Bug#410060: xkb-data: ctrl:swapcaps doesn't work (fully) correctly

[Peter Baumann <waste.manager@gmx.de>]

Package: xkb-data
Version: 0.9-4
Severity: normal

I'm having a strange problem concerning my keyboard setup.

Let me describe:

I have fvwm-crystal installed with 4 virtual desktops and setup a
mapping by <ALT>+<CTRL>+1 do move the active window onto the virtual
desktop 1 (of course, pressing <ALT>+<CTRL>+4 moves the window to
desktop 4).

If I setup my xkb config like this:

  $ setxkbmap -v
  Trying to build keymap using the following components:
  keycodes:   xfree86+aliases(qwerty)
  types:      complete
  compat:     complete
  symbols:    pc(pc105)+us
  geometry:   pc(pc105)

it works as expected. But as I like to have Caps_Lock as an additional
CTRL Key, I run

  $ setxkbmap -layout us -option ctrl:nocaps
  $ setxkbmap -v
  Trying to build keymap using the following components:
  keycodes:   xfree86+aliases(qwerty)
  types:      complete
  compat:     complete
  symbols:    pc(pc105)+us+ctrl(nocaps)
  geometry:   pc(pc105)

and now Caps_Lock behaves like CTRL. I can move my window to every
desktop *except* to desktop 1. That means pressing the keys
<Caps_Lock>+<ALT>+1 does nothing. But pressing <CTRL>+<ALT>+1 behaves as
it should. (so does <Caps_Lock>+<Alt>+2..4)


If I could do anything more specific to resolve this issue feel free to ask.

I don't now if it's usefull, but I attached the output of xev
pressing <CTRL>+<ALT>+1 because <Caps_Lock>+<ALT>+1 had _NO_ output.
