I bought Lenovo IdeaPad-5-15IIL05, installed elementary OS 5.1.5 Hera:

  1. No sound (no sound output device).
  2. The touchpad does not work.
  3. The brightness adjustment through FN does not work.
  4. alsamixer does not open, writes no directory

Please help with the solution of this issue.

Changed the core of i8042.reset quiet splash (sudo nano / etc / default / grub) - the result does not work.

Sound card:

Multimedia audio controller: Intel Corporation Device 34c8 (rev 30)
Subsystem: Lenovo Device 3841

I have the same issue. I have installed Hera on an Ideapad 100S-11IBY and there is no sound. The sound settings screen frist shows there is no audio device but in a few moments it switches to Atom Processor Z36xxx/Z37xxx Series Graphics & Display (???)

I have tried your solution, but I am getting the same error. additional note, even though I run command with sudo it does not ask for the password.

the issue of cp is the way you typed the source directory /firmware-linux... it is looking for it in the root directory instead of current folder. when I changed the line to this:

sudo cp -R firmware-linux/i915/* /lib/firmawere/i915

it ran correctly.

after the full process I have rebooted but I am still getting the No output device screen

Type in terminal:

sudo gedit /etc/default/grub

Change

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

to:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash snd_hda_intel.dmic_detect=0 psmouse.elantech_smbus=0"

And save the change. Exit gedit.

Then type:

sudo update-grub

and Reboot.

You can check if soundcards are detected with:

aplay -l

If you do not have gedit, you can use nano instead gedit.

If

psmouse.elantech_smbus=0

will not work, remove it and instead add this:

i8042.nomux=1 i8042.reset

  • I edited my answer above. Add psmouse.elantech_smbus=0 in /etc/default/grub and perform update-grub once again.

    Jun 21, 2020 at 17:42
  • Additionally you can check errors with touchpad in terminal : sudo dmesg | grep -i elantech.

  • Did you try psmouse.elantech_smbus=0 instead of i8042.reset i8042.nomux i8042.nopnp i8042.noloop? I mean remove i8042.reset i8042.nomux i8042.nopnp i8042.noloop and add psmouse.elantech_smbus=0

psmouse.elantech_smbus=0 - this option does not work

i8042.nomux=1 i8042.reset - this option does not work

sudo dmesg | grep -i elantech - does not execute a command

Try this solution:

1. cd /home/yourusername/Downloads/

2. mkdir i915

3. cd /i915/

4. git clone https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git

5. sudo cp -R ./linux-firmware/i915/* /lib/firmware/i915/

6. sudo update-initramfs -u

It was made a corection in line 5.

  • Can you perform each command separately exactly the way I described one by one? You are doing it wrong. I provided the instruction how it should be done correctly. Do not try to make it in a different way, please.

I got the answer from this post.

https://askubuntu.com/questions/1227972/touchpad-of-lenovo-ideapad-s145-15iil-not-detected-in-18-04-and-19-10-ubuntu-an

The workaround is to pass these parameters to the kernel.

i8042.nopnp=1 pci=nocrs

It's recommended to test before change definitily like this.

https://wiki.ubuntu.com/Kernel/KernelBootParameters

This worked for me.
