[Bug 1218322] Re: Can't set keyboard layout change to alt+shift, ctrl+shift, etc.

 

** Description changed:

- ***
- The old PPA, ppa:attente/1218322 is superceded by the following one. You can remove the old repository using ppa-purge.
- ***
+ [Impact]
  
- A PPA which should provide some relief for this issue is available at
- https://launchpad.net/~attente/+archive/modifier-only-input-switch. To
- install:
+ Can't set keyboard layout change to ctrl+shift, Caps Lock, alt+shift
+ etc. "Shift", "CapsLock" keys are just ignored in settings.
  
- sudo add-apt-repository ppa:attente/modifier-only-input-switch
- sudo apt-get update
- sudo apt-get upgrade
- (log out, log in)
+ [Test Case]
  
- 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)
+ - try entering a combination of two modifier keys such as Ctrl+Shift
  -> 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.

-    * Binding ctrl+shift, alt+shift, etc for switching keyboard layout makes shortcuts with ctrl+shift, etc not working in any program (bug 1245473)
- 
  ----------------------
- 
- 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.

Bug description:
  [Impact]

  Can't set keyboard layout change to ctrl+shift, Caps Lock, alt+shift
  etc. "Shift", "CapsLock" keys are just ignored in settings.

  [Test Case]

  - open gnome-control-center's text input settings
  - click on the "next layout key" entry
  - try entering a combination of two modifier keys such as Ctrl+Shift
  -> the UI should reflect the new keys

  - add at least two input sources through gnome-control-center's text entry settings
  - press and release ctrl+left shift
  -> the current input source should change

  [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)

  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.
