Monitor & Resolution Problem

[marsdend]

Hi all, Please can you help me with a little problem?

I have Ubuntu 9.10 installed on the PC and the maximum resolution i can get is 1280 x 1024 5:4. This is leaving the display not very clear.

My Monitor
Edge 10 - TW190
16 x 9
WXGA 1440 x 900
Contrast Ratio 500:1

LSPCI Output

Any help would be appreciated,

You can manually specify the settings in xorg.conf:

Section "Screen"
    Identifier    "Default Screen"
    Device        "NVIDIA Corporation NV [GeForce]"
    Monitor        "TW190"
    DefaultDepth    16
    SubSection "Display"
        Depth        16
        Modes      "1400x900_75.00"
    EndSubSection
EndSection

Obviously details will need to be correct.


EDIT: Actually, does Ubuntu use xorg.conf any more?

Ok, Please can you explain how do do this, ive heard about it but not sure how to actually do it?

Thanks for your reply,
Dan

Just reading on the net, i think they have got rid of it in 9.10.

[marsdend]

any ideas?

I assume it will still be used IF there is a config for it, so lets work on that assumption.

/etc/X11/xorg.conf - on my 9.10 it shows:

Section "Screen"
        Identifier      "Default Screen"
        DefaultDepth    24
EndSection

Section "Module"
        Load    "glx"
EndSection

Section "Device"
        Identifier      "Default Device"
        Driver  "nvidia"
        Option  "NoLogo"        "True"
EndSection

I presume you would need to change it to (in bold):

Section "Screen"
        Identifier      "Default Screen"
        DefaultDepth    24
        SubSection "Display"
        Modes      "1400x900_75.00"

EndSection

Section "Module"
        Load    "glx"
EndSection

Section "Device"
        Identifier      "Default Device"
        Driver  "nvidia"
        Option  "NoLogo"        "True"
EndSection

Then restart X or just reboot and check your display options. In my example, res 1400x900 at 75Mhz.

There is no xorg.conf file in that folder?
