Bugzilla – Bug 1213771
Touchpad randomly stops working on Lenovo IdeaPad 5 14ALC05
Last modified: 2023-08-07 10:51:40 UTC
Created attachment 868493 [details] dmesg When using my laptop, sometimes the touchpad randomly stops working with apparently no reason, restarting drivers doesn't work, it seems that's something related to amd power management, switchet also to vanilla kernel but anything changed.

Do not touch the priority field unless you are a developer.
Is this a regression from the earlier kernels? In anyway, please give the hwinfo and the full output of dmesg. Also, if you see the broken state, please give the same outputs for comparison, too.

I have this problem since my first Linux install with another distro in this laptop (Kernel 5.4) and it still persists. It seems that in Manjaro Linux they have solved the problem somehow. Here in the attachments the dmesg and hwinfo outputs when the touchpad is working normally
Created attachment 868508 [details] complete dmesg output when touchpad is working properly
Created attachment 868509 [details] hwinfo output when the touchpad is working properly

Unfortunately I don't have any detail. It simply worked out of the box, maybe they have a modified kernel. When I first installed Manjaro I thought that the touchpad was working because they have a more recent kernel and the bug was fixed with Linux 6, but when I tried fedora 36 and now opensuse tumbleweed I noticed that the issue it's still here.
OK, then at least could you tell me which Manjaro kernel version / package, so that we can take a bit look?

It should be kernel 6.2 and above but I'm not really sure, I'm really sorry, wold like to help but I don't know how to know from which kernel version it started to work

OK, then at best, please report this to the upstream. But it's a bit difficult to tackle, as we don't know exactly which component triggers the problem. But, as it's an input problem, I'd begin with the input subsystem.
