I had a similar problem on my Lenovo laptop. When I opened the lid and
presumably waking up from a suspend, the screen would dim. I could brighten
it manually, but it was very annoying. I tried using xbacklight in
/etc/pm/sleep.d, but it had no effect. I did finally find a fix. I created
the file /etc/pm/sleep.d/01_backlight with this content:
#!/bin/sh
# Restore backlight setting after resume
case "$1" in
resume|thaw)
/bin/echo 15 >/sys/class/backlight/acpi_video0/brightness
;;
esac
Oddly, though 15 should be maximum brightness, it actually is a couple of
steps dimmer. But, it's much better than it was.
