How to set the resolution for Sony HS 20 on Ubuntu?

How to set the resolution for Sony HS 20 on Ubuntu?
I am trying to get it to 1280x768 res but have only been able to get to 800x600.
My video card is NVidia 6600 GTS

I tried this but no effect

The Process:

Open a terminal and type sudo apt-get update
Type sudo apt-get install nvidia-glx
Type sudo apt-get upgrade
Type sudo dpkg-reconfigure xserver-xorg
Select the nvidia driver from the X server driver list and follow the on-screen steps to complete the configuration
Once finished with the configuration, hold down Ctrl+Alt+Backspace to restart X server. You should be presented with a nice NVIDIA splash screen signaling that the driver is installed and working
You can test this in the terminal by typing glxinfo | grep direct (the output should be direct rendering: yes)
You can also type glxgears to watch your card at work

Try this method: http://www.mediafire.com/?3gk1nno2zto
It is a Howto video I made.

I will read that link in the mean time i wanted to share the log.

(WW) NVIDIA(0): No valid modes for "1024x768"; removing.

1280x768 is valid and how can I force that mode?

If you don't want to use the video guide, here are some instructions to follow:

Open up a terminal
Type: sudo nano /etc/X11/xorg.conf
Go down until you see a section called "Screen"
Find the subsection "Display" with 24-bit depth
Navigate to right before the first listed resolution
Type(with the quotes): "1280x768"
Hit control-x to save and quit
Restart the x-server with control-alt-backspace

I already tried that and it did not work

Then it is probably the monitor settings in xorg.conf. This is what I have:

Code:
Section "Monitor"
        Identifier      "Generic Monitor"
        Horizsync       28-70
        Vertrefresh     43-60
        Option          "DPMS"
EndSection
The Horizsync and Vertrefresh ranges need to include what they would be for your resolution. Have the Horizsync have an upper limit of 50 and the Verterefrsh have an upper limit of 60.

If X fails to start after you change these, change them back.

I watched the video and that is what I tried before.

On Windows, NVidia drivers could do the whole thing. I wonder if I should try that on ubuntu.

I tried NVidia on Ubuntu 7.04 and messed up that installation. Their driver does not support the X version on Ubunto 7.04. I reinstalled the OS to Ubuntu 6. I could try Nvidia drivers on Ubuntu 6 and see if it will help. Will it be better than what is installed by the command or are they the same thing
sudo apt-get install nvidia-glx nvidia-kernel-common
sudo nvidia-xconfig

Installing from Nvidia was more complex. Is that version better? I guess I will try it anyway. Without the ability to increase my resolution this is a dead end. Either I need to get a new projector or try out Vista.

MythTV is cool...

These are what make me think it is an issue with the monitor section of xorg.conf. The higher the resolution, the faster the monitor monitor must draw dots on the screen, and the higher the horizontal sync rate must be.

In linux, Nvidia drivers are just the drivers, without the control panel. The drivers are functioning correctly because 3d acceleration is being enabled. The only problem is in xorg.conf. I have a feeling the settings in the monitor section make it so that you can't go to the full resolution.

Edit: Actually, just post your entire xorg.conf, and I will change it for you (if you haven't already done it yourself).

i fixed it. I saw a post that said to remove all other resolutions from the xorg.conf file.
Now i just have 1280x768 which kind of works. The actual resolution is now 1280x720. I can live with that till I get my new projector. Now to go and install MythTV ... whooh...

FYI, MythTV will take some time to get set up.
