I installed from the .deb files and this did not make a difference for the backlight, however the volume keys on the keyboard no longer work. I am not experienced in testing different kernels so it is possible that I messed up the install. I did not apply the .patch files.

Re: [Kernel-packages] [Bug 1860303] Re: Backlight brightness cannot be adjusted using keys
There are no extensions or scripts that I have installed to handle the backlight. I did not include acpi_backlight=vendor as a kernel parameter at the same time as i915.enable_dpcd_backlight=1. The only kernel parameters currently are "i915.enable_dpcd_backlight=1 quiet splash". Should I try both backlight parameters at the same time?

Re: [Kernel-packages] [Bug 1860303] Re: Backlight brightness cannot be adjusted using keys
This kernel parameter does make the backlight respond to keyboard input, as well as manually changing the brightness values in `/sys/class/backlight/intel_backlight/brightness`. However the behavior is odd. Adjusting the brightness using the keyboard results in erratic changes rather than a smooth change in brightness. The brightness settings appear to range between 655 and 65535 in `/sys/class/backlight/intel_backlight/brightness` when using the keyboard keys. However, the max screen brightness appears to be at 2047 when manually setting a brightness value in `/sys/class/backlight/intel_backlight/brightness`.
