    Increasing Screen Resolution

    Using Jaunty. Will upgrade at a later date but for now how can I get a resolution of 1280x1024 when the highest is currently 1280x800?

    Re: Increasing Screen Resolution

    sudo gedit /etc/X11/xorg.conf

    and set the monitor display to a bigger resolution like the following:

    Section "Monitor"
    Identifier "Configured Monitor"
    DisplaySize 1920 1080
    HorizSync 30-70
    VertRefresh 60-75
    EndSection

    the sync n vert is for your own monitor specs. please adjust accordingly.

    Re: Increasing Screen Resolution

    My xorg.conf reads:

    Section "Device"
    Identifier "Configured Video Device"
    EndSection

    Section "Monitor"
    Identifier "Configured Monitor"
    EndSection

    Section "Screen"
    Identifier "Default Screen"
    Monitor "Configured Monitor"
    Device "Configured Video Device"
    EndSection



    If I enter 'DisplaySize 1280x1024' what's the worst that can happen? I can make a copy of the file for safekeeping but how could I restore it if for some reason the screen stays blank?

    Re: Increasing Screen Resolution

    you can put as you suggested. As the worst that it can happen is that it will appear smaller. The Displaysize is just to extend limit to what you can stretch in your screen resolution. I have tried this on jaunty, karmic and maverick. Somehow everytime I install the nvidia drivers, my screen will shrink to 640 by 480 and below. Using this, I can change my screen resolution upwards.

    Re: Increasing Screen Resolution

    No change, I'm afraid. My xorg.conf now reads:

    Section "Device"
    Identifier "Configured Video Device"
    Option "UseFBDev" "true"
    EndSection

    Section "Monitor"
    Identifier "Configured Monitor"
    DisplaySize 1920 1080
    HorizSync 30-70
    VertRefresh 60-75
    EndSection

    My max is still 1280x800 (16:10) with a refresh rate of 60Hz

    The particular PC I'm working on is an Advent laptop T2080

    You can try using xrandr to add undetected screen resolutions. See this tutorial on xrandr:

    Re: Increasing Screen Resolution

    Thanks for the link. It didn't solve the problem but I'll have an upgraded Ubuntu soon.

    What's strange is that under Vista, the resolution had a greater range of numbers to choose from - so the problem isn't with the hardware.

    Very strange.

    Thanks again.

    Re: Increasing Screen Resolution

    Are you running the appropriate driver for your video card? If so, is everything working properly? Have you checked that DRM is functioning (this is typically a sign of whether the video driver is working or not).

    Code:
     glxinfo | grep rendering

    Can you be more specific here? What is the output when you run xrandr in the terminal?
