I Installed Mint on my Lenovo 14wGen2 yesterday and I haven't been able to use my touchpad on it. The pad is functional, but Mint doesn't seem to detect it (doesn't even appear with xinput).
#Mint doesn't "see" my touchpad

Wdym the pad is functional? Like it works, but not in LM?
jade pagoda
exactly
it works in my BIOS settings for example
OH btw i checked in these and its not the problem
apparently its a problem with the touchpad itself
i found this thing in a forum
The Lenovo 14w Gen 2 touchpad may not work under Linux due to issues with the Elan Touchpad driver. Here are some findings: The Elan Touchpad is not listed by xinput or lspci: In some cases, the Elan Touchpad is not detected by xinput or lspci, complicating troubleshooting. Presence in sys/bus/acpi/devices: However, the Elan Touchpad is sometimes listed in /sys/bus/acpi/devices, which indicates that the kernel recognizes the device. Kernel module issues: Compiling a newer kernel or adding boot options may not resolve the issue, as it appears to be related to the Elan Touchpad driver.
but i have no clue what that means
modest pivot
What's the output of inxi -JLMxxx? Also, uname -a.
jade pagoda
first command gives this
uname -a just says "Linux mekane 6.8.0-58-generic #60-Ubuntu SMP PREEMPT_DYNAMIC Fri Mar 14 18:29:48 UTC 2025 x86_64 x86_64 x86_64 GNU/Linux"
modest pivot
Try updating to a newer kernel in Update Manager >> Kernel.
jade pagoda
alright
modest pivot
If nothing goes, please look for a relevant entry in cat /proc/bus/input/devices.
modest pivot
What do you mean? Have you installed the kernel update already? And performed a restart?
jade pagoda
i did
i didn't know i just had to reboot
it should be good now
alright yeah i got the latest kernel
the touchpad still doesnt work :/
jade pagoda
If nothing goes, please look for a relevant entry in `cat /proc/bus/input/device...
uhhhh
modest pivot
It's a lot innit?
modest pivot
That's... all?
jade pagoda
...yup
modest pivot
How about this? cat /sys/class/input/event*/device/name
jade pagoda
doesnt seem to give anything more

How... the fuck.
jade pagoda
a common solution i found was to install synaptics but idk if that'll do anything
especially considering your reaction i think ive got bigger problems
modest pivot
If you know the package name, won't hurt to give it a go.
grim star
a common solution i found was to install synaptics but idk if that'll do anythin...
synaptics is old and deprecated
jade pagoda
oh
modest pivot
Try adding blacklist elan_i2c to the end of your /etc/modprobe.d/blacklist.conf too.
modest pivot
synaptics is old and deprecated
It is suggested to check out synaptics in such case that unexpected behaviour is encountered with libinput.
grim star

if his system is like old I guess it might help
modest pivot
You may refer to Linux Mint documentation with that too.
jade pagoda
Try adding `blacklist elan_i2c` to the end of your `/etc/modprobe.d/blacklist.co...
that didnt work
modest pivot
Try to do this with your /etc/default/grub.
GRUB_CMDLINE_LINUX="i8042.kbdreset=1"
Maybe to see how things are also like, try booting to a live environment of Ubuntu Cinnamon 25.04 and/or Fedora. See if that works over there.
jade pagoda
Try to do this with your `/etc/default/grub`.
`GRUB_CMDLINE_LINUX="i8042.kbdrese...
huh it was empty
grim star
what
modest pivot
what
jade pagoda
there was GRUB_CMDLINE_LINUX="" at first
modest pivot
Oh yeah, change that.
jade pagoda
its done
modest pivot
Run sudo update-grub and restart.
modest pivot
Maybe to see how things are also like, try booting to a live environment of Ubun...
If still no nada-nada batshit bullshit, see if this goes.
Didn't know Elan touchpads are this much of a pain.
grim star
yea I think its the driver
modest pivot
yea I think its the driver
They've got poor compatibility and support from what I've heard?
If so, I guess I'll have to add that to my horsemen of poor hardware compatibility on Linux.
- NoVideo
- Mediafuck
- Bruhcomm
- FakeTek
- Elanlanlan
jade pagoda
Run `sudo update-grub` and restart.
nope
grim star
They've got poor compatibility and support from what I've heard?
yea he might have to switch to some other distro. From what he got from the forum, it might not be supported anywhere
jade pagoda
damn
modest pivot
This is kinda sad, at least you got a mouse? And I've got my friend ghost/fellow human here.
jade pagoda
well i did find a forum page as a last resort but yea if that doesn't work i'll use another distro
says to install a patch
jade pagoda
hold on lemme translate what one of the users said
"Hello, i have the same laptop and a patch was published by a user on a forum to make the touchpad functional on linux"
"you need to edit your acpi tables so that the kernel recognizes the pad"
here's the patch they gave

grim star
idk if I would do that. It seems too complicated. You might mess up your firmware.
modest pivot
Same here, I could hardly understand it tbh
grim star
yea sadly
jade pagoda
damn
grim star
Or you can wait. Maybe someone else might be able to help you.
jade pagoda
so if im not mistaken "Xia" is the distro right
thats what my terminal says at least
jade pagoda
...ah
so i gotta stop using mint
i should probably mention it didn't work on arch either
sorry i forgot to say that
modest pivot
Yeah pal 
jade pagoda
so is the problem that it somehow doesnt work on both distros or is there something else going on
modest pivot
Though the mouse works, could be that Rigel really needs or want to use the touchpad
grim star

yea but if doesnt work on Arch, it probably might not work on any other distro.
jade pagoda
well i am using a usb mouse rn but its not that practical and its also the only one we have at home (i'll buy one sooner or later)
modest pivot
so is the problem that it somehow doesnt work on both distros or is there someth...
Basically, what it tells us is that:
- It won't even work in newer versions.
- Support is fucking spotty for Elan touchpads.
- We could probably wrestle with it, but it'd be a lengthy one.
modest pivot
Ubuntu Cinnamon 25.04 or Fedora Workstation or KDE
Thank goodness Marius, you're here 🙏
trail parrot
Let me look on that elan driver I have used years ago.
jade pagoda
huh, i was recommended fedora before
trail parrot
Don't think will work.
jade pagoda
dang
trail parrot
modest pivot
I hope this works 🙏
trail parrot
Open /etc/default/grub and add/modify: GRUB_CMDLINE_LINUX="i8042.nomux=1, i8042.reset".
trail parrot
Then save the file and run: sudo update-grub.
jade pagoda
just to make sure
did i do that right
also this is KILLING my battery holy shit
not related to touchpad but if y'all know a fix for that feel free to share
trail parrot
I think is correct. Let me double check.
modest pivot
Is there supposed to be a comma?
jade pagoda
lemme try without
trail parrot
Have you run sudo update-grub?
trail parrot
Is there supposed to be a comma?
I think yes.
trail parrot
Ok. Looked again. It seems you need to list them without comma: i8042.nomux=1 i8042.reset.
jade pagoda
yea i tried it that didnt work either
trail parrot
Try looking into journalctl -xb. There should be some line saying if the kernel recognizes the parameters or not. Let's see what it says.
Like a line starting with Unknown kernel command line parameters....
jade pagoda
rigel@mekane:~$ journalctl -xb | grep -i unknown
May 01 15:36:59 mekane kernel: Unknown kernel command line parameters "splash BOOT_IMAGE=/boot/vmlinuz-6.11.0-24-generic", will be passed to user space.
also unrelated but what does
May 01 15:37:01 mekane dbus-daemon[573]: dbus[573]: Unknown username "whoopsie" in message bus configuration file
May 01 15:37:01 mekane dbus-daemon[573]: dbus[573]: Unknown group "power" in message bus configuration file
mean
trail parrot
Not sure.
jade pagoda
who the fuck is whoopsie
trail parrot
who the fuck is whoopsie
getent passwd whoopsie to find out
However, please share this output: grep -i "Using input driver" /var/log/Xorg.0.log
jade pagoda
says absolutely nothing
rigel@mekane:~$ grep -i "Using input driver" /var/log/Xorg.0.log

Try to install this:sudo apt install xserver-xorg-input-synaptics
Log out and then log in.
trail parrot
Have you logged out and logged back in?
jade pagoda
yes
im gonna uninstall libinput to force it to switch to synaptic 
(just kidding)
(it did not go well last time)
trail parrot
I am very currious of 2 things:
- Do you have secure boot enabled:
mokutil --sb-stateshould tell us - Booting from the USB stick will your touchpad work?
jade pagoda
I am very currious of 2 things:
1. Do you have secure boot enabled: `mokutil --...
the answer to 2. is no sadly
secureboot is disable
d
someone online says that this can work
``Reboot, select the grub entry and press "e" to edit the kernel line. Where you see the word "quiet" add after i8042.nopnp=1 pci=nocrs. Press control+x to boot.
See if things work. If not, post the output of cat /proc/cmdline to check you entered the command properly.
``
trail parrot
Yes, but better do it from grub:
/etc/default/grub add/change: GRUB_CMDLINE_LINUX="i8042.nopnp=1 pci=nocrs"
Then run sudo update-grub and reboot.
Have you tried this?
jade pagoda
i did
didnt work sadly
also i tried to follow another tutorial to fix this and now my internet doesnt work
trail parrot
😦
jade pagoda
im supid
trail parrot
Do you have any timeshift snapshots to revert to?
jade pagoda
the guide in question was
https://gist.github.com/mgd722/436bf5d656f3005c40a9eef2d9c31fae
jade pagoda
Do you have any timeshift snapshots to revert to?
yea i think i do
i have one from 2°15' ago
2pm basically
ok im back
nothing during the last two hours happened :D
so uh everything that happened in that thread got retconned
trail parrot
I have seen that patch but I will not do that.
jade pagoda
oh
trail parrot
First, look in BIOS to make sure touchpad is enabled. Secondly try to look on the keyboard, there should be some buttons to toogle touchpad on/off. Maybe it is just turned off.
jade pagoda
yea on my keyboard its f6
it IS enabled
lemme look in bios again but i dont think theres any setting for the touchpad
my bios has stupidly few options
but the touchpad works in that menu
trail parrot
On Configuration tab there is something there?
jade pagoda
here's a list of all the options:
- system time
-system date - wireless LAN
- amd v™️ technology
- bios back flash
- hotkey mode
- fool proof fn ctrl
- always on usb
- charge in battery mode
- disable building-in battery
do you see any of these options that would hinder linux
trail parrot
hotkey mode? what does that do?
jade pagoda
[Enabled]
Use the hotkey function by pressing single Fx key. Use legacy Fx function by pressing Fn+Fx key.
[Disabled]
Use the hotkey function by pressing Fn+Fx key. Use legacy Fx function by pressing Fx key directly
also should i try disabling bios back flash
i dont trust it
trail parrot
Try disabling it.
jade pagoda
done
am i good to boot
maybe i should check the boot options
ive got usb boot, pxe boot tovlan and ivp4 pxe first
all enabled
trail parrot
Is ok. Nothing to worry there.
jade pagoda
ight
hmm
i never tried to boot with GRUB
what could possibly be in there
it just boots mint
trail parrot
Do you have dual boot there?
trail parrot
boot "Ubuntu".
jade pagoda
what wouldve happened if i didnt
also touchpad still doesnt work
le sigh
ig its not that big of a deal
ill buy another mouse like tommorow maybe
trail parrot
Better get a mouse. Sorry, except that ACPI patch(which I would not do) I have no other ideas.
