--- Comment #3 from Dan Robinson <dlrobin...@gmail.com> ---
Well remember how I said it wasn't happening?
Thanks to the magic of inotifywait, I just confirmed that I'm not crazy, and my
actual hardware backlight is flashing to full when I wake my display up to
reveal the lock screen.
It seems to only happen if I have "dim screen" set in the power saving settings
with the screen blanking afterwards. If I turn that option off and just have
the display turn off, it didn't happen.
If anyone wants to confirm that it's happening, here's what I did:
1. Set your lock screen time and dim screen time to 1 minute, set your display
off time to 2 minutes.
2. Open a terminal and (install inotify-tools if you haven't, then) run:
# inotifywait -m -e modify /sys/class/backlight/intel_backlight/brightness
| while read file event; do cat $file; done
(obviously if your backlight isn't intel, change that part)
3. Wait 2 minutes, then wiggle your mouse and unlock your screen
4. You should see a big string of numbers going from 0, then very high, and
then coming down to whatever your brightness was set to.
