Brightness control on the OLED version

OLED screens do not have a built in backlight, since they have their own light. Thus, they are usually controlled by PWM. Currently, a very small amount of OLED screens are supported by the kernel, and unfortunately, as of Sept. 2026, the X1 Yoga 1st Gen is not one of them. Currently, the workaround is to use some color filter on your screen, like on xorg: xrandr --brightness , this reduces available color information though.

There is a patch to support brightness control on the original OLED screen available at <https://chrisoft.org/blog/post/2025-04-28.html>. It has not been upstreamed yet, so using it requires building your own version of the i915 kernel module.
