[gpm] screen not locked after lid close and reopen

[Darren Hoo <darren hoo gmail com>]

Hello developers,

when I close the lid  the screen is not locked as I expect.while I
reopen the lid,the screen first gets blank and then unblank again.
My notebook itself can turn off the backlight upon lid-close without g-p-m.
but lock screen does work while resume from suspend or hibernate.

here's my setup:
/apps/gnome-power-manager/buttons/lid_ac nothing   nothing
/apps/gnome-power-manager/lock/use_screensaver_settings false
/apps/gnome-power-manager/lock/blank_screen true

the output of  gnome-power-manager --verbose is attached
when I close and reopen the lid,it seems that only  on-ac-changed
signal is triggered,never have I seen any lid button events.
what's wrong?

I have tried  version 2_26_3 and git master version.
