[Bug 451282] Re: display is fully dimmed after resume from suspend
Same problem with Kubuntu 14.04, on a HP 8530w, NVIDIA Quadro FX 770M,

display is fully dimmed after resume from suspend
Status in “linux” package in Ubuntu:
Binary package hint: gnome-power-manager
When I resume from suspend (while on AC power), the laptop display
brightness is set to it's lowest level, even when I had the brightness
turned all the way up before. Interestingly enough, this only seems to
happen on the first suspend after a reboot. Once I have turned up the
display brightness again using the function keys, the next
suspend/resume cycle will work normally (until the next reboot).
Finally, when I use the function keys to increase the brightness after
a suspend, I see that the brightness level in the notification bar
indicates that the brightness is set to the maximum. Only after
repeated adjustments with the function keys, the indicator 'resets'
and reflects the true display brightness level. I'm using the
proprietary nvidia display driver, but I've never had this problem
before in Jaunty. Also, in case it makes a difference, I've set my
laptop to suspend on lid closure since that's the way I generally
suspend the laptop.
