I have the same issue and Comment #18 has the solution: Whereas the "Linux console" keyboard mapping correctly maps Ctrl-Space to outputing \x00, the "Default (XFree 4)" keyboard mapping incorrectly maps it to no output.
I believe this is the bug, and the "Default (XFree 4)" keyboard mapping ought to map Ctrl-Space to outputing \x00 like the "Linux console" keyboard mapping does. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1515881 Title: Ctrl-Space no longer works To manage notifications about this bug go to: https://bugs.launchpad.net/kde-baseapps/+bug/1515881/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
