IdeaPad 5 15are05 - elan touchpad not working on 20.04 nor on 18.04
Solution 1
I found the solution, big shoutout to dl3it on Ideapad 5-15ARE05: Touchscreen not working | Lenovo Forums. (Note: it says touchscreen, but that's just the name of the touchpad I guess. It works fine.)
The problem is that the kernel does something wrong with the drivers. To fix this, you will have to install a mainline kernel and configure it yourself.
First off, install dependencies by executing this on a command line:
sudo apt-get install libncurses-dev flex bison openssl libssl-dev dkms libelf-dev libudev-dev libpci-dev libiberty-dev autoconf
Then, download kernel 5.6.x or 5.7.x (x can be any integer, I used 5.7.1 and it has been tested on 5.6.14 and 5.7.0-rc7) from source (via kernel.org). Once on kernel.org, click on [tarball]
for the kernel you want.
Extract everything as you would do with any other .tar.gz
file.
Then, move to the linux-5.6.x
or linux-5.7.x
directory in a command line.
Execute sudo make menuconfig
and navigate to Device Drivers → Input device support → Touchscreens → Elan eKTH I2C touchscreen.
Once there, change the asterisk to an m
by hitting enter and then typing the m
.
After that, use the left and right arrows to change the selected option in the bottom to "save" and hit Enter. Then, you will want to save it as .config
(which it should default to).
Now still being in the same directory, execute this command:
sudo make -jx && sudo make modules_install -jx && sudo make install -jx
(Change x
to the amount of threads your CPU has. Leaving out this option will make this take a long time.)
This will take some time, but after it's finished, you will want to make sure your PC will boot on the new kernel. To do that, execute:
sudo update-initramfs -c -k <kernel-version>
(Change <kernel-version>
to the kernel version you just installed, for example 5.7.1
.)
Then, fix the grub config by executing:
sudo update-grub
And then reboot and your touchpad should work just fine!

Solution 2
It seems not to be possible to blacklist elants_i2c
driver, as it is a built-in kernel module for Ubuntu:
stefano@stefano-IdeaPad-5-15ARE05:~$ modinfo elants-i2c
name: elants_i2c
filename: (builtin)
license: GPL
description: Elan I2c Touchscreen driver
author: Scott Liu <[email protected]>
so there is a faster way than compiling the kernel. Just create a SystemD unit like the below:
stefano@stefano-IdeaPad-5-15ARE05:~$ cat /etc/systemd/system/touchpadfix.service
[Unit]
Description=Fix touchpad issue by binding correct driver
[Service]
ExecStart=/usr/local/bin/touchpadfix
Type=oneshot
RemainAfterExit=yes
[Install]
WantedBy=multi-user.target
and create /usr/local/bin/touchpadfix
file as follows
stefano@stefano-IdeaPad-5-15ARE05:~$ cat /usr/local/bin/touchpadfix
#!/bin/bash
modprobe i2c_hid
echo "i2c-ELAN0001:00" > /sys/bus/i2c/drivers/elants_i2c/unbind
echo "i2c-ELAN0001:00" > /sys/bus/i2c/drivers/i2c_hid/bind
and then make it executable, enable and start the unit with the following commands:
chmod +x /usr/local/bin/touchpadfix
sudo systemctl daemon-reload
sudo systemctl enable --now touchpadfix.service
and touchpad should start to work immediately!

Solution 3
Almost 100% correct, here is the workaround.
Open Terminal
sudo mousepad /etc/default/grub
Edit as follows: GRUB_CMDLINE_LINUX="initcall_blacklist=elants_i2c_driver_init"
Save, exit mousepad or text editor of your choosing.
sudo update-grub
Add before or after 'quiet splash' does NOT MATTER.
Keep in mind this is a 'workaround' that will get the touchpad working, touchpad indicator icon will NOT work properly.
Solution 4
I was able to resolve this issue using the advice from this launchpad bug comment (via this Lenovo forum reply):
Jasper van der Neut - Stulen (neutstulen) wrote on 2020-06-18: #31
As a workaround you can add
"initcall_blacklist=elants_i2c_driver_init"
toGRUB_CMDLINE_LINUX
, runupdate-grub
, power down the laptop and start it again.
This also works when booting from installation media, by adding initcall_blacklist=elants_i2c_driver_init
to the boot parameters. In grub's load screen, I added it after quiet splash
when editing the Start Ubuntu option.
Solution 5
An easier solution is: add "blacklist elants_i2c" to /etc/modprobe.d/unneeded-modules.conf (you'll have to create this), save and reboot. Working on identical touchpad and Manjaro. Vendor=04f3 Product=3140 Version=0100

I bought a Lenovo IdeaPad 5 15are05 yesterday and installed Ubuntu 20.04 on it. Problem is, the touchpad doesn't work.
I've also tried 18.04 and even Debian 10, but the only OS it works on is Windows.
I've looked through many fora and I found nothing that helped me. However, I did find some commands and I think you will find these outputs interesting
cat /proc/bus/input/devices
:I: Bus=0018 Vendor=0000 Product=0000 Version=0000 N: Name="Elan Touchscreen" P: Phys= S: Sysfs=/devices/platform/AMDI0010:01/i2c-1/i2c-ELAN0001:00/input/input4 U: Uniq= H: Handlers=mouse0 event4 B: PROP=2 B: EV=b B: KEY=400 0 0 0 0 0 B: ABS=661800001000003
Even though it says "Touchscreen", I know for a fact that this is my touchpad. How do I know this? Well, when I go to a terminal using
ctrl+alt+f3
, and I try to use my touchpad, it outputs this:elants_i2c i2c-ELAN0001:00: unknown packet 0e 00 04 03
03 meaning that I'm touching it. That value changed on different actions, for example, it becomes 01 on 'releasing' the touchpad.This means that the touchpad is listed under ELAN0001, which the "Touchscreen" is listed under as well. I don't think it's that weird that it says it's a touchscreen, because they're very similar.
xinput
outputs this:⎡ Virtual core pointer id=2 [master pointer (3)] ⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)] ⎜ ↳ NEWMEN1500 Mouse Consumer Control id=13 [slave pointer (2)] ⎜ ↳ NEWMEN1500 Mouse id=15 [slave pointer (2)] ⎣ Virtual core keyboard id=3 [master keyboard (2)] ↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)] ↳ Power Button id=8 [slave keyboard (3)] ↳ AT Translated Set 2 keyboard id=11 [slave keyboard (3)] ↳ Video Bus id=7 [slave keyboard (3)] ↳ Power Button id=6 [slave keyboard (3)] ↳ NEWMEN1500 Mouse Consumer Control id=14 [slave keyboard (3)] ↳ NEWMEN1500 Mouse id=12 [slave keyboard (3)] ↳ Integrated Camera: Integrated C id=9 [slave keyboard (3)] ↳ Ideapad extra buttons id=10 [slave keyboard (3)]
The touchpad should be listed under Virtual core pointer, but it isn't.
I would really like to know a fix for this, since I need the touchpad to work and I don't want to buy a new laptop, so please help me!

Tim Richardson about 4 yearsBased on the Phoronix benchmarking on this hardware, you need 5.6 kernel or later. Google 'Ubuntu mainline kernel '
-
Kelvin Bouma about 4 years@TimRichardson I just tried kernel 5.6.17 and 5.7.1 and they both do not want to boot and I also still get unknown packet errors when trying to use my touchpad
-
Kelvin Bouma about 4 years@TimRichardson Update: I got 5.7.1 to work. However, the touchpad still doesn't work, it also is not listed in /proc/bus/input/devices anymore
-
Tim Richardson about 4 yearsIs your hardware the same as phoronix.com/…
-
Kelvin Bouma about 4 years@TimRichardson no it isn't, mine has a Ryzen 5 4500U. Mine is an IdeaPad 5 15are05 and that one is an IdeaPad 5 (14)
-
Tim Richardson about 4 yearsHI, that hardware is I think virtually identical to the system Phoronix tested. I am getting one in two or three weeks (for my son)
-
Kelvin Bouma about 4 years@TimRichardson well, with touchpad it's a lot different, but I found the solution, I will now post it as the answer to my question. I hope you get it working for your son too!

Tim Richardson about 4 yearsthanks for this effort. When I get the new ideapad as mentioned above, I will add my feedback, in case it is needed.
-
Imaskar about 4 yearsThanks, that really helped. 2 small notes: strip the debug symbols with ´INSTALL_MOD_STRIP=1´ or the image will be 1gb+; and ´make clean´ after.

Walf almost 4 yearsI should have included this in my answer because editing the installer's grub line was not permanent, and I had to do this after the first normal boot, too.

WhosUrDaddy almost 4 yearsmousepad is a text editor, just like gedit, only a little more lightweight. Its the default on some flavors of linux. You can replace 'mousepad' with your favorite text editor.

67hz over 3 yearsI have had multiple machines needing this fix, and in both cases I needed to add pci=nocrs to GRUB_CMDLINE_LINUX_DEFAULT in ADDITION to adding this blacklist command to GRUB_CMDLINE_LINUX? Reference: askubuntu.com/a/1303168/9578

mLstudent33 over 3 yearsdid not work so tried @rik-shaw 's advice as well, still does not work on my ideapad 3 but I'm loading my Ubuntu 20.04 on external SSD that came out of my Thinkpad T420. Does anyone know what to do in my situation?
-
mLstudent33 about 3 yearsafter a couple of reboots, it started working.
-
mLstudent33 about 3 yearsIt started working after a few days, maybe a few reboots but on my new installation tried rebooting 3 times but not working yet so maybe in a few more reboots.
-
mLstudent33 about 3 yearsit works if you do the pci=nocrs as @rik-shaw states above.
-
opinion_no9 about 3 yearsThanks! The idea (with modifications) helped on a Fujitsu E5510. Touchpad, Wifi and ethernet and keyboard did not start! Better result with Ubuntu 21.04(!). What eventually helped in my case: Create a Systemd service essentially invoking "modprobe i2c_hid" (not more) . . Do not forget the "sudo systemctl enable" part! FF!
