nV News Forums - No higher resolution than 640x480 with 9400 GT, driver 185.18.36, ubuntu/xubuntu 9.10

Hi all

After installing Mythbuntu 9.10 AMD64 I can't choose any higher resolution than 640x480.
When i was running Mythbuntu 8.04 AMD64 I was able to choose 1280x768.

I tried Ubuntu 9.10 too and had the same problem.

I use the following hardware:

Monitor: Philips LCD TV 32PF7320/10
Mainboard: Asus M4N72-E
Graphics card: GeForce 9400 GT
Nvidia driver: 185.18.36

I found this thread: http://ubuntuforums.org/showthread.php?t=1087922

With nvidia-settings I found that my monitor runs with 59.94 Hz.

To test it I run gtf 800 600 59.94

Then I wanted to write the generated modeline to my xorg.conf "Monitor" section. Because there was none I just copied the monitor section from the post to my xorg.conf:

Code:

Section "Screen"

    Identifier    "Default Screen"

    DefaultDepth    24

        SubSection "Display"

            Depth           24

            Modes   "800x600"

        EndSubSection

EndSection



Section "Device"

    Identifier    "Default Device"

    Driver    "nvidia"

    Option    "UseEvents"    "1"

    Option    "DPI"    "100x100"

    Option    "NoLogo"    "1"

EndSection



Section "Monitor"

    Identifier    "Configured Monitor"

    # 800x600 @ 59.94 Hz (GTF) hsync: 37.22 kHz; pclk: 38.12 MHz

    Modeline "800x600_59.94"  38.12  800 832 912 1024  600 601 604 621  -HSync +Vsync

EndSection

But unfortunately it couldn't start X

Does anybody know what I'm doing wrong?
