I am altering the keyboard configuration in Ubuntu 20.10 via
gnome-tweaks
and then, in Keyboard and Mouse/Additional Layout Options I set Alt/Win key behavior to "ctrl is mapped to Win and the usual ctrl keys", since I'm using a the mac magic keyboard.
This choice however is reset each time I lock the screen, so I have to keep resetting it.
Is there a way to fix this?
System details:
This is a confirmed bug in mutter: https://bugs.launchpad.net/ubuntu/+source/mutter/+bug/1899206
A fix has been released for 20.04 so try upgrading and checking the version:
sudo apt-get upgrade mutter
mutter --version
Technically not the answer to your question because it does not fix "gnome-tweaks"...
but in a terminal try:
gsettings set org.gnome.libgnomekbd.keyboard options "['altwin\taltwin:ctrl_win']"
to try to fix the problem you're trying to remedy...
