FWIW, I'm seeing the same thing with XFCE as the desktop. There's an upstream bug that may or may not be relevant: https://bugzilla.gnome.org/show_bug.cgi?id=661915
That bug relates to X Input Method (I didn't enable that, but I don't know if the latest Ubuntu update did, and I don't know how to check). Even if X Input Method isn't involved, the symptoms are similar enough that maybe there's some common cause. ** Bug watch added: GNOME Bug Tracker #661915 https://bugzilla.gnome.org/show_bug.cgi?id=661915 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1306500 Title: some keys stopped working: left & right arrows, backspace To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnucash/+bug/1306500/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
