Keyboard mapping issues

zanfix commented 1 year ago

Hi,

I am having some issues with keyboard mapping (Swiss German keyboard layout, qwertz)

With termux-x11 option "prefer scancodes" turned off:

the key ^ and ¨ will crash termux-x11 ^ key is between ' and backspace (the last key before backspace on the numbers row) " key is between è and Enter (the last key before Enter key on the "qwertz" row)
AltGr + < outputs ˛ instead of backslash < key is between Shift_L and Y

EDIT: - CTRL + z outputs CTRL + y, and CTRL + y outputs CTRL + z

With termux-x11 option "prefer scancodes" turned on:

the key between Shift_L and Y outputs `` instead of<`
AltGr + < outputs ˛ instead of backslash

For the AltGr + < one, here is the xev output:

@zanfix can you please check if it works?

zanfix commented 1 year ago

I tried build 384 but nothing changed!

zanfix commented 1 year ago

I had a look at logcat and:

With termux-x11 option "prefer scancodes" turned off:

AltGr + < logs only "ViewPostIme key 0/1" messages, no text event is shown

With termux-x11 option "prefer scancodes" turned on:

Every pressed key logs only "ViewPostIme key 0/1" messages

also TERMUX_X11_DEBUG=1 will segfault the loader immediately

EDIT: i also noticed that del key does not work, The following message is printed on logcat: "The input has been finished in ImeInputStage" when pressed. Does not happen with build 371

Unfortunately Android does not let applications detect AltGr. Maybe I can make an option to generate TextEvents with right Alt key, but in this case key combinations with right Alt will stop working.

zanfix commented 1 year ago

On my keyboard all other combinations with AltGr already work fine. it's only the key I mentioned that do not work:

AltGr + < outputs ˛ instead of backslash < key is between Shift_L and Y

twaik commented 1 year ago

I am not sure I can fix this. With my keyboard AltGr + < produces × sign with both setxkbmap de and setxkbmap ch -variant de.

It looks like KeyEvents sent by Android are IME-dependent or device-dependent. For some reason Android sends combined KeyEvents even in the case if it is not needed (at least for de_CH layout). There is no workaround for this.
