@Markhor (markhor) and others.
Please specify Ubuntu version in your comments, do you have attente's ppas and do have enabled proposed updates. 

In Ubuntu Trusty 14.04 LTS, which we are waiting and testing, all common
hotkeys works as expected for now (see my table in comment #324 or test
it by yourself in Guest session or new user's session).

Bug description:
  ***
  The old PPA, ppa:attente/1218322 is superceded by the following one. You can remove the old repository using ppa-purge.
  ***

  A PPA which should provide some relief for this issue is available at
  https://launchpad.net/~attente/+archive/modifier-only-input-switch. To
  install:

  sudo add-apt-repository ppa:attente/modifier-only-input-switch
  sudo apt-get update
  sudo apt-get upgrade
  (log out, log in)

  If the packages improve the situation for you, you can pin them using:

  sudo apt-mark hold compiz
  sudo apt-mark hold gnome-settings-daemon
  sudo apt-mark hold unity

  If the packages don't work for you, you can purge them using:

  sudo ppa-purge ppa:attente/modifier-only-input-switch

  === compiz ===

  Impact: modifier-only key bindings need to be independent of key-press
  order, there's no support for double tapping two modifier keys of the
  same type

  Test case:
  - add at least two input sources through gnome-control-center's text entry settings
  - use gsettings to set the input switching shortcut to ctrl+left shift: gsettings set org.gnome.desktop.wm.keybindings switch-input-source "['<Primary>Shift_L']"
  - holding left shift, press and release ctrl
  -> the current input source should change

  Regression potential: possible, but highly unlikely, that some key
  bindings may be triggered due to the removal of some code that would
  normally prevent a possible tap from occurring.

  === unity ===

  Impact: gnome-settings-daemon eats modifier-only shortcuts preventing
  them from propagating down to applications

  Test case:
  - open gnome-control-center's text input settings
  - set the next input source key binding to ctrl+left shift
  - open gnome-terminal
  - press ctrl+shift+t
  -> gnome-terminal should open a new tab

  Regression potential: the additional input switch key bindings could
  collide with other functionality such as opening the dash or hud

  === gnome-control-center ===

  Impact: the UI to change the layout switching keys doesn't work

  Test case:
  - open gnome-control-center's text input settings
  - click on the "next layout key" entry
  - try entering a key combinaison (e.g ctrl-space)
  -> the UI should reflect the new keys

  Regression potential: that UI was not working before, it should only
  be an improvement (some key combos are not working as expected, that's
  another issue and shouldn't be mixed with this one)

  === gnome-settings-daemon ===

  Impact: attempting to change keyboard layouts using only modifier keys
  doesn't work

  Test case:
  - add at least two input sources through gnome-control-center's text entry settings
  - use gsettings to set the input switching shortcut to ctrl+left shift: gsettings set org.gnome.desktop.wm.keybindings switch-input-source "['<Primary>Shift_L']"
  - press and release ctrl+left shift
  -> the current input source should change

  Regression potential: The input switching shortcut might capture other
  non-modifier shortcuts, but users will need to consider this when
  choosing their switching shortcut anyways. For users this bug affects,
  this represents a working solution for a critical bug.

  Test results for different keyboard layout change hotkeys may be
  viewed and added in the Google Docs table, created by Norbert
  (https://docs.google.com/spreadsheet/ccc?key=0Ao5e713Ig9g_dEJrX2NRYlpLWWVzSWxsVXU4ck9HYVE&usp=sharing).

  ----------------------
  Recent discovered bugs related to keyboard layouts:
     * keyboard layout settings must be consistent between gnome-control-center keyboard, indicator-keyboard and gnome-tweak-tool and /etc/default/keyboard (bug 1270574)
     * Ubuntu 14.04 should have gnome-tweak-tool installed by default because of many settings that are missed gnome-control-center (bug 1270572)
    

  Separate bug reports for individual layout switching hotkey
  combinations:

  Super+Space and Shift+Super+Space:
     * Unity greeter (bug 1245137);
     * Unity session (bug 1245136);
     * lock screen - gnome-screensaver (bug 1245138, bug 1245256);
     * ubiquity installer (bug 1242572).

  Alt+Shift:
     * Unity greeter (bug 1245258)
     * Can't set keyboard layout change to Alt+Shift (bug 1245926)
     * Shift must be pressed pressed first (bug 1266179)

  Ctrl+Shift:
     * lock screen - gnome-screensaver (bug 1245270)
     * Unity greeter (bug 1245268)
     * Can't set keyboard layout change to Ctrl+Shift (bug 1245991)
     * If keyboard layout switching hotkey is set to Ctrl+Shift, Ctrl+Shift+C/V are not working in gnome-terminal (bug 1246656)

  Shift+Shift:
     * Can't set keyboard layout change to Shift+Shift (bug 1245272)
     * lock screen - gnome-screensaver (bug 1245278)

  Bugs which belong to keyboard layout switching:
     * Hotkeys not functional in non-latin keyboard layout in 13.10 (bug 1226962)
     * Keyboard Layout Options window is missed in gnome-control-center keyboard (bug 1245064)
     * Unable to set keyboard LED to show alternative layout in gnome-control-center keyboard in Saucy (bug 1245188)
     * Unable to set Miscellaneous compatibility options in gnome-control-center keyboard in Saucy (bug 1245199)
     * Keyboard shortcut for changing keyboard layout does not work on lock screen (bug 1244548)
     * [FFe] indicator-keyboard not working under greeter (bug 1228207)
     * Lost ability to remap Caps Lock to Ctrl (bug 1215826)
     * gnome-control-center keyboard no longer has way to modify caps lock key behavior (bug 1224575)
     * Pressing Caps Lock toggles LED even when mapped to another key (bug 1221403)
     * Switching layout turns off NumLock (bug 1247668)

  ----------------------

  Can't set keyboard layout change to ctrl+shift, Caps Lock, alt+shift
  etc. "Shift", "CapsLock" keys are just ignored in settings. Also the
  default shortcut was set to "Super+Space" that is inconveniently,
  because Dash is opening when you swich your keyboard layout.
