Does kernel parameter "i915.enable_dpcd_backlight=1" help?

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`.

What if acpi_backlight=vendor is removed? Is there any extension or script installed to handle the backlight?

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?

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.
