[SOLVED] Elantech Touchpad Cound Not Move

I'm trying to set up graphic environment on a newly installed Artix, and just set up SDDM without any DE or WM and even fonts installed. There is a cursor showing up but it could not move. After googling for several hours, it still not work.

Firstly, I use a Clevo laptop with  Elantech touchpad, and I boot kerner without any parameters about i8042. I used to boot kernel with i8042.nomux=1 i8042.reset, i8042.reset or i8042.kbdreset=1, but none of them helped.

Normally, there are several lines about my touchpad in `dmesg -k`

psmouse serio2: elantech: assuming hardware version 4 (with firware version 0x6d4f02)
psmouse serio2: elantech: Synaptics capabilities query result 0x70, 0x16, 0x0c.
psmouse serio2: elantech: Elan sample query result 03, 06, 97
input: ETPS/2 Elantech Touchpad as /devices/platform/i8042/serio2/input/input17


Then, libinput list-devices could show following messages:

Device:          ETPS/2 Elantech Touchpad
Kernel:          /dev/input/event17
Group:            9
Seat:            seat0, default
Size:            99x54mm
Capabilities:    pointer gesture
Tap-to-click:    disabled
Tap-and-drag:    enabled
Tap drag lock:    disabled
Left-handed:      disabled

Calibration:      n/a
Scroll methods:  *two-finger edge
Click methods:    none
Disable-w-typing: enabled
Accel profiles:  none

If I start SDDM mannully with nothing in /etc/X11/xorg.conf.d, Xorg.0.log will show following messages.

(II) config/udev: Adding input device ETPS/2 Elantech Touchpad (/dev/input/event17)

dont worry, you are not alone :-)
https://bugs.archlinux.org/task/59714

try booting with kernel parameter "psmouse.elantech_smbus=0"  - for some peoples seems to fix it as well. (probably i8042.nomux=1 i8042.reset, i8042.reset or i8042.kbdreset - keyboard driver - will be no more necessary)

Sorry for replying late, but there is no error messages about elan_i2c in my dmesg, and I have tried this solution as laptop page of archwiki suggest it and surely it does not work.

I think I should try GDM later, as there are not apparently errors in logs and GDM dependents on more packages and may solve problems causing by lack of packages if there are any.

By the way, I'm not sure if something like follows shows the problem:

(II) No input driver specified, ignoring this device.
(II) This device may have been added with another device file.

so, chceck your xorg config files, if they are really set up correctly ;-)

Finally, I found a solution. This link tells three methods:

  • psmouse.proto=bare
  • psmouse.proto=imps i8042.reset i8042.nomux=1
  • echo -n 0x01 > /sys/devices/platform/i8042/serio2/crc_enabled

The last method was accepted and used to patch the kernel while first two methods introduced some problems. But for me, the last method does not work, and I tried the first method which works at least for the basic function.
