I've just noticed an interesting quirk to this bug; the Caps Lock modifier key does work for the first character on the first attempt.
That is to say open login screen (by space bar if not already open), press and release Caps Lock, Caps Lock light now on, very first character to be typed is now modified to upper case. Caps Lock may then be turned off. I wondered why this one modifier does work, and thought that the modifier key being released before typing the character to be modified might be significant. So I tried pressing and releasing the normal shift key before pressing and holding it to modify the first character of the password. This also worked for me. (It is a little fiddly, so perhaps others might like to try to confirm that I'm not mistaken?) So, at the login screen, with the password box open but nothing typed yet, press and release the (right in my test) shift key, then press and hold that shift key while typing the first character of the password. I believe that this will give correct modifier action for the shift key. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1765261 Title: [regression] Ubuntu 18.04 login screen rejects a valid password on first attempt.
