Lenovo Legion Y530 Linux issues and solutions for wifi and touchpad mostly (Debian & Ubuntu)

Intel i7-8750H nVidia GTX 1050 Ti

Summary of my findings (Please comment if you can get further than me) :

edit: 06/2019 guys in the comments have found workarounds and new solutions !

Most importantly : Lenovo refuses to provide any kind of support for their product on Linux, even though the computer is sold without an OS

Ubuntu 18.04

  • switch the BIOS to UEFI (and don't forget to create the EFI partition, ~256Mb)
  • the computer will randomly freezes, during the setup phase, or afterwards. Current theory is that switching from iGPU to dedicated GPU causes the computer to freeze/hang (cursor still moves, but nothing else).
  • the keyboard and trackppad are not usable during the setup, though afterwards they both work.
  • the graphics performance are good (until the computer feezes of course)

Debian 9.5 (stable)

  • Switch the bios to UEFI (don't use legacy, don't forget to create the EFI partition, ~256Mb)
  • It installs properly in command-line using the expert mode.
  • GNOME will start and work as expected
  • The graphics drivers used by defaults appears to be "nouveau", graphics performances are poor
  • Installing nvidia-driver thru apt will cause GDM to fail starting.
  • The keyboard works during the setup and afterwards too
  • The touchpad doesn't work at all
  • The wifi works after typing sudo modprobe -r ideapad_laptop or adding blacklist ideapad_laptop to /etc/modprobe.d/blacklist.conf otherwise
  • The function keys are enabled by default, so altering the volume requires using the Fn key, for example.

Debian buster

  • no issues ! Install Debian 9.5 stable, changes your /etc/apt/sources.list to buster then apt update && apt upgrade && apt dist-upgade).
  • [edit] actually two things : no keyboard backlight, you have to use the Fn key to change the volume/brightness
