I have been trying Manjaro for the past month, coming from Ubuntu for the last 8 years, and this is the last issue that is really bugging me.
So, I have a '^' in a password I use on my system, and I'm using an azerty keyboard (because I'm french), and on every other Linux system I have used, (Debian, Ubuntu, OpenSuse), spanning multiple devices, it as never been an issue.
But on Manjaro, which I only have tried on one of my desktop computer for now, most of the password fields don't support it.
Normally, this key is used to compose other special letter, like ê, â, î and ô. The way you use it is by pressing it (^), then after releasing it, pressing the letter you want. If you just want the character ^ itself, you have to press the key twice.
This works everywhere on the system, in fact I can use it right now to type this message, but on some password prompt, this character can't be inserted by pressing the key twice. The only way I have is by copy-pasting, or virtual keyboard when it's available.
I first tried Manjaro KDE, but decided to go back to Gnome today. The issue affect both system, but not in the same places.
On KDE, I cannot use it to unlock the lockscreen (but can use it to login), and on graphical password prompt, like when launching gparted.
On gnome, I cannot use it on login, lockscreen, and any GUI password prompt.
This does work on terminals (tested with
read -s password; echo $password), or when I use a qwerty keyboard.
My google fu has been useless on this one, so if anyone here as any idea on how to attack this problem I'm listening.
PS : the console also as a different issue with this character : when a press the key, the character ^ is inserted right away, preventing me from using the special letter ê, â etc. in the console.
