Hi,
I now i'm a little late but i didn't see this bug before.
I have a workaround for this bug.
open your text editor
code : gksudo gedit /etc/pm/sleep.d/04-backlight.sh for ubuntu
or kdesudo kate /etc/pm/sleep.d/04-backlight.sh for kubuntu
and paste this inside
#!/bin/bash
case $1 in
resume)
sleep 2
echo 1 > /sys/class/backlight/acpi_video0/brightness
;;
esac
Then save and make the script executable with sudo chmod +x
/etc/pm/sleep.d/04-backlight.sh in a terminal
The screen will not stay black anymore after suspend/resume cycle.
You can use also the fn+F9 keys to increase the brightness manualy if
the screen is black after a suspend resume cycle.
That's it.
