Installation problems on Lenovo V15 with AMD Ryzen 5 7520U

English Install/Boot/Login

Hello.

I am trying to install openSUSE Leap 15.5 on a new Lenovo V15 with AMD Ryzen 5 7520U. The keyboard and mousepad on this model are not working with Linux, and I get stuck already on the first screen of the installation without being able to do anything. I can get around the issue by connecting and external mouse and keyboard, but will not proceed with the installation if such basic problems already show up.

I tried many other Linux distributions, and in all of them I encounter the same problem (with the exception of the latest Kubuntu - however it’s also not a good solution because there are serious power management problems with that OS). How can such basic things not work with the recent Linuxes? What should I do to further troubleshoot and solve this issue?

Thanks a lot in advance,
Udi.

Try a Tumbleweed live iso. If it works with that, then one solution would be to install Tumbleweed. Or use your external mouse and keyboard to install Leap 15.5, but then install a newer kernel from:

http://download.opensuse.org/repositories/Kernel:/stable:/Backport/standard/

If Tumbleweed works for your hardware, it is very likely that the newer kernel will also support that hardware.

go on the Lenovo website and download the latest BIOS, if your machine has “touched” Windows 11 for just a few seconds your pointing devices have been killed by a bug.

Tumbleweed also doesn’t work with my hardware, but I am willing to try to install Leap and then upgrade the kernel. I see a lot of packages under the url you provided - which is the one I should choose? And do I just install it like a regular rpm or are there further steps?

If Tumbleweed doesn’t work, then upgrading the kernel probably won’t help.

When I use that repo, I just add that as an additional repo and install a kernel using Yast software manager (the “Versions” tab to select which kernel). However, it probably isn’t worth your effort to try this. Maybe try updating the BIOS as suggested by @LaloKP

Thanks, nrickert and LaloKP.

Just to conclude:

  1. The BIOS upgrade didn’t help to solve the problem (and I made sure not to let Windows boot up again so it won’t “touch” anything).
  2. I installed Leap anyways and installed the newest kernel (with a simple rpm command). I knew it’s probably hopeless and indeed the hardware is still not working.

I am currently using the laptop as a desktop with the external keyboard and mouse. Hopefully a real solution will be found someday soon, but for now that’s the only way for me to use Linux.

Thanks for the update.

I have the same laptop. It worked fine for a long time with every Linux distro I tried on it.
Back in April I needed to put a Windows 11 partition to help a friend with something. As soon as the machine connected to the internet a Windows update disabled the touchpad.
No matter what I tried from that moment on it also stopped working under Linux.
Everybody told me that the hardware would break sooner or later and it was just a coincidence.
Strangely enough, it also happened to other people with the same laptop, and a month later Lenovo released the May BIOS update and everything started working again.
Needless to say, I felt vindicated. I’m sorry this didn’t help you but your story was too similar to mine, it was worth a try.
