Driver issues on lenovo 9i. Nothing works.

**theogiroud** · January 8th, 2021

I installed ubuntu 18.04 LTS on new lenovo 9i yoga. Only the keyboard worked initially. Audio card and mic showed but were not working.

Adding few lines to /etc/modprobe.d/alsa-base/.conf fixed audio and mic.

The brightness controls are not working. Adding acpi_backlight=vendor to grub is the only option that gets the brightness bar visible but it still does not work. In case it helps, the grub setting also populates /sys/class/backlight/ with a folder "ideapad", which is not the case for any other argument like video, native, video0, or none.

The touchpad is not working. xserver-xorg-input-synaptics is installed. Grub has i8042.reset but it did not work. I am using an external mouse.

The touchscreen does not work either. I have no expectations from fingerprint since it is not on the supported devices list.

This is my lspci output:

I really looked forward to using this laptop since it has great specs but I dont know if the new tech is supported by ubuntu yet.

Suggestions to get anything working are very welcome. Thanks a lot!

If this hardware is very new, I would not expect 18.04 to have the necessary software in a default install as it is nearly 3 years old so have you run apt update && apt upgrade on it? You might have better luck with 20.04.

**theogiroud** · January 9th, 2021

Thanks yancek. I did run update and upgrade.
Actually, I installed 20.04 first but ran into the same issues which is why I though 18.04 might be better since there is more record for it. If nothing, I might upgrade to 20.04 again.

Special parameters in grub:

Code:

GRUB_CMDLINE_LINUX_DEFAULT="loglevel=3 apparmor=1 lsm=lockdown,yama,apparmor ipv
6.disable=1 quiet"

I have to admit, it wasn't the easiest install i've done.

**theogiroud** · January 10th, 2021

Thanks 1fallen.
However, adding the grub parameters do not change anything. Using only these parameters, the brightness bar disappears.
Apparently, only acpi_backlight=vendor gets the useless but visible brightness bar.

**theogiroud** · January 12th, 2021

I updated to 20.04 but having the same trouble.

**Yellow Pasque** · January 13th, 2021

Try a newer kernel. You can always boot back to the old one if things go wrong.

Code:

sudo apt-get install linux-generic-hwe-20.04

See if it works any better after running ^that command and rebooting.

**theogiroud** · January 13th, 2021

Things are working! Thanks a lot Yellow Pasque!

This fixed the brightness button but there was no control so I changed grub acpi_backlight to video. Brightness is working! I can now look at the screen without my eyes hurting.

My touch-pad also works now, though it lags a bit. The touchscreen is still not detecting my stylus. But I am happy it works like a normal, non-yoga laptop now.

Thanks a lot!
