[Bug 1167869] Re: [keymap] Dell Latitude D830: hibernate key

[Martin Pitt]

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).

** Changed in: xkeyboard-config (Ubuntu)
       Status: New => Triaged

** Summary changed:

- [keymap] Dell  Latitude D830: hibernate key
+ KEY_SUSPEND should mean "hibernate"/XF86Hibernate

** Also affects: kde4libs (Ubuntu)

Bug description:
  
  <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.
