I need help with keyboard layouts. My layout is Hungarian and on Windows I could type ć using AltGr-9 + c which is a c with an acute. However AltGr-9 + Space gives me a single quote (') and AltGr-9 + c gives me this ç a c with a cedilla despite there is an acute printed on key 9. I tried the Hungarian and Hungarian (Standard) layouts in system settings as well, but the others I cannot understand (dead keys/comma/dot... what do these mean?). I didn't notice any problems with any other characters. Thanks in advance for any advice!

  • There are many hungarian keyboards already installed in Ubuntu. Try checking the other layouts?

  • It should be bug with the dead key. I just tested English international and saw the same problem with dead acute and "c" which behaves like dead cedilla.

  • Could you please tell me where can I find info on the meaning of the kb layout names? I ofc know what's 101 or qwertz/qwerty, but what's keys/comma/dead keys? I can ofc try changing layouts randomly, but it would be nice to know.

    Comma or dot stands for the decimal point on numpad; and dead keys or eliminate dead keys is obviously referred to include dead keys in the layout.

Plain text programs

In plain text programs such as Gedit or gnome-terminal, do the following:

Right click your open document or the terminal window >> choose Input Methods from the context menu >> and then choose Simple (instead of the default System (IBus (Intelligent Input Bus))

AltGr + 9 + c will now work as intended.


In LibreOffice, the AltGr/Compose key sequences work as intended, but you need to add Shift to get to the 3rd level:

AltGr (or Compose) + Shift + 9 + c.

  • Thanks for the answer, but pressing AltGr + Shift + 9 immediately gives me the acute character, so I have no chance pressing c afterwards.

  • I tried it in LibreOffice Writer and it worked fine, which is why I specified that in the answer. I just tried it in Gedit and it's also going straight to acute. I'm not sure yet how these two editors handle it differently. Which editor are you using and will LO Writer work for you? In gedit, I can inset the correct char with ctrl-shift-u+107

  • The bug appears to be in Ibus. The plain text apps, such as gedit and gnome-terminal (these are the only ones I have tested) are running the key presses through Ibus even when Ibus appears to be off. Turning off Ibus for real solves the problem. LibreOffice is working correctly with according to AltGr/Compose key sequences. I'm not sure if it's possible to use AltGr+9+c with LO but I'm guessing not.

  • Changing the input method did the trick! Thank you!

Another alternative for inserting this character is to insert its unicode.

To insert a unicode there are two ways:


  • Press Ctrl+Shift+U, an underlined u appears;
  • insert the unicode and press space or Enter.


  • Press Ctrl+Shift+U and keep holding Ctrl+Shift, the underlined u appears;
  • insert the unicode and release the keys.

Using Character Map you can find the unicode u+107 for the small letter ć, and u+106 for the capital Ć.
