Hrm. That is interesting. A few questions I have then. - What happens if you set drm.i915.invert_brightness to -1 in kenv(1) or /boot/loader.conf? - What happens if you set drm.i915.invert_brightness to 1 in kenv(1) or /boot/loader.conf? - What version of graphics/libdrm do you have installed? Did you rebuild it after installing the new kernel? (This shouldn't be necessary, but I am trying to gather all details.) Let's start there and see if we can pin down a cause.
