I've been experiencing a weird behavior with some applications (e. g. Skype), since I updated my Ubuntu to 13.10 and now to Ubuntu 14.04.

When my computer "freezes" due to high CPU usage and I happen to type something in the application at the same time, the application starts to input the characters I've typed during the freeze randomly. I can type some characters correctly, but it will eventually input the memorized characters, no matter which key I press (even backspace inputs characters!).

For example, if during the freeze I type "abc", the application will receive "abc" as input even if I press the backspace button three times! The "abc" pattern will keep occurring until I restart the application.

My problem is similar to this one: Pressing back space inputs characters

At first I thought it was a problem with Skype specifically, but it is also happening with PyCharm (Python IDE), which made me believe the problem is more generic (although not all applications behave like that, just these two - that I know of).

If someone have an idea of how to fix this problem I would be very grateful :-)

  • I have the same problem, using skype and Ubuntu 14.04. Sometimes some accented characters just stop to work, ex: áéíóú doing a'b' and etc. – Tiago Cruz Nov 5 '14 at 13:00
  • I have the same issue as well, only resolution I've found is to restart it (which usually hangs at the exit screen when I try to as well, leading to having to kill it from the command line) – Chrismit Jan 20 '15 at 15:00
  • @Chrismit yes, exactly this behavior. – renatoaf Apr 7 '15 at 20:05

Googled up a respective Launchpad bug: "shuffled keys in keyboard buffer".

People replace iBus with SCIM: sudo apt-get remove ibus && sudo apt-get install scim. I am personally cautious, as ubuntu-desktop depends on ibus.

  • Excellent! I've upgraded my PC recently and since then I've had no problems (probably because the number of "short freezes" was considerably reduced). I couldn't test it, but I'll accept the answer since people on launchpad confirmed it solves the issue. I hope there is no side effect :-) Thanks! – renatoaf Apr 7 '15 at 20:12
