power button not bringing up shutdown dialog [karmic]

[Alexey Kotlyarov]

On Acer Aspire One A110L, pressing power button does nothing whatsoever. Worked fine in Jaunty. Also, acpi_listen outputs
button/power PWRF 00000080 00000006
on its press, and gnome settings say "ask for action" on power button. Ctrl-Alt-Del brings up shutdown dialog just fine.

I believe this is the correct package.

$ acpi_listen
button/power PWRF 00000080 00000009

is what appears when I hit the power button.

As discussed on #ubntu-devel, this is most likely because your power button still produces HAL events and gnome-power-manager is now built without "--enable-legacy-buttons", so it ignores these.

[Martin Pitt (pitti)]

Richard,

I had a look at this problem. It seems that the kernel side is alright, I get KEY_POWER input events:

$ sudo input-events 1
/dev/input/event1
   bustype : BUS_HOST
   vendor : 0x0
   product : 0x1
   version : 0
   name : "Power Button"
   phys : "PNP0C0C/button/input0"
   bits ev : EV_SYN EV_KEY

waiting for events
11:17:05.881107: EV_KEY KEY_POWER (0x74) pressed

However, they never make it through X.org, with xev I don't get XF86XK_PowerOff. g-p-m doesn't directly listen to input events, just to X.org key presses. So am I right in assuming that we need to fix the xorg driver to propagate KEY_POWER -> XF86XK_PowerOff, or is it meant to work in a different way?

Thank you!

I'm seeing this bug after moving from Alpha1 to Alpha2 on my Thinkpad X301.

[Dave Stroud (bigdavesr)]

I am seeing thos on my deskto pc also after alpha 2.

[Martin Pitt (pitti)]

Ah, it's a bug in hal, it doesn't mark the Power button device for -evdev.

[Steve Langasek (vorlon)]

According to the bug log, I believe the Thinkpads have a different bug. I don't see any keypress event when listening on the "Power Button" input device on my T60.

This looks like a kernel issue then, it doesn't convert the ACPI event
into an input event? Weird, though, I had expected that most of these
issues were fixed by now, especially with highly prominent laptops
like Thinkpads. Is this not covered by acpi-support either, or do you
have that purged?

[Launchpad Janitor (janitor)]

This bug was fixed in the package hal - 0.5.12+git20090626-0ubuntu1

---------------
hal (0.5.12+git20090626-0ubuntu1) karmic; urgency=low

  * New upstream git snapshot:
    - Add input.keys capability to power/hibernate/etc. keys. (LP: #384890)
  * Drop 01_tablet_evdev.patch, 50_no_crash_on_md_blockdev.patch: Applied
    upstream.
  * 04_nvidia_brightness.patch: Update to new upstream version.
  * debian/control: Change back Vcs-Bzr:, Ubuntu package are only for full
    source trees.

Not sure if I should open a new bug report, but the power button doesn't work for me...

OS: Ubuntu 9.10 64bit, upgraded from 9.04
Machine: MacBook Pro 3.1

Pressing the power button does nothing, instead of bringing up the shutdown dialogue like in Jaunty.

xev recognises it, so it might be just the applet not grabbing the event...
xev output:

KeyPress event, serial 38, synthetic NO, window 0x2400001,
    root 0x13c, subw 0x2400002, time 10331282, (43,42), root:(1273,95),
    state 0x0, keycode 124 (keysym 0x1008ff2a, XF86PowerOff), same_screen YES,
    XLookupString gives 0 bytes:
    XmbLookupString gives 0 bytes:
    XFilterEvent returns: False

KeyRelease event, serial 38, synthetic NO, window 0x2400001,
    root 0x13c, subw 0x2400002, time 10331282, (43,42), root:(1273,95),
    state 0x0, keycode 124 (keysym 0x1008ff2a, XF86PowerOff), same_screen YES,
    XLookupString gives 0 bytes:
    XFilterEvent returns: False

acpi_listen output looks fine:
button/power PWRF 00000080 00000008
button/power PWRF 00000080 00000009
...

The power button also doesn't work on a ThinkPad x200, but I can't provide xev (or any other) output for that machine right now. Although in that case, it might be the ThinkPad-specific bug...

> Not sure if I should open a new bug report

Yes, you should. The bug present in hal has been fixed; other kernel issues that prevent this button from working on particular hardware will need to be dealt with individually in the kernel.

[Robbie Williamson (robbiew)]

How long are you holding the button down for? It takes about a second or two for me before the dialog shows up.

[Donjan Rodic (bryonak)]

I worked around by assigning the XF86PowerOff keysym to Gnome's "Log out" shortcut.

@Steve: will do next time :)
@Robbie: depending on system load/state, it takes between 0.1 (almost instant) and ~1 second for me. But I don't need to hold it down, a short tap suffices.
