Unable to change brightness of Thinkpad X1 Extreme 4K using function keys
I disabled Secure Boot in BIOS and reinstalled Ubuntu 18.10. I followed the steps described in the following link to modify the grub. However, after executing sudo update-grub and rebooted the system, I still cannot change the brightness using the function keys.

@lovedrinking See thinkwiki for possible solutions - special keys and LCD Brightness. It should work if correctly set-up. But I think that it should work out-the-box. ThinkPads are linux-friendly.

How come? Is there a way to make the brightness keys work? I installed the latest Nvidia driver but it doesn’t help.

Any resolution? I've seen people mention that it works on PopOS!, which is an Ubuntu derivative, so I wonder why it doesn't work on Ubuntu.

I installed Ubuntu 18.10 and then installed the automatically suggested nVidia proprietary drivers usingubuntu-drivers autoinstallin recovery mode, and my brightness keys work fine. I also switched to LightDM instead of GDM3 but that was more because locking the screen was not working properly with GDM3, I think the brightness keys still worked. I also have the 4k screen.

with ubuntu 18.04 on the X1 extreme I installdsudo ubuntu-drivers autoinstallas mentioned by @Ibrahim and rebooted. (I noticed it was a little dim) The screen got brighter, but the function keys for brightness still don't work.

Ok, I've figured it out for me, at least with ubuntu 18.04 as of 2/11/2019.
Install ubuntu nvidia drivers:
# use auto-install (as mentioned by @Ibrahim)
sudo ubuntu-drivers autoinstall
Edit the
GRUB_CMDLINE_LINUX_DEFAULTentry in the/etc/default/grubto the following:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nvidia.NVreg_EnableBacklightHandler=1"
Update grub configuration after edit and save:
sudo update-grub
Reboot:
sudo reboot
