Title:
Elantech Touchpad not working on Fujitsu E5410
Status in xserver-xorg-input-libinput package in Ubuntu:
Confirmed
Bug description:
The Fujitsu E5410 (model type 5E14A1 according to the bottom sticker)
is supplied with an Elantech(?) Touchpad. This apparently requires
i2c_hid and does not properly work in Ubuntu 20.04. It seems also to
interfere with the (internal) keyboard.
Problem behavior:
booting Ubuntu 20.04 with kernel 5.11.0-27:
keyboard works, touchpad is not recognized.
Running sudo modprobe i2c_hid manually from a terminal sometimes results in
the touchpad working. Sometimes however the keyboard does not recognize any
input anymore. After rebooting, approx 1/2 times the keyboard is not working
anymore.
Making sudo modprobe i2c_hid permanent via /etc/modules-load.d/
permanently crashes the keyboard on startup such that it is impossible
to log in.
booting with kernel 5.14.0-1004-oem:
sudo modprobe i2c_hid has no effect, the touchpad is never recognized.
Booting with this kernel, 9/10 times the keyboard is not recognized at all and
one cannot log in. Permanently loading the module via /etc/modules-load.d has
no effect.
booting with kernel 5.14.9-051409 (a mainline kernel from
ppa:tuxinvader/lts-mainline ):
modprobing the i2c_hid module has no effect. The keyboard works.
probably not just xserver-xorg-input-libinput but also i2c_hid is
affected. However w.r.t.
https://wiki.ubuntu.com/DebuggingTouchpadDetection and without being
able to further diagnose the problem I filed this bug against xserver-
xorg-input-libinput.
