Yes, this sounds very weird but I have almost the same problem. I use US keyboard layout (I bought the U300s in Malaysia), and after a few weeks suddenly my 't' key did not work anymore. Maybe it was mapped to another key also, but I did not check at the time. I thought it was a hardware problem and after taking the laptop apart and putting it back together it worked again.
And since today, my Delete key does not work anymore. I also booted windows and I had the same issue (Delete not working) there. I checked (on Ubuntu) with 'xev' and it is mapped to keycode 74, like the F8 key. I "fixed" it with $ xmodmap -e "keycode 74 = Delete" but now my F8 also acts as a delete key. And, of course, Delete was working before and suddenly changed its behavior, which is weird. Can it be a hardware or bios problem? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/974455 Title: Lenovo u300s 't' key sends "Hiragana-Katana" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/974455/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
