I have successfully updated Ubuntu 18.04 to 20.04. While updating I was asked to set a keyboard shortcut to switch between Latin (not sure something like this) and US keyboard layout and I was unfortunately stupid enough to set it to Alt+Shift. Now I got problems because I would like to use this shortcut to start a smart column selection in the text editor (actually c++ programming). But anytime I press Shift+Alt the source language is switched instead. The Settings->Keyboards Shortcuts->Typing->"Switch to next input source" are set to Super+Space (no Alt+Shift at al) Also tried to disable this issue. No effect. This shortcut / setting seems to be hidden quite deep.

Many thanks for any good idea how to resolve it

Cheers

    What is your desktop environment? GNOME, KDE, whatever? What is the output of cat /etc/default/keyboard | grep XKBOPTIONS .

Reset to default

The options for toggling keyboard layout are those starting with grp: in man xkeyboard-config. You have chosen grp:alt_shift_toggle when configuring your system. To revert it to the defaults, simply delete that string from /etc/default/keyboard via text-editor. It may also be possible via dpkg-reconfigure keyboard-configuration. which is an interactive tool, but I'm not sure if it will ask about that option. Worth giving it a try.
