I confirm this bug with the fresh and update stable Debian 10 (64bit) after installing Gnome. I cannot log in with keyboard in gdm3 because the ° character cannot be entered at all. I can log in only by showing the accessibility options, graphical keyboard on screen and picking this character from the list.
In regular GUI the Czech keyboard usually acts in such a way that to enter ° one must press SHift+; (left to "1" above Tab key) TWICE. In the console before I installed X and GNome logging in or entering sudo password was OK just pressing Shift+; once (no dead key behaviour). GDM3 if it uses keyboard with dead keys enabled it shhould allow entering ° character or similar dead-key characters the same way as for any other apps, = pressing the key combo twice. -- Martin Malec +420737740166 | brozkeff.net | martim.cz brozk...@gmail.com | mar...@protonmail.ch OpenPGP key ID: 0x1ADD5499
