Did somebody try to install Ubuntu on Ryzen variant of Lenovo IdeaPad S340? I would like to try Lenovo IdeaPad S340-15API (81NC004VCK) but I worry that it will be useless on Linux.

  • Ubuntu 18.04 LTS derivative Linux Mint 19.1 is supposed to install on the L 340. https://forums.linuxmint.com/viewtopic.php?t=295978 I don't know but think the L series is for laptops with the Intel CPU and S series for those with the Ryzen CPU. Don't know what other differences might be. – user2182586 Oct 27 '19 at 08:37
  • "Duplicate"? Why? It is different HW. Compatibility is not problem of used CPU only. – user1009552 Oct 28 '19 at 21:26

Ok. I am try to test it. It looks, that it works fine.

  • Ubuntu 18.04LTS need update kernel (I am using 5.0.0, it is needed for graphic accelerator).
  • Ubuntu 19.10 works "out of the box".
  • MINT 19.2 is same as Ubuntu 18.04LTS

Here is ouput from "inxi -Fxzd" command:
