Bug#762676: gnome-shell: docking laptop or restarting Shell while docked sets backlight to off

Package: gnome-shell
Version: 3.14.0-1
Severity: normal
I have a Lenovo Thinkpad X220 laptop with Intel graphics, a docking station
and a DisplayPort-attached monitor, in this configuration:
/---------\
/-----+ monitor |
|X220 | |
\-----+---------/
The X220 is the primary monitor (with the menu bar), if that matters.
When I dock the X220 into the docking station or restart Shell with
Alt+F2, "r", the X220's backlight turns down to its lowest level, which
is unreadable. Workaround: turn it back up with the hotkey (Fn+Home).
When I experienced this when docking the laptop I thought it was more likely
to be a kernel or "plumbing" bug (systemd or udev or something), but I'm
filing it against gnome-shell for now, since I can also reproduce it with
Alt+F2, "r".
Any debugging advice?
