By the way, thanks to v66r for having inspiring me with the solution of changing kb layout to an alternative one.
In my case, there is no ill behavior left in the logon screen. In case it helps (but i'm not sure it can be compared to v66r german setting), my /etc/defauts/keboard reads like this : XKBMODEL="pc105" XKBLAYOUT="fr" XKBVARIANT="oss" XKBOPTIONS="" -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-input-evdev in Ubuntu. https://bugs.launchpad.net/bugs/993827 Title: Logitech Wireless keyboard has bad layout on login screen To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-input-evdev/+bug/993827/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
