After Upgrade to Ubuntu 22.04: Left Shift key not working, English keyboar layout

Question

After the upgrade from Ubuntu 20.04 to 22.04, the left shift key isn't shifting letter case anymore, but instead switching between input languages.

During the update, a popup window asked me for a key to switch between "native and latin input" and I thought this was referring to Pinyin/Latin input, so I set up the left shift key for that.

How can I reverse this?

I already looked in Settings > Keyboard > Keyboard Shortcuts and Settings > Languages to no avail.

In the Terminal, using xev -event keyboard shows some output when I press the the right shift key, but none for the left shift key.

Furthermore, I'm now not very sure what my actual input method is. In the Languages settings, I can select between ibus, fcitx4, and XIM, but this apparently doesn't change anything of the behavior as well.

Does this answer your question? How can I disable keyboard layout switching with both shift keys? I think it's basically the same problem, and the answer should apply to you too. — Gunnar Hjalmarsson, Aug 15 '22 at 22:33

I found this question that gave me the hint to reset the setting to its defaults via:

gsettings reset org.gnome.desktop.input-sources xkb-options

Before, the value of this key was ['grp:lshift_toggle', 'grp_led:scroll'] and afterwards [].

Please see the answer of the duplicate question, which includes another step which I think is necessary. – Gunnar Hjalmarsson Aug 15 '22 at 22:37
Thanks for the link! Without changing /etc/default/keyboard, the problem would probably re-occur after system boot. This is exactly my problem, but I'm just wondering, why this question didn't turned up in my research... – Green绿色 Aug 15 '22 at 23:01
Can't tell. But there are a lot of similar Ask Ubuntu questions. I happened to remember that particular one. – Gunnar Hjalmarsson Aug 15 '22 at 23:33
However, an issue remains: during boot, I have to enter a password to decrypt my disk. There, the left shift key still doesn't work. How can I configure that environment? – Green绿色 Aug 16 '22 at 01:07
That's above my head. I suggest that you ask a separate question about that. – Gunnar Hjalmarsson Aug 16 '22 at 01:13
Ok, thanks. I created another question and hope that doesn't get flagged as being too similar. – Green绿色 Aug 16 '22 at 02:53
