Up until this week I was able to dim my laptop to a very dim setting, barely any brightness at all, which I liked at night. After upgrading to 15.04, the maximum dim is way brighter than it was before. I lost my ultra-dim capabilities. What happened, and how can I get my ultra-dim options back?

Try editing this file:

sudo nano /sys/class/backlight/acpi_video0/brightness

May be elsewhere under /sys/class/backlight/*/brightness

source: Set brightness lower

EDIT:

Try reducing the gamma with redshift:

Reducing Contrast
