I upgraded 14.04 to 14.10. I installed my apps(lamp, nodejs, filezilla, phpstorm, git etc.). I have some input problems in some apps.

In Filezilla,

  • I can't use tab and delete keys
  • Some UI problems, in filezilla tabs

In Gedit,

  • After 2-3 minute I can't write anymore. (Old keys writing sometimes) (No keyboard problem) (I think GTK or RAM problem)

Try to install the ibus-gtk Install ibus-gtk package, by clicking that link or running with sudo apt-get install ibus-gtk and restart you computer. That fixed this issue for me.

It seems a lot of issues have been raised regarding input problems lately: ibus issue

Try going to

  1. Input Method > OK > YES: Change from ibus to none or xim.
  2. Language Support > Keyboard input method system: none

This is a workaround until a definitive fix is released.


  • I changed ibus to none from Input Method, Also I set Keyboard input method system to none. But problem still not fixed. But, Thank you for answer Christian :)

  • It appears that the answer was accepted prior to testing. Comment came in 1/2 hour later than acceptance.

  • It seems this has not solved the problem. As a workaround everytime that happens I restart Ibus: ibus restart
