KEY_SUSPEND should mean "hibernate"/XF86Hibernate

[Gannet]

<Fn><F1>. Puts the computer into hibernate mode. Dell QuickSet is
required (see "DellTM QuickSet" on page 129). --- Info from Notebook technical documentation.

XEV output:

KeyRelease event, serial 40, synthetic NO, window 0x3e00001,
    root 0x103, subw 0x0, time 5090384, (164,-14), root:(166,44),
    state 0x0, keycode 213 (keysym 0x1008ffa7, XF86Suspend), same_screen YES,
    XLookupString gives 0 bytes:
    XFilterEvent returns: False

So, as we see, this combination generates XF86Suspend code, and it is not working for some reason (nothing`s happened when to press it). It must generate XF86Hibernate to work.

Can you please follow the steps in /usr/share/doc/udev/README.keymap.txt to check what the current scan code/keycode for that key is?

[Gannet (ken20001)]

sudo /lib/udev/keymap -i input/event3
Press ESC to finish, or Control-C if this device is not your primary keyboard
scan code: 0x8A key code: suspend

cat /sys/class/dmi/id/sys_vendor
Dell Inc.

cat /sys/class/dmi/id/product_name
Latitude D830

That seems right. Unfortunately the naming between the kernel, X.org, and other places is horribly inconsistent. The kernel knows KEY_SUSPEND, which means "hibernate" (suspend to disk), and KEY_SLEEP, which means "suspend to RAM".

I guess the reason for the key not doing anything is that hibernate is disabled by default in Ubuntu. If you want to re-enable it, you can do that in

  sudo gedit /var/lib/polkit-1/localauthority/10-vendor.d/com.ubuntu.desktop.pkla

and remove the "[Disable hibernate by default ...]" block (there is one for upower, and one for logind if you are running Ubuntu saucy already).

[Gannet (ken20001)]

I'm using Kubuntu 13.04. And I enabled Suspend-to-Disk several days ago already and it works fine through Kickoff menu. So, you meand, that when I remove from com.ubuntu.desktop.pkla file following blocks:

[Disable hibernate by default in upower]
Identity=unix-user:*
Action=org.freedesktop.upower.hibernate
ResultActive=no

[Disable hibernate by default in logind]
Identity=unix-user:*
Action=org.freedesktop.login1.hibernate
ResultActive=no

my Alt+F1 button will work fine ?

[Gannet (ken20001)]

Recently deleted all two those block, restarted my system and it didn't changed anything. Fn+F1 still not working ! But it must because it returns the code. Also when I try to apply alternative hotkey to enter hibernate mode through system settings, when I pressing Fn+F1 it shows Suspend instead of Hibernate as it is default in KDE. For some reason Suspend is not working and system needs Hibernate code to enter Suspend-to-Disk mode. The last, as I said earlier, is working throught Kickoff menu. Please, see screenshots.

Yes, it should.

Fn+F1 doesn't working

[Martin Pitt (pitti)]

The udev keymaps are correct. As I said, on the kernel level there is only KEY_SLEEP (suspend to RAM) and KEY_SUSPEND (suspend to disk, aka hibernate).

On the X.org level, /usr/share/X11/xkb/keycodes/evdev assigns <I150> to KEY_SLEEP and <I213> to KEY_SUSPEND. /usr/share/X11/xkb/symbols/inet then maps <I150> to XF86Sleep and <I213> to XF86Suspend, mirroring the evdev naming. There is also an entry

      key <I255> { [ XF86Hibernate ] }; // KEY_HIBERNATE

But this isn't defined in /usr/share/X11/xkb/keycodes/evdev. Per the "evdev code + 8" mapping, this would correspond to KEY_RFKILL and thus be wrong.

So there are two things which can happen here:

  * Change the xkb mapping of <I213> to XF86Hibernate. This seems to be what KDE expects, and GNOME gets along with it as well (it handles both XF86Hibernate and XF86Suspend).

  * Change KDE to accept XF86Suspend for hibernation as well, in addition to XF86Hibernate (which is never emitted right now).

[Martin Pitt (pitti)]

I don't know which particular part of KDE does power management, starting with kdelibs for now.

[Gannet (ken20001)]

Should I write the same report on bugs.kde.org ? Or what can I do else to help ?

That would be a good first step, as this affects all distributions.
KDE might want to add support for XF86Suspend.

Thanks!
