Touch pad recognised but can't be used

Issues & Assistance
1

Trying to follow the forum guide but also writing this on my phone so apologies if I miss anything or its not quite 1 for 1.

Lenovo Yoga Slim 7

Unlocked Bios with S3 enabled

6 core AMD Ryzen 5 4500U Zen 2
Full AMD retpoline

Downloaded the iso went to install no touch pad. Thought maybe it was a bad iso

Searched saw someone with a Toshiba saying edit a conf file and another say they had a Lenovo and it was fine.

Redownloaded iso as a torrent formatted the usb before using Etcher and flashed.

Boot all looks OK still no touch pad :thinking:

Libinput list-devices

Elan touchpad
Kernel /dev/input/events
Group 8
Seat 0 default
Size 104x61
Capability pointer gesture

Tap and drag enabled all other options disabled
Calibration n/a
Accel profile flat adaptive
Scroll method and click method both correct

What is stopping it from working ?

Ubuntu, Debian, Fedora, OpenSuse all worked out of the box.

Would really like to try this distro but I Sort of need the touchpad.

Still trying to find my feet with Linux but thought this project looked amazing thanks for any help you can provide.

Welcome :slight_smile:

Search your model, maybe you must downgrade your BIOS.

Thank you for your reply

Yes I did see that but that is for the pro model mine is the model above in that list, the ryzen 5 model not ryzen 7. The post suggests everything should be fine apart from the suspend issue but I have fixed that by enabling s3.

Any thoughts as to what could be the cause? If I boot straight back into fedora 34 everything is fine

If there are any commands I can run that would provide more detail to help I can do that too I'm just unsure where to look.

If you include terminal outputs in your post please use the proper output format in your post. Using "~" 3 times above and "~" 3 times below the text block will provide a readable, raw look.

Please edit your post. :slight_smile:

Please try with this blacklist

Thanks but I'm not sure how to do that from the terminal.

I rebooted into my fedora install loaded garuda in a VM and the touchpad works perfectly while in the VM which seems odd. Same ISO just one is flashed on a USB the other in a VM

For the 3 steps in the linked thread, use

sudo micro /etc/modprobe.d/blacklist.conf

This will create/edit the file, so that you can enter there blacklist elan_i2c, save, exit, reboot.

Ok will give it a go now and let you know if it works :slight_smile:

No change sorry issue is still present :upside_down_face: would appear even a noob friendly arch can still be tricky :rofl:

Sorry, the Arch wiki rarely fails.
And misteriously for this user the blacklist seems to have worked

Maybe you could check this arch forum thread. It is not solved, but seems to work with X (you don’t have wayland). Not clear to me which one of the two suggestions…
https://bbs.archlinux.org/viewtopic.php?id=267809
Finally you could try different kernels.
The newer the better probably in these cases.
I’d say linux-mainline or even linux-next
You can do this with the Garuda assistant.
No other ideas… :pensive:

It is a brand new laptop and I think the guys are catching up squishing bugs even in linux-next for the majority of the AMD-powered laptops at the moment. Probably just keep the image as a VM rotation and wait for a few updates, then when most current issues are resolved look at switching again but for now, the current distro is rock solid. Love the work though and even in the VM, it is the best-looking distro out currently with the most baked-in functionality I've seen.
