This seems to be related somehow; https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/1054034
I have experienced this on four of the computers I have upgraded to quantal. On all of them I had xflock4 mapped to Ctrl-Shift-L and rxvt to Ctrl-Shift-X. I cannot configure this behaviour on any of the computers. If I try to add a mapping as Ctrl-Shift-X it gets mapped as just Ctrl-X. As a stop-gap measure I have remapped to Ctrl-Alt-X, but this is awkward for me. I would really like to help in finding the source for this problem. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1055810 Title: Cannot create keyboard shortcuts To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xfce4-settings/+bug/1055810/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
