increasing screen resolution, nvidia xconf.org

[Tomislav Butkovic <tomislav.butkovic@gmail.com>]

Hello,

I have been for the last few months trying to figure out how to increase the screen resolution on my Dell Inspiron 5150 running Debian Lenny with a GeForce FX Go5200 64mb.

The maximum screen resolution is currently 1024x768. 

I have entered '1280x1024' into the xorg.conf file under Screen >> Modes:

*****

Section "Screen"

    Identifier     "Screen0"

    Device         "Device0"

    Monitor        "Monitor0"

    DefaultDepth    24

    Option         "AllowGLXWithComposite" "True"

    SubSection     "Display"

        Depth       24

        Modes      "1280x1024"

    EndSubSection

EndSection

*****

This does not work, and gives me the following result in the xconf log:

*****

(--) NVIDIA(0): Connected display device(s) on GeForce FX Go5200 at

(--) NVIDIA(0):     PCI:1:0:0:

(--) NVIDIA(0):     Seiko (DFP-0)

(--) NVIDIA(0): Seiko (DFP-0): 270.0 MHz maximum pixel clock

(--) NVIDIA(0): Seiko (DFP-0): Internal Dual Link LVDS

(II) NVIDIA(0): Assigned Display Device: DFP-0

(WW) NVIDIA(0): No valid modes for "1280x1024"; removing.

(WW) NVIDIA(0):

(WW) NVIDIA(0): Unable to validate any modes; falling back to the default mode

(WW) NVIDIA(0):     "nvidia-auto-select".

(WW) NVIDIA(0):

(II) NVIDIA(0): Validated modes:

(II) NVIDIA(0):     "nvidia-auto-select"

(II) NVIDIA(0): Virtual screen size determined to be 1024 x 768

(--) NVIDIA(0): DPI set to (86, 84); computed from "UseEdidDpi" X config

I am not sure how to proceed, but it would really be nice to have a larger screen resolution to work with. Would anyone be able to assist me? I have installed the nvidia drivers the 'debian way' rather than using the nvidia installer. I believe that is the reason I don't have access to 'nvidia-settings' like some people do. I'm not too familiar with working in a terminal or with debian linux.

If anyone can assist, I would appreciate it.

Thank You,

Tomislav
