I have found the reason for the "bug" in my machine. Somehow the slow keys feature of the keyboard was activated. I don't know how that happened, but that was the reason why disabling the a11y plugin did work around the problem. Sorry for the noise.
Maybe the rest of the people should recheck their keyboard accessibility settings. -- keyboard not working after logging in via gdm https://bugs.launchpad.net/bugs/59616 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is a bug contact for gnome-control-center in ubuntu. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
