Question :

I would like to use a shortcut or any key to wake my computer from sleep mode using a Logitech wireless unifying keyboard (K800). I've already tried solutions from here and there.

Best case scenario, I would like the computer to wake only on keyboard events and not when the mouse linked to the same unifying device moves. But I'll take any valid solution that allows me to wake the laptop with one single shortcut or any key.

Best case scenario again, I would like to find a simple solution (not like this one)

Edit :

  • I just figured out that I can't even wake it with it's own internal keyboard (don't know if I messed up with some configuration trying to set up a workaround, or if it's always been the case.) So currently, only power button can wake that sleepy lazy laptop.
  • I've been through the same issue with all Ubuntu versions since 15.10, and still now on 17.04.

Solutions tried :

  • The solaar workaround answer on How do I get a wireless USB keyboard to to wake Ubuntu 13.10 from suspend? doesn't work.

  • That command have no impact on disable/enable status:

    sudo echo USB1 > /proc/acpi/wakeup

  • I've unsuccessfully tried to create wakeup files in, for instance (not sure to know where to put them):

    sudo echo enabled > /sys/bus/usb/devices/1-3.3/power/wakeup

  • I've unsuccessfully tried to add this in /etc/udev/rules.d/90-keyboardwakeup.rules

    SUBSYSTEM=="usb", ATTRS{idVendor}=="046d", ATTRS{idProduct}=="c52b" RUN+="/bin/sh -c 'echo enabled > /sys$env{DEVPATH}/../power/wakeup'"

Try the wakeup events like in this post into your BIOS! enter image description here

  • I don't have such option. I took some pictures of my BIOS menu if that could help. Regarding "USB" And "Wake Up" I only have "Wake On Lid Open: Enabled", "Legacy USB Support:Enabled", "XHCI Pre-Boot Mode:Auto" – mxdsp Jan 05 '16 at 14:13
  • My computer is a ASUS S550CM-CJ017H – mxdsp Jan 05 '16 at 14:15
  • just install the udev rule from this branch of solaar as described in the answer https://askubuntu.com/questions/440098/how-do-i-get-a-wireless-usb-keyboard-to-to-wake-ubuntu-13-10-from-suspend – user1514631 Oct 16 '16 at 13:00
  • @user1514631 I installed the udev rule and it still doesn't work. – mxdsp Mar 19 '17 at 14:45
  • @mxdsp make sure you really have the udevd rule in /etc/udev/rules.d/42-logitech-unify-permissions.rules installed and that your user is in the plugdev group – user1514631 Mar 21 '17 at 18:48
  • @user1514631 User is indeed in plugdev group and there is such a file, starting with # This rule was added by Solaar. – mxdsp Mar 21 '17 at 18:51

But I'll take any valid solution that allows me to wake the computer, with one single shortcut, or any key.

A non-logitech wireless keyboard or mouse should work. I had the same problem with Ubuntu Mate 16.04LTS on a Gibabyte MiniPC with Logitech devices.

But i can wake with wireless devices that are non-Logitech, non-unifying receiver like Nulaxy ML11 2.4GHz Wireless Mouse (confirmed working out of the box can wake Ubuntu) or for a keyboard the Azio Vision Backlit Wireless Keyboard (KB506W) Updated Version (haven't confirmed can wake) or this LotFancy 2.4G Wireless Mini Backlit Keyboard Mouse Touchpad Combo (confirmed working out of the box can wake Ubuntu)

I think that you are asking for a logical impossibility. Regardless of the configuration of the system, when the system is asleep, no software is running. Wakeups have to be triggered by hardware interrupt (wired keyboard, wired mouse, wired LAN). Your wireless keyboard cannot provide the needed hardware signal. The wireless keyboard is "connected" to your computer by a method that requires the computer to be "UP" (powered on, not asleep) to communicate.

  • I'm not sure if a made that clear that the computer is not powered OFF, just asleep. Are you saying that you can't wake a computer from suspend mode from an USB device (the Logitech unifying receiver, actually) ? Considering the readings I already made, I think there is a misunderstanding (I'm not native speaker). EDIT : Also, it seems to work just fine for Windows users. The unifying receiver is USB wired physically to the computer. – mxdsp Dec 05 '15 at 15:39
  • By "asleep" do you mean "screen locked, computer running", "hibernated" or "suspended"? – waltinator Dec 05 '15 at 15:57
  • Well, i'm not sure how to translate it, but I only have one button for "suspend" , different from "restart" and "shut down" in Ubuntu 15.10. I don't think that hibernation is active on system. I guess it's" suspended" then – mxdsp Dec 05 '15 at 16:07
  • In French we call that "mode veille" (sleep mode). It's not lock, not hibernate, not shut down. Should I replace "spleep mode" by "suspend" In the title ? – mxdsp Dec 05 '15 at 16:11
  • Here is a list of solutions/posts solving the same issue : 1, 2, 3, 4, as said in my question, i tried these unsuccessfully – mxdsp Dec 06 '15 at 18:25
  • logical impossibility? Disagree. windows can do that by default. The tone you say these words is vividly a slap on ubuntu-desktop's face. – funicorn Jan 08 '18 at 14:42
