[ltp] Prevent brightness change for AC events

I never understood why anyone wants their laptop to change screen
brightness an AC plugging anyway, but my system's current behaviour is
just mad: whenever I either plug or unplug the AC adapter, the screen
changes to full brightness. Pressing Fn+F5 or fn+F6 immediately returns
to the previous state plus or minus one step.
Does anybody have an idea where I can disable screen brightness changes
for AC events?
- X240 w/ full HD IPS panel
- running Debian sid amd64
- "Desktop": awesome window manager with a few added programs that I
start in ~/.xsession:
- xset +dpms
- xset dpms 0 0 300
+ a few unrelated programs
I didn't find a setting that may be responsible for this behavior in
either xfce4-power-manager or gnome-control-center. I have
laptop-mode-tools installed as well but use CONTROL_BRIGHTNESS=3D0 in
/etc/laptop-mode/conf.d/lcd-brightness.conf. I also took a look into
/etc/acpi but didn't find anything relevant.
What did I miss?
I wear a lot of leather but would never wear fur.
