nvidia-xconfig unable to detect max monitor resolution

Hewson · 08-25-2009, 09:15 PM

On Kubuntu 9.04 KDE4.2.2

I installed the nvidia drivers, I ran nvidia-xconfig (as root). I have a Samsung SyncMaster 220wm, that runs at a maximum 1680x1050 (75Hz x 81kHz) and GeForce FX5200.

nvidia-xconfig is detecting a max resolution of 1280x1024. Its a bit hard on my eyes.

I tried throwing 'modes "1680x1050"' into /etc/X11/xorg.conf's screen section, this resulted with no xwindows at all.

Here is my current xorg.conf:

Code:

Section "Monitor"
        Identifier      "Configured Monitor"
EndSection

Section "Screen"
        Identifier      "Default Screen"
        Monitor         "Configured Monitor"
        Device          "Configured Video Device"
        DefaultDepth    24
EndSection

Section "Device"
        Identifier      "Configured Video Device"
        Driver  "nvidia"
EndSection

Section "ServerFlags"
        Option  "DontZap"       "False"
EndSection

any suggestions?

What is the max that the card supports?

This is a bit of a bummer to find out, but still if I could at least get 1440x900 (I have a widescreen monitor) it would be an improvement.

I've added the following line to my xorg.conf's 'Monitor' section:

Code:

ModeLine       "1440x900_60.00" 106.47 1440 1520 1672 1904 900 901 904 932 -hsync +vsync

I seem to be suffering from 2 problems at this point:
1. After setting a resolution via nvidia-settings (and saving it to my xorg.conf), I restart X, it seems like KDE on loading my personal settings is change the resolution
2. I still cant seem to get a working 1440 x 900 resolution

Try the following in your Device section

Option "ModeValidation" "NoEdidDFPMaxSizeCheck, NoMaxPClkCheck"

Here's my Device section in xorg.conf

Section "Device"
Identifier "Device0"
Driver "nvidia"
VendorName "NVIDIA Corporation"
Option "ModeValidation" "NoEdidDFPMaxSizeCheck, NoMaxPClkCheck"
EndSection

I used that to successfully get 1680x1050 with my GeForce FX 5600 and Samsung 225BW monitor.
Didn't need to create modelines...
