Thread: Text typing (Keyboard)

    Default Text typing (Keyboard)

    Hi guys,

    I have some problems with the text typing.
    I bought a new Toshiba C50-A laptop and I installed the Opensuse 13.1
    I noticed that when I write a text, some characters are missed.
    Initially I believed was a Toshiba keyboard hw problem, but I did some tests with Ubuntu and Windows 8 and I didn't see any problem.
    It's very frustrating write and see that the characters are not typed.
    Am I a too fast writer for OpenSuse ?
    I tried to set the keyboard speed options in the settings area, but no luck!
    Is it a keyboard hardware compatibility problem?
    Any help?

    Thank you
    Regards

    Hi Kova78,

    did you check that you are using the right keyboard layout? Maybe you have a wrong layout and that's the problem.

    And at least you could tell which characters are missing. "Some characters" is not a very detailed description. Also what keyboard. Don't let people guess these things.

    Hi :-),

    thanks for your responses :-)
    Yes, I'm using the right keyboard layout.
    The characters that most frequently are missing are: "y and o".
    I noticed that the problem is related to the typing speed (faster--> more problems).
    I did a test with 3 different OS (OpenSuse, Ubuntu and Windows) by typing a same text, the number of errors in OpenSuse are more more evident despite the other 2 OS (I deleted the 3 texts but, if you want, I can redo again the test and post the results).

    Are the characters missing in a particular program such LibreOffice writer or kwrite?
    Can you try to write your text in the terminal window for example? Maybe that is not a problem with your keyboard but a problem with an editor.

    yes, the problem is more evident in firefox, but not only...also in the terminal and gedit (I'm using gnome).
    I noticed that when I'm typing the cursor '_' remains frozen for some milliseconds and after that the characters are displayed (with the problem that some char miss).
    Honestly I don't believe that I'm so fast I saw people that are more faster than me .

    Thank you bye

    Could be graphics driver related.

    Especially GNOME3 can be very slow if you don't have working 3D hardware acceleration, as it would use Mesa's software renderer then.

    What graphics chip do you have?

    Please install the package "Mesa-demo-x" and post the output of:
    Code:
    glxinfo | grep render

    It /should/ not matter. The keyboard system should be able to capture
    entries even if the system is busy to the neck. With traditional ps2
    keyboards this was safe, with usb keyboards I'm not that confident.

    This thing could happen if something (graphics?) disabled interrupts for
    too long intervals. Assuming, of course, that the keyboard is still
    interrupt driven... which I no longer know for sure.


    Also... there are some intelligent keyboards that cache touches
    internally. Is it one of those? They are typically marked "for gamers".
    On some you can even press several simultaneous keys and they work. And
    they can record keyboard macros, too. With these things the operating
    system could make a difference.
