I have a problem with my keyboard: the left Alt key is not working any more.
When I logged in into the Window manager, I can remap the key to caps lock key, and everything works fine.
I changed the password for my main user, but didn't take into account, that the encryption password for my home partition should be changed accordingly. So, I cannot log in.
I would like to use Ctrl+Alt+F1 to log into shell, but that is not possible because I am missing Alt key.
I have the root password, but I don't have USB booting drive. I also tried the on-site screen keyboard, but unfortunately on Ubuntu that one has no Alt key.
How can I change the Alt key in Grub?
