Public bug reported:
Suspend on lid close has been working fine for me up until some recent
(last month-ish) update. Now, when I close the lid, the screen goes
dark, but the suspend-light doesn't blink, and when I open it is not
locked and the laptop has obviously not suspended.
This is on a Thinkpad X200 with Xubuntu 14.04, using xscreensaver for
locking (had some trouble with light-locker). The xcfe power settings
are to lock and suspend on lid close (regardless of plugged-in/battery).
Manually doing alt-f2 and typing "xflock4" locks the screen as expected.
Manually doing "sudo pm-suspend" suspends the laptop as expected.
Manually clicking the xfce4 tray icon and clicking suspend also suspends
the laptop as expected.
Running "acpi_listen" and closing and opening the lid shows:
button/lid LID close
button/lid LID open
Running "while sleep 1; do cat /proc/acpi/button/lid/LID/state ;done" similarly
shows
state: open
state: closed
state: closed
state: open
xfce4-power-manager claims it can suspend and sees the lid:
$ LC_ALL=C xfce4-power-manager --dump # LC_ALL=C for English
