Due to recent commit a5b2781dcab2c77979a4b8adda781d2543580901 , I'm facing an issue where the backlight is dimmer than before in comparison to the backlight pre-commit on my Thinkpad W530. Downgrading to an older kernel version fixes the issue. I also realise that this recent commit replaces the intel_backlight folder in /sys/class/backlight with acpi_video0. It is also worth mentioning that I'm using Nouveau on my W530. Below are the screenshots highlighting the issue.
