Re: [Bug 1218322] Re: Can't set keyboard layout change to alt+shift, ctrl+shift, etc.
I think what is broken is just the program to configure these shortcuts.
Why? Because using workarounds I can configure my X to switch among layouts
when I press ALT+SHIFT. In my setup at least there is no inherent
limitation about the ability of using these special keys for switching.
To give an example of such a workaround in my Gnome Classic Flashback
(Metacity):
* If I right-click on the indicator icon, select "Text Entry Settings..."
then I will get a dialog window where I can define just shortcuts for
"Switch to next source using..." and "Switch to previous source using..."
and in this dialog box I CAN configure ALT+SHIFT. When I close the dialog
afterwards it works just fine, consistently, I can switch.
* In the "system settings" -> "keyboard" -> "shortcuts" dialog I can even
see ALT+SHIFT there, however if I delete this shortcut there is no way to
get it back in that dialog because it will not detect the key. I can always
set the shortcut using "Text Entry Settings".
Perhaps the problem is so trivial just for the case of Gnome Classic
Flashback (Metacity). But in Gnome Classic Flashback (Metacity) in my
opinion the only problem is the GUI in the system settings, and the problem
is that it does not detect the keypress. The dialog even displays this
shortcut correctly if it has been set using another tool, so the shortcut
storage and representation is working, just key press detection for setting
the shortcut is broken.

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The old PPA, ppa:attente/1218322 is superceded by the following one.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.

* 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.
