Not sure if this is really a bug or a missing configuration on my side, so do not hesitate to re-tag my post.
I just finished a fresh new install of EOS. During the installation process, I set up my keyboard with french layout, and I could correctly enter a password with accents in it (like ¨).
Yet, when typing my password on the login screen (I installed Gnome desktop if that matters), I can’t get the corresponding key to work. The visual/virtual proposed keyboard (accessibility options) doesn’t provide the needed symbol.
Same result if I try on a TTY instead.
I didn’t get this issue with other Linux distributions (e.g. Ubuntu 20 or Debian 11).
What should work is use the USB installer and arch-chroot into the installed system. Then you can change the password temporarily and login normally and see if the locale and keymap is ok, or change the keymap.
The EndeavourOS wiki has articles about arch-chroot.
Looks like either some wayland setting is not fully correct, or wayland has a problem setting the keyboard layout.
AFAIK, Gnome is using Wayland by default. I’m not using Gnome, but I assume you can start an Xorg session instead of Wayland at login.
Not sure if this would help but try activating the on-screen keyboard on the Login screen and see if you can input those symbols. Click on the icon of the person on the bar and toggle on the on-screen keyboard.
I already tried that but the on-screen keyboard doesn’t provide this symbol. I’m confused why the keymap seems to be correct once the session is started, but not on login screen, for few symbols (I do have the french layout on login screen based on the position of other symbols).
Thank you for investigating this issue. Do you think it is worth trying to install another desktop manager such as xfce to see if this leads to a change ? Or it has nothing to do with this issue of “dead” key in the prompt of login screen ?
