I have an Acer Aspire E5-573, with the Elantech touchpad.
The touchpad was working fine in 4.2.0. But for some reason cannot be activated now.
Output of xinput list
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ ELAN0501:00 04F3:300B Touchpad id=12 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]
↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)]
↳ Power Button id=6 [slave keyboard (3)]
↳ Video Bus id=7 [slave keyboard (3)]
↳ Power Button id=8 [slave keyboard (3)]
↳ Sleep Button id=9 [slave keyboard (3)]
↳ HD WebCam id=11 [slave keyboard (3)]
↳ AT Translated Set 2 keyboard id=13 [slave keyboard (3)]
↳ Acer WMI hotkeys id=14 [slave keyboard (3)]On the same machine, with Ubuntu 14.04 (3.13.0-73), the output is-
⎜ ↳ ETPS/2 Elantech Touchpad id=12 [slave pointer (2)]instead of ELAN0501:00 04F3:300B Touchpad.
I tried this -

But it did not work (and someone posted somewhere on the forum that dkms is unsupported for kernel 4.4).

Hi there,
You can quick check if your BIOS have a switch basic/advanced for the touchpad settings. On my Acer TMP236 I am only able to use it on basic since 4.4, no difference whatsoever.

Great, that restored the basic functionality!
Many thanks.

What if you try to blacklist psmouse ?
maybe it should load elan_i2c driver ...
current basic mode/psmouse module:
xinput:
Virtual core pointer id=2 [master pointer (3)]
↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
↳ ETPS/2 Elantech Touchpad id=11 [slave pointer (2)]
lsmod:
psmouse 118784 0
libps2 16384 2 atkbd,psmouse
serio 20480 6 serio_raw,atkbd,i8042,psmouse
Well...it's a driver bug who is built into kernel. Touchpad is not discovered via i2c bus, only as serio device(in case you have that bios switch), wait for a patch.
...
You should also try to blacklist only i2c-hid.

I have the same issue on an Acer E15. I tried blacklisting i2c_hid, hid_multitouch, mousedev, but none of them helped. The only thing that worked was to downgrade to 4.3.3.

Same issue for me, downgrading to 4.3.3 is the only way to make the touchpad work again.

Does this patch fix it?

4.4.2 has been released so the link no longer works (link to when it was in the stable queue)
https://git.kernel.org/cgit/linux/kerne … 1dab0e9496
4.4.2 should appear in testing soon
Edit:
link to the commit now in the 4.4.2 stable tree

Sorry, but what the hell do I do with that?

linux-4.4.2-1 is in testing right now and works perfectly on my Acer Aspire E15 w/ elantech touchpad. Just grabbed it from the arch packages repo and pacman -U installed it.
