Debian :: Power Button On Keyboard Not Functioning
Jun 27, 2015
I recently upgraded to Jessie and am using the LXDE desktop. I like using the keyboard power button to shutdown the system but it does not work. I looked at /etc/acpi and everything appears okay to my untrained eyes, but there is obviously something not working correctly. Do I need to edit some config file or install some code in order to use the power button for shutdown ? When I look at Services Settings I see that acpid power management is selected.

I have a Genius K627 Keyboard with Power, Sleep and Wake buttons. ACPI is unsupported on my computer, but it can turn off its power supply when the system halts (PM is ok). I would like to bind the Power key on the keyboard to execute the /sbin/halt command. What I already know is that I can specify an event in inittab (kbrequest) that would execute a command. What I don't know how I can make my system receive pressing Power button as a kbrequest. The scancodes of Power button on the keyboard (by showkey): 0x74 0xf4
This is the line I was talking about in my inittab:
Code:
ce:12345:kbrequest:/sbin/halt
I think I should edit /etc/console/boottime.kmap.gz but don't know how I could insert this scancode into it.

I use Squeeze with Xfce. My problem is that recently (after the xfce updates) the xfce power manager doesnt react to the power button - it is set to suspend. I dont have gnome-power manager or anything like it running.
If i reboot the computer, the power button will work but if i suspend and resume, it doesnt work again.
The computer is built on an Asus M3N78-VM mobo (2GB RAM/Athlon3200+ single core).
acpi_listen detects the button press.
Any thoughts?

My keyboard status lights (Caps Lock, Num Lock, Scroll Lock) are non-functioning when in an X environment. The lights turn on and off as would be expected at the terminal.
xset can turn on the scroll lock, but but not the Caps or Num Lock.
numlockx can toggle the Num Lock light.
The functions of the keys on the keyboards works normally, it's just the lights don't update accordingly.
I have already run dpkg -reconfigure keyboard-configuration to no avail. and this is the information that /etc/default/keyboard has about my keyboard
Code: Select all$ grep -vE "^#|^$" /etc/default/keyboard
XKBMODEL="pc105"
XKBLAYOUT="us"
XKBVARIANT=""
XKBOPTIONS=""
BACKSPACE="guess"
The keyboard itself is a Corsair K70, if that matters.

I have a new Thinkpad X1 Carbon (3rd) and i am very pleased with this machine so far.
Linux support is very good and i only have a few issues remaining.
I am running Debian Jessie and tried this with 2 kernels:
linux-3.16.7-ckt11-1
linux-4.0.4 (vanilla)
Main Problem at the time is really cannot get the power button to work.
thinkpad_acpi module is loaded.
I am not very familiar what possibilities are available to catch input devices. Some search in the internet brought me to the following commands. I tried evtest with no result
Code: Select allroot@x1carbon:~# evtest /dev/input/event3
Input driver version is 1.0.1
Input device ID: bus 0x19 vendor 0x0 product 0x1 version 0x0
Input device name: "Power Button"
Supported events:
Event type 0 (EV_SYN)
Event type 1 (EV_KEY)
Event code 116 (KEY_POWER)
Properties:
Testing ... (interrupt to exit)
I tried acpi_listen also with no result
What else could i try? All other keys like lid event and all fn keys work flawlessly.
Just learned that the event needs about 1 second of pressing time to trigger

I have an Asus EEE Box EB1012 running Debian Jessie (headless with no GUI installed).
I'm trying to get the power button on the front of the machine to put the computer in suspend.
If I run pm-suspend from the command line, it suspends correctly and also recovers correctly by pressing the hardware power button.
Originally, pressing the power button (while running) would shut the computer down.
The acpi power button event script was set to run the command "/sbin/shutdown -h -P now".
I changed it to "/usr/sbin/pm-suspend", and restarted the acpi service/rebooted the computer (I tried both), but the power button still cause the computer to shut down.
I also tried setting no action (empty string) for the power button event, but still the power button caused shutdown.
Is the acpi system getting bypassed somehow? Is there another system to configure instead?

I have a problem with the suspend button (fn+f5) on my hp pavilion dv2000 laptop. It is working but only after an intervention. So, every I boot up my system the short-cut/button is not functioning. In order to make it work I have to open the Power Management Preferences and close them. I don't even need to change anything there. Now the button will be working just fine until the next restart. It's pretty annoying to visit the Power Management after each restart, isn't it. Any ideas how could I fix this?

Yesterday something has happened with power supply, so 2 of 3 PCs has shut down. And now my debian pc doesn't respond to multimedia (volume to be precise) keys, leds also doesn't work. Other keys are fine. Tried xev, but it doesn't respond to multimedia keys either. I have dual boot with Win7 on this machine, and it works fine with multimedia keys.
I believe this is a clue:

Im Using FC14 and i like it so far. been trying around a bit and made searches for my problem but either im blind or im the only one with this problem (which i doubt) i have a problem of the keyboard "dying" on me mid using it. it doesnt seem to matter what im doing, it still goes dead on me sporadicly. ive tried changing to 4 different keyboards. PS2 and usb keyboards. but all 4 keeps sporadicly dying on me until i reboot and it works again until its dies.im wondering if the problem is in the hardware detection somewhere..if you need hardware information it would be nice if you posted commands so i understand what you need

I upgraded from 9.10 to 10.04. The Caps lock indicator on my keyboard is not working (always off). The Num lock indicator works fine. I have the same problem with other keyboards. The other keyboards work with Windows & DOS. This isn't a show-stopper, but I'd like to get it corrected as it's problematic when typing in passwords, etc. that have hidden fields.

Keyboard and sometimes mouse stops functioning whilst using oowriter - it only happens with writer. I lose control for up to 30 secs and then it comes back - but it keeps happening. This is on a 10.10 machine with standard install. I have changed keyboard from wireless to wired and back to wireless with new batteries. I have uninstalled Office, rebooted and re-installed but it is still happening on native odt docs. Is this a common recent issue?

I am COMPLETELY new to Linux.I started a computer class recently and I started teaching myself PERL.My teacher had mentioned to me that it's far better for some reasons (he did not elaborate) to write code in a Unix system. So I got Ubuntu 10.10.I installed it along side my windows 7.After I setup my windows (had to reformat the disk) I decided to boot up into Ubuntu to set that up. I installed the necessary drivers that it required, and the updates. I was asked to restart the system so I did so.
It did not even shut down or restart my system.I waited patiently 15 minutes...30 minutes 1 hour... until I finally decided to hit the reset button on my PC. Then when I'd boot back in to Ubuntu afterwards, it would stay at the log in screen and my mouse wouldn't budge and nor is my keyboard recognized by Ubuntu.Im really frustrated and I've been searching for answers for the whooole day and I just can't seem to find something well explained. Im completely new to Ubuntu so I don't know where to enter any code in a cmd line or such.
1)Reformatted my harddrive to install windows 7 on it
2)Set up windows 7 and then booted into Ubuntu.
3) Set up Ubuntu and installed necessary drivers and updates
4) Reset the computer and waited for an hour for the reset to happen but nothing happened.
5) Manually reset my pc and booted into ubuntu
6) Stuck at log in screen with mouse and keyboard not functioning (unable to use ubuntu).

I've got a F10 machine set up as a media center (with mythtv...mythdora to be precise) and I love that it's based on fedora since I'm most familiar with it..I would like to map the power button press to a command "pkill X" since sometimes the frontend freezes and running this command kills X (I'm running ratpoison for the speed and simplicity...it just gets the job done and doesn't get in the way).Any help in mapping a single button press to "pkill X" would be greatly appreciated. I also need some help adding this command to the sudo list so the regular "mythtv" user will be able to run it...no password can be entered since the machine has no keyboard. Currently I log in via ssh to get this done but it would be nice to not have to boot up a laptop just to do this.

We are planning the migration fro Karmic to Lucid for our systems, these systems are custom Ubuntu installations, we create them using debootstrap and then running a script that installs desired packages, mainly X server and (optionally) fluxbox.
I've set up a hard drive with our current scripts (the only modifications were the change of lucid instead of karmic for update servers and removing usplash from our scripts), but I've found that pushing the power button would not shut down the system (we have no GDM or similar), the system does not respond to this event as used to do under Karmic.
Do you know where I can check/enable the system to shutdown when pushing the power button?

Occasionally, the power off button on the panel goes missing on Ubuntu 10.10 installation. I can't seem to notice any pattern to it. I can shut down from the command line just fine, but how can I get the button back?

I built this small server for a coworker that by nature of its purpose will get turned off and on often. I want it setup so that he can just press the power button to have it power off normally. Normally I can set that up in Gnome, but in this case I don't want to install a GUI. Is there software that can tie the button and the the poweroff/shutdown cmd together without needing a desktop environment

I'm using Fedora 12 with LXDE (sudo yum groupinstall LXDE if you want to try it), and while using LXDE rather than GNOME, the power button doesn't do anything. I found a possible solution here: [URL] but I have no /etc/acpi/ folder. Why is that? Package acpid is needed.

In Ubuntu 10.04: if the screen has been locked (automatically by the screensaver or user-activated using the top-right menu) pressing the power button doesn't initiate shutdown. Is this a bug or is it a configurable option?I would expect to either get the usual 60 second shutdown delay or a graceful shutdown right away.

Recently i've switched from ubuntu 8.04 to Lubuntu 10.04, since that time the powerbutton does not work anymore.I've tried to find out how powermanagement is implemented in ubuntu to be able to debug this problem. But most documentation about this topic seems dated.I've already tried a few thing, most important stuff I did is:
- tested the scripts in /etc/acpi/ and added a line to write something to a textfile when its called. But this file is not called when pressing the powerbutton.
- checked bios settings, seems alright (and these settings worked on 8.04 to).

I've installed lucid on two computers now and have been using or a few months.Overall, it's pretty good and everything just works. However, every now and then (seemingly random), the power button in the indicator appletsion panel widget randomly disappears, so I'm unable to shut down my computer without re-adding the widget, or using the command line to shutdown the computer. Now this is acceptable for me, an advanced user. However, this is not acceptable for my parents and family, who also use ubuntu computers. Today, my mother called me to ask why she couldn't turn off her computer. I was dumbfounded, and had to walk her through turning it off "by hand."
Now this is not me accidentally removing the indicator applet session panel item. No, I can still see the user name bubble with availability information and I can still switch users. It's just that the power button is completely missing (sometimes the place where it used to be is occupied by a corrupt graphic). Additionally, if I login later, the power button magically returns without me having to do anything with regards to the panel. This is disappointing indeed.
Honestly, this is why ubuntu and linux in general still have the reputation they do of being non-user-friendly. At least in windows or mac, when I get fed-up I can turn it off. But not so in ubuntu. No ubuntu tortures me continuously and I marvel that such a simple thing has escaped the minds of such advanced programmers. I wish Canonical would focus on letting us TURN OFF the computer instead of adding crazy features that I'm not going to use. I mean how can a real operating system fail at such a simple task

I am building a small Ubuntu box made for our clients to listen to an audio stream. At startup, I have scripts that start the audio stream, then locks the screen so clients can't change any settings. It works flawlessly.
However, if a client has to shut down the box, they can't. Note this is a headless unit, no monitor, keyboard, or mouse. It will ONLY be used to play streaming audio. I need for the client to be able to safely shutdown the unit by pressing the power button. But, when the power button is pressed, ubuntu asks for the user password. Is there a way to just make the system shutdown without entering a password?

Is it possible to have the power button emulate the press of a key? On my media centre I have XBMC running and it doesn't recognise me pressing the power button. If I press S (on the keyboard) the shutdown menu pops up.

A friend of mine has an old emachines with XP on it and at first it would complain it had to test the disk and turn off in less then a minute. Now it won't do anything except run the power supply and cpu fans while the start button is pressed. I checked for power on the blue , purple ,red and orange wires while 14 and 15 were jumped on the power supply. There are no lEDs on the board and no beeps. I disconnected all the peripherals also
