ETPS/2 Elantech Touchpad

Size:             99x66mm

Click methods:    *button-areas clickfinger
Disable-w-typing: enabled
Disable-w-trackpointing: enabled
Accel profiles:   flat *adaptive custom
Rotation:         n/a

To rule out a hardware issue, have you checked the touchpad on other OSs?

You could try x11-drivers/xf86-input-synaptics instead.

My /usr/local/etc/X11/xorg.conf.d/libinput.conf

Code:

Section "InputClass"
    Identifier    "libinput Touchpad"
    MatchIsTouchpad    "on"
    Option        "NaturalScrolling" "on"
    Option        "Tapping" "on"
    Option        "TappingDrag" "on"
    Option        "TappingDragLock" "on"
EndSection
Section "InputClass"
    Identifier    "Middle Button Emulation"
    MatchIsPointer    "on"
    Option        "MiddleEmulation" "on"
EndSection

For example "Tapping" (Tap-to-click) or "TappingDragLock" is "on", but libinput list-devices shows as "disabled"

cracauer@ · May 29, 2024

I think it worked under Win10 when I got the laptop. But that install is retired. Lemme see whether I have a EFI Linux boot somewhere.

From & including:
[ 823.988] (II) event6 - SynPS/2 Synaptics TouchPad: device removed
you seem to have very similar output of the Xorg log compared to pacija here; Seems to work there, although with "auto power off" troubles. Noticable difference though, they have (from his Xorg og file):

Code:

[    67.551] (**) Option "_source" "server/udev"
[    67.609] (II) event6  - SynPS/2 Synaptics TouchPad: is tagged by udev as: Mouse Touchpad
[    67.612] (II) event6  - SynPS/2 Synaptics TouchPad: no resolution or size hints, assuming a size of 69x50mm
[    67.625] (II) event6  - SynPS/2 Synaptics TouchPad: device is a touchpad
[    67.626] (II) event6  - SynPS/2 Synaptics TouchPad: device removed

You have:

Code:

[   823.980] (II) event6  - SynPS/2 Synaptics TouchPad: is tagged by udev as: Mouse Touchpad
[   823.982] (II) event6  - SynPS/2 Synaptics TouchPad: no resolution or size hints, assuming a size of 69x50mm
[   823.987] (II) event6  - SynPS/2 Synaptics TouchPad: device is a touchpad
[   823.988] (II) event6  - SynPS/2 Synaptics TouchPad: device removed
[   823.988] (**) Option "TappingDrag" "on"
[   823.988] (**) Option "TappingDragLock" "on"
[   823.988] (II) libinput: SynPS/2 Synaptics TouchPad: Step value 0 was provided, libinput Fallback acceleration function is used.
[   823.988] (II) libinput: SynPS/2 Synaptics TouchPad: Step value 0 was provided, libinput Fallback acceleration function is used.
[   823.988] (II) libinput: SynPS/2 Synaptics TouchPad: Step value 0 was provided, libinput Fallback acceleration function is used.
[   823.988] (**) Option "NaturalScrolling" "off"
[   823.989] (**) Option "MiddleEmulation" "on"

Noticeble is:
[ 67.551] (**) Option "_source" "server/udev"
Which seems to come from a config file.
No idea what "Step value 0 was provided" means in relation to libinput or your touch pad.

EDIT: and you both seem to have the exact same touch pad device reference:
[ 823.989] (II) XINPUT: Adding extended input device "SynPS/2 Synaptics TouchPad" (type: TOUCHPAD, id 11)

cracauer@ · May 29, 2024

Solved. I tested and the trackpad didn't work under Linux Mint either.

So I tried all BIOS combinations even those which didn't make sense.

Turning the trackpad off in the BIOS makes it work.

A long term Suse employee that re-did everything about everything in Xorg input.

Among other things he's the reason why `xset led` doesn't work anymore.

For future reference this works on a T14s Gen4 AMD (21F8), thank you.
