try checking touchpad settings here Start -> Settings -> System Settings -> Hardware -> Input Devices -> Touchpad |
touchpad not found... as I wrote the touchpad was working well after I had compiled PS2_ELANTECH on my old kernel (that I lost)
kde does not see any touchpad...

Install gentoo-sources:4.19.97 again and copy your linux-5.5.8-gentoo.config to linux-4.19.97-gentoo/
Hope that works, I never did a kernel downgrade |

I don't have Elantech stuff so cannot really help. There were soo many Elantech trouble cases here in the forums.

| Code: | xinput
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ <default pointer> id=6 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]

i did some debug and when i try to use 4 fingers I ve got this error....
| Code: | libinput debug-events
vent17 GESTURE_PINCH_BEGIN +25.971s 2
event17 GESTURE_PINCH_UPDATE +25.971s 2 19.08/13.14 (28.58/19.69 unaccelerated) 0.82 @ 1.48
event17 GESTURE_PINCH_END +25.993s 2
event17 - ETPS/2 Elantech Touchpad: kernel bug: Touch jump detected and discarded.
See https://wayland.freedesktop.org/libinput/doc/1.15.2/touchpad-jumping-cursors.html for details
|
but... it seems that libinput read in the correct way: if I try to scroll with two fingers, the output of debug are :
| Code: |
event17 POINTER_AXIS +55.586s vert -1.70/0* horiz 0.00/0 (finger)
|
or with mouse
| Code: |
event26 POINTER_AXIS +55.586s vert -1.70/0* horiz 0.00/0 (wheel)
|
....
now, why on the X it is not correct?

Did you read that reference?

As you're using libinput also for touchpad, what then is the reason for having synaptics as additional driver? |

One of the laptops here has CentOS 8 installed. It has Elantech touchpad.
If you're using X11 then this might help: | Code: | $ cat /etc/X11/xorg.conf.d/01-elantech-touchpad.conf
Section "InputClass"
Identifier "touchpad"
Driver "libinput"
MatchIsTouchpad "on"
Option "Tapping" "on"
Option "AccelerationNumerator" "6"
Option "AccelerationDenominator" "10"
Option "AccelerationThreshold" "1.2"
EndSection |
The said laptop runs KDE, and the KDE settings for inputs didn't show any touchpad settings... because, maybe, it didn't recognize it. By crafting the config (above) by hand I managed to get the touchpad working.
Although: | Code: | $ uname -r
4.18.0-147.5.1.el8_1.x86_64 |
I guess I wish you luck. :|

Do you have CONFIG_PINCTRL_AMD kernel config enabled?
Also there's a 2018 topic on Arch forums that might help you. Especially this post.

Hi there,
I recently got myself a laptop with one of these touchpads and had the same problem that scrolling was not working (and pressing a button via clicking the pad was very wonky, too). After searching for 2 evenings i finally found the one missing piece was HID_MULTITOUCH not being enabled in the kernel:
| Code: | │ Symbol: HID_MULTITOUCH [=y] │
│ Type : tristate │
│ Defined at drivers/hid/Kconfig:667 │
│ Prompt: HID Multitouch panels │
│ Depends on: INPUT [=y] && HID [=y] │
│ Location: │
│ -> Device Drivers │
│ -> HID support │
│ -> HID bus support (HID [=y]) │
│ (1) -> Special HID drivers |
Maybe this was also your problem. No other xorg.conf files were needed but it only works with INPUT_DEVICES="libinput". "evdev" does not do it.
