Thread: Contrast buttons funny

    Default Contrast buttons funny

    Hi.

    Pressing the SPECIAL key plus contrast UP or DOWN has strange effects on the contrast. It seems to go up/down on the first keystroke, and then back, then otherway, then back. So it really only has two settings.

    Should I be looking at changing my graphics card driver? Or where should I look to resolve this?

    i am confused and need more information:

    where are you pressing that "SPECIAL key" and those "contrast UP or
    DOWN" keys...(i don't think i've every found any of the three my setup..)

    what software are you running (version of SuSE and KDE4, KDE3, Gnome or
    what?)?

    what graphics card do you have and what driver are you using?

    Sorry, I meant the Fn key. So when I use the contrast up/down buttons on my keyboard.

    I am using KDE3 on OpenSuse.

    I did not install any special graphics driver. However, when I go to Configure Desktop>Display I get the message "Your X server is using the RandR extension at version 1.2 or greater which doesn't have any configuration yet".

    How do I check which driver I need or which one I am using on my graphics card?

    ok...first, not every keyboard has contrast up and down buttons...which
    means that Linux will not automatically know what to do with them...and,
    in fact you have already proven that do not work the way you expected
    them to...

    there are ways to assign different functions to each key on your
    keyboard....i don't know how, but i do know it is quite an involved and
    multi-step operation, for EACH key..

    i remember seeing a rather long article on how to do it in a Linux
    magazine 2 or 3 years ago...but, i find that mag easily...maybe try
    searching the SUSE site or google on terms kinda like

    linux key mapping assignment

    or, maybe someone who knows how will come along and help you..

    there is at least one discussion somewhere on this forum about "RandR",
    i suggest you use the web forum's search function to find all
    occurrences of that term and read what is going on there (i've not had a
    problem with it on my machine, so have not paid attention..

    if you click on the "My Computer" on your desktop, find the "Display
    info" and it will tell you your card's maker/vendor and model...and,
    also info on the driver..

    most folks with nVidia cards elect to install the nvidia drivers...there
    are several posts around here to help you out on installing those...and,
    i think also plenty of help and guidance already helping with ATI cards
    and drivers..

    but, sorry i don't have a list of pointers for you...it is just a matter
    of adding the right repository and then use YaST...

    oh, here...this will help, be sure and read all the links:

    Is there possibility of help on this? I've spent ages searching.

    I'm going to start looking at mapping keys. Before I do is there a way to test if it is the Key Allocation that is the problem (ie that the keys are not assigned to changing the contrast), so because its the graphics card driver or OS that cannot change the brightness?

    this is a laptop, right?
    why don't you post a question in the laptop forum...subject kinda like:
    "ASUS [Model] Contrast Control Buttons don't work"

    and while you are waiting, you can also search google...
    AND, you could see if there is a user forum for your laptop, maybe there
    is another person there using Linux..

    OH, and i'm pretty sure that article i read some years back on assigning
    all kinds of stuff to special keys in Linux was in one of these mags,
    maybe they have an online searchable article database:

    http://www.linux-magazine.com/
    http://www.linuxformat.co.uk/
    http://www.linuxjournal.com/
    (it had to be one of those because i know i read it in a dead tree
    format, and those are all the linux mags i've subscribed to)

    the article had a step by step how-to....of course, if the linux driver
    from your screen/card does not support contrast control, you are SOL

    and, you did follow my advice to use the search function to look up your
    "RandR" question, right?
