There have been significant changes in Xorg and the handling of input devices. It is possible that through these changes things changed that affect your layout.
What I suggest, 'xmodmap' keyboard layouts are uncommon and show a degree of expertise in Xorg. In this respect, I suggest to take this issue to https://bugs.freedesktop.org/ and file a report them. You may also perform searches for existing reports on xmodmap there. I am closing this report as it did not have an update since 2008. ** Changed in: xkeyboard-config (Ubuntu) Status: Confirmed => Invalid -- xmodmap confuses keyboard layout in gnome https://bugs.launchpad.net/bugs/268967 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
