After installing Mint 15 / updating to Mint 17, I'm unable to log in using the GUI login screen and German localisation with a password containing special characters. Changing the language using the language selector doesn't help.
It seems to be an issue regarding the window manager (mdm
), since I'm able to log in using a text console (e.g. using ALT+CTRL+F1).
Adapting the file /etc/default/keyboard
(as proposed on launchpad) or reconfiguring the keyboard configuration didn't change anything.
