Issues & Assistance

Hi Team, my laptops touchpad is not working after linux 6.16.7 update, I have been using Cachyos since last 5months, it worked fine till 6.16.6, and it working fine with linux-cachyos-lts kernel 6.12. Tested this twice even with fresh install.

Below is the output of “sudo dmesg | grep -i i2c“

[ 0.762597] ACPI: _SB_.PCI0.I2C0.PXTC: New power resource

I saw a similar touchpad issue with Arch Linux after updating mkinitcpio: block hook: mfd drivers break Lenovo IdeaPad touchpad (#295) · Issues · Arch Linux / Mkinitcpio / mkinitcpio · GitLab

I’m not sure if you are encountering the same issue, but I thought I’d post that link with my workaround in case it helps.

There are other recent reports about touchpad issues with Arch-based systems too:

@correctmost

Found similar issue threads

There is a patch added in 6.18, I haven’t tested it yet.

I have the same issue here with a Lenovo IdeaPad. The touch pad was working on/off until 6.18.0 and 6.12.60 finally broke it beyond my silly hacks (booting into hirens bootcd where the touchpad always works or powering down booting into 6.12.5x and then off and then back into 6.18-rc6).

Seems that even LTS kernels are of no help if backports end up breaking things…

And while setting `irqpoll` can make the touchpad work again, it also can cause the system to lockup before even reaching the graphical environment or, when it does boot okay, it will eventually lockup after a while during use. Not great.

@the-burrito-triangle

Yes, its not working in 6.18 also, for me its working in 6.12.60. I have raised an issue with Linux regressions(mail), please raise the issue from your side also.

I’d like to thank @correctmost for finding a work-around to this issue in #295.

Edit

usr/lib/initcpio/install/block

comment out

add_checked_modules '/drivers/mfd/'

then run

sudo mkinitcpio -P

and reboot.

Nice to have a working laptop again. When the touchpad broke (i2c_designware) it also prevented standby from working correctly (system would lockup when resuming from standby).

I tried to reflash cachyos with the latest iso and touchpad is not even working in the live usb with the latest iso (completed installation with the usb mouse), but its working fine with the previous iso.

@correctmost - Seems the issue is with the mkinitcpio only, as in the previous iso the version of mkinitcpio is below 40.

And its working fine after following your workaround. Thank you.

I’m glad the workaround helped.

I sent a report to the kernel regressions mailing list, so hopefully a patch can be developed: Making sure you're not a bot!
