    Driver support for monitor

    Dear all,

    would like to buy a dell monitor with the following spec
    DELL 2007FPB ULTRASHARP TFT LCD

    1600x1200 20" MONITOR 4:3 VGA DVI 4 USB

    However I cant find a dell hardware support library, I found https://opensource.dell.com/ but it seems a little confusing as to what it offers in terms of vdu support. Can anyone please advise? I have issues with my current monitor being too bright but having plugged an lg monitor in I can see it is likely the monitor going bad which is kind of unusual because the monitor worked fine before i switched graphics card.
    Thanks in advance.

    Re: Driver support for monitor

    Well I've been having a play around with some ideas.

    My monitor is too bright to be seen on my new graphics card.

    However if I plug my monitor into my windows laptop the brightness is fine suggesting it is not a monitor setting on the monitor itself.

    If I plug another lg monitor into my graphics card on my pc the monitor shows appropriate colours.

    Therefore it is not the card or the settings itself.

    It therefore seems a weird mismatch between the monitor and the card. This must be a drivers issue then? Though having said that, I didnt need to install any more drivers to switch to the test monitor I plugged into my computer. I have to buy another monitor then??

    Is it possible I can try installing drivers that aren't necessarily directly listed for the graphics / monitor card but would be usable none the less?

    Why don't you go into the settings that are in the monitor itself: there is usually a brightness option there. One of the buttons on the monitor should get you into the settings.

    I have tried both settings on the monitor and the computer for brightness and contrast etc. Like I say the monitor itself looks fine when I plug into the laptop and the new monitor I connect to the linux install looks fine so it is clearly something to do with the setup of drivers for card or monitor. However I am not used to swapping monitors around since I rarely get issues with them.

    Now why does this say i need to run as superuser when i did use sudo command???

    $ sudo modinfo -F filename `lshw -c video | awk '/configuration: driver/{print $2}' | cut -d= -f2`

    Re: Driver support for monitor

    I remember in windows a long time ago i was able to use a monitor driver that was different to the one specific for the monitor, can i try this in linux to see if this helps with the brightness issue?
