framework touchpad not recognizing scrolling or right click

[Jimmy2027]

The touchpad on my Framework Laptop 13 DIY Edition (13th Gen Intel) does not recognise scrolling or right clicks. Everything else (left click, cursor movement and taps) works fine.

I am using linux-6.6.8-gentoo-dist.

In /etc/portage/make.conf I have set:

Code: Select all

INPUT_DEVICES="libinput"

libinput list-devices shows that the touchpad is recognized as ImExPS/2 Generic Explorer Mouse which should indicate that the "Tigerlake HID-I2C driver is not loaded":

Code: Select all

Device:           ImExPS/2 Generic Explorer Mouse
Kernel:           /dev/input/event3
Group:            6
Seat:             seat0, default
Capabilities:     pointer
Tap-to-click:     n/a

Tap drag lock:    n/a
Left-handed:      disabled

Click methods:    none

Disable-w-trackpointing: n/a

This is the relevant /etc/X11/xorg.conf.d/40-libinput.conf part:

Code: Select all

Section "InputClass"
        Identifier "libinput touchpad catchall"
        MatchIsTouchpad "on"
        Option "Tapping" "True"
        Option "TappingDrag" "True"
        Option "NaturalScrolling" "True"
        #Option "ScrollMethod" "edge"
        Option "TappingButtonMap" "lmr"
        MatchDevicePath "/dev/input/event*"
        Driver "libinput"
EndSection

I had a look at the framework wiki page and saw that there

HID over I2C transport layer ACPI driver

is selected as built in while in my gentoo-dist kernel I have it as a module. Could that be the issue?

There is no Tigerlake HID-I2C module

There are two modules: One is CONFIG_I2C_HID_ACPI the other is a PINCTRL module. For Intel there exists some PINCTRL modules; one is CONFIG_PINCTRL_TIGERLAKE which is only needed if you have such a mainboard. Another would be CONFIG_PINCTRL_ALDERLAKE (and so on). Unfortunately you don't see with "lsmod" which one was loaded, because all these are statically configured in our kernel (and not as a module).

For a touchpad which is connected via i2c you will need i2c (almost every intel machine needs CONFIG_I2C_I801). i2c needs pinctrl (see above). And most touchpads need CONFIG_HID_MULTITOUCH also. Some notebooks use a DesignWare PCIe Controller, then this must be enabled also ...

... but AFAIK all these are included in our binary dist.kernel (and also in our GentooLiveCD) ... so please try a clean X11 configuration (means: delete all stuff you have configured in /etc/X11/xorg.conf.d).

If this does not help boot with an UbuntuLiveCD and check again ... maybe you have really a hardware problem.

(Maybe take a look to my german post: viewtopic-p-8692426.html#8692426 )

I took me a while but I finally found the time to boot with an UbuntuLiveCD... there scrolling and left click are working, so it should not be an hardware issue.

I also tried to delete all of my configurations in /etc/X11/xorg.conf.d, still the issue persists.

Is there anything else I could try?

Is there anything else I could try?

Please give us your kernel .config (please use wgetpaste for this) and the output of:
- lspci -nnk
- dmesg
