Xorg.conf nVidia ION resolution

Sorry for my English.
I have this board: ASUS AT5IONT-I, Atom D525, ION2, PCI-E 4X, 2xDDR3 SODIMM, Gbit LAN,E-sata, USB3.0, DVI, HDMI, Fanless, Heatpipe, Mini-ITX.
And, trying to make HTPC.
I install Arch with openbox, but the problem is with video resolution.
I use my 32PFL9606H Philips TV 32''.

I set proper 1920x1080 resolution is xorg.conf but "xdpyinfo | grep dimensions" reports: "dimensions:    1280x800 pixels (338x211 millimeters)"

here is my xorg.conf:

# nvidia-settings: X configuration file generated by nvidia-settings
# nvidia-settings:  version 275.09.07  (buildmeister@swio-display-x86-rhel47-03.nvidia.com)  Wed Jun  8 16:05:05 PDT 2011

PS: I deleted /var/log/Xorg.0.log file, but after reboot it is not recreated. Why? And remember that it said something like:
"[   185.106] (==) NVIDIA(0): No modes were requested; the default mode "nvidia-auto-select"
[   185.106] (==) NVIDIA(0):     will be used as the requested mode.
"
although I was set mode to 1920x1080

Re: Xorg.conf nVidia ION resolution

Hi !

Please don't use xorg.conf, edit the files inside /etc/X11/xorg.conf.d/ instead.

I also have an ION board and have working HDMI connection with audio at 1920x1080 using the below configuration. Remove your xorg.conf and then edit these files:

• /etc/X11/xorg.conf.d/10-monitor.conf

  Section "Monitor"
      Identifier    "Monitor0"
      Option "ExactModeTimingsDVI" "True"
      HorizSync 14-70
      VertRefresh 48-62
      Modeline "1920x1080-TV" 148.35 1920 2008 2152 2300 1080 1084 1089 1125
      Option         "DPMS"
  EndSection
  
  Section "Screen"
      Identifier "Default Screen"
      Monitor "Monitor0"
      Device "Default nvidia Device"
  
      SubSection "Display"
          Depth 24
          Modes "1920x1080-TV"
      EndSubSection
  EndSection

• /etc/X11/xorg.conf.d/20-nvidia.conf

  Section "Device"
          Identifier "Default nvidia Device"
          Driver "nvidia"
          Option "NoLogo" "True"
          Option "ModeValidation" "NoEdidModes"
          Option "UseEdidDpi"     "False"
          Option "DPI"            "100 x 100"
  EndSection

Please note that the above Modeline works on my TV (a 22'' low cost brand one) but I cannot guarantee it will work on yours.

Try that first, then if it doesn't work, try to generate one using the cvt command, and replace the Modeline:

cvt 1920 1080

it should output something like this:

# 1920x1080 59.96 Hz (CVT 2.07M9) hsync: 67.16 kHz; pclk: 173.00 MHz
Modeline "1920x1080_60.00"  173.00  1920 2048 2248 2576  1080 1083 1088 1120 -hsync +vsync

If this method doesn't work either, try the method explained here (which is the one I've first used to find the right Modeline). Its tricky method, and requires a bit of work and lot of patience ... just don't give up

Finally, a little bonus . To have working HDMI sound, I have to put these lines in /etc/asound.conf:

• /etc/asound.conf

  pcm.!default {
         type hw
         card 0
         device 3
  }

Again, you may need to change the device index in your case. You can list alsa devices using aplay -l command:

**** List of PLAYBACK Hardware Devices ****
card 0: NVidia [HDA NVidia], device 0: VT1708S Analog [VT1708S Analog]
  Subdevices: 2/2
  Subdevice #0: subdevice #0
  Subdevice #1: subdevice #1
card 0: NVidia [HDA NVidia], device 1: VT1708S Digital [VT1708S Digital]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: NVidia [HDA NVidia], device 3: HDMI 0 [HDMI 0]
  Subdevices: 0/1
  Subdevice #0: subdevice #0
