    Nvidia Driver vs. Monitor Challenge

    Hello;

    I've been reading the posts on this forum about my subject issue and I'm more confused now than before. I don't know what my problem is nor do I know how to fix it.

    PROBLEM:
    1. Kubuntu System Settings reports screen resolution at 1600x1200. Although the screen doesn't appear "squashed," it may be. Another possibility is that the resolution really is 1920x1200, but KDE is not reporting it correctly.

    2. KDE System Settings only "sees" my old monitor (Dell p1110) which was not a wide screen monitor. I can fix this of course using the KDE System Settings administrator mode, but I hesitate to do that until I know there are no driver problems.

    Using a terminal:

    - How do find out what nvidia driver is active or being used?

    - What driver should I be using?

    SYSTEM INFO:

    Athalon 2200XP CPU
    nvidia geForce 4200ti AGP X8 graphics card
    Dell 2407wfp monitor

    I've already commented out the wacom, eraser, and pc tablet lines from my X.conf file. This didn't change anything, but it wasn't supposed to either. I just thought you should know.

    I can certainly provide the code for my x.conf file and DMESG if you need me to. Please advise.

    Mark

    Re: Nvidia Driver vs. Monitor Challenge

    In the "Device" section of your xorg.conf file there is a line that looks like
    Code:
    Driver    "nvidia"
    This is the driver you should be using If it reads "nv", then search the forums for how to install the nVidia driver (there are plenty of threads to tell you how).

    As for resolution: stay away from the Monitor & Display module of System Settings, I've never known it to work properly and it's broken many good setups for me. To make sure your system is using the right resolution, you may need to edit one of the "Mode" lines found in the Screen -> Display sections of /etc/X11/xorg.conf, adding the right resolution as the first entry... hope that makes sense, if you need more help post back

      1. "glxinfo | grep OpenGL". Any mention of "mesa" means you're using software rendering (i.e. through your CPU and not GPU).
      2. Like JamesM says, "nvidia". If you need it installed, I (and many others) recommend Envy.

        Good information, thank you very much. Here's my results:

        Code:
        glxinfo | grep OpenGL
        OpenGL vendor string: NVIDIA Corporation
        OpenGL renderer string: GeForce4 Ti 4200 with AGP8X/AGP/SSE/3DNOW!
        OpenGL version string: 1.5.8 NVIDIA 96.31
        OpenGL extensions:
        And here is my Xorg.conf file (excerpt)
        Code:

        As you can see, I need to update the file for my Dell 2407wfp because it is still written for my old 21" CRT (Dell P1110). That's were I'm hesitating because I don't understand the modelines ending with + or - hsync and vsync. Since my new monitor is designed for a single resolution and scan frequency, I don't think I need the modelines at all and I'll only need one mode (1920x1200@60). Is this correct?

        Also I noticed the modes have a gray crosshatch pattern in the left margin. Any ideas why that is?

            Well, the best way would be to execute "sudo dpkg-reconfigure xserver-xorg", because that will detect your monitor's supported resolutions and refresh rates (or at least it's supposed to, some hardware manufacturers are notoriously noncompliant). Make sure you back up you xorg.conf first, though.

              Okay, I've backed up the file and I'm ready to reconfigure. According to part of the xorg.conf file that I did not include, what is the purpose of this command as opposed to the one in the quote above?

              sudo dpkg-reconfigure -phigh xserver-xorg

              I did a help on dpkg, but I still don't know what the "-phigh" options are for.

                "-phigh" only asks "high-priority" questions.
                I don't know how it defines a question as "high-priority", and I don't know how it answers the ones it doesn't ask. I've always left it out, because I don't know (and may not want to) where it gets its information from. I greatly prefer security over convenience (here, anyway).
