[Splitting this out from bug 267682]
On an Inspiron 1420 (and possibly other Dell models), the Standby key
(Fn+F1 in my case, with a little half-moon on it) does not trigger a
standby action (Hibernate or Sleep). From what I gather, it is supposed
to trigger hibernate.
Both hibernate and sleep actions *can* be triggered from the battery
icon, and will properly suspend and resume (although networking is lost
on resume from sleep, but that's a separate issue).
Running xev, the key is detected and forwarded up to Gnome by X, so I
believe X is doing whatever it's supposed to do. The output from xev
is:
KeyPress event, serial 33, synthetic NO, window 0x3800001,
root 0x7b, subw 0x0, time 7902503, (870,331), root:(876,404),
state 0x4, keycode 213 (keysym 0x1008ff10, XF86Standby), same_screen YES,
XLookupString gives 0 bytes:
XmbLookupString gives 0 bytes:
XFilterEvent returns: False
I can also hook XF86Standby to other Gnome actions, like launching the
help browser, using gnome-keybinding-properties, and it successfully
launches the help browser. So the key events are getting handled and
propagated. However, from what I understand, hooking the key to Suspend
in gnome-keybinding-properties is an obsolete way for setting this up.
Regardless, it doesn't work anyway; the event seems to get lost
somewhere in gdm and never runs the /usr/sbin/pm-suspend command that it
seems to be configured to trigger. Running that command from the
console does work at triggering sleep though.
I don't know if this is relevant, but I've tried viewing the contents of
/proc/acpi/events, however it doesn't let me read it as I think it
should:
~$ sudo cat /proc/acpi/event
[sudo] password for bryce:
cat: /proc/acpi/event: Device or resource busy
I'm not certain whether this is a kernel bug, acpi bug, hal, X, or...?
Near as I can tell it's not X, but who knows.
