    you know I noticed that you guys had just added the script? I completely erased my old and put in the new one, then went to system>preferences>display and was able to change my resolution to the appropriate setting. That was pretty great. it worked just as good.

    Go to Applications on your top left of the screen, then click on Accessories. After that click on Terminal. That will open your command, then type this (EXACT!). gksudo gedit /etc/X11/xorg.conf this is case sensitive. That is how you get into the thing that will let you edit your video driver config.

    Than you copy this from here.

    Section "Monitor"
    Identifier "Configured Monitor"
    HorizSync 31-65
    VertRefresh 50-120
    EndSection

    Section "Screen"
    Identifier "Default Screen"
    Monitor "Configured Monitor"
    Device "Configured Video Device"
    DefaultDepth 24
    SubSection "Display"
    Viewport 0 0
    Depth 24
    Modes "1280x1024"
    EndSubSection
    EndSection

    Then you need to copy your original setting to notepad or something and save it so if your screen messes up good than you can go back and put in your old code. After you pasted the new code into your editor, click "save" and exit. Reboot or Re-log back in and you will notice your screen will glitch a little, so then go to System>Preferences>Display and change your screen resolution to the proper size. I had to change mine to 1152x864 and now it works perfect, no problems. It took me 3 different sizes to find the right one, but just going down does not mean your screen will get smaller, because the one above my setting now was tiny and only fit on half of my screen.

    that didn't copy right on here. That script you can get from page 1 and it should be on one of the first comments.

    I was so close to pulling my hair out trying to set up my DLP TV And I couldnt get better than 640x480 and I knew the tv supported alot higher resolution. Now I am enjoying 52 inches of DLP Ubuntu goodness.

    So happy I found this.

    Re: Change screen resolution in 9.04

    Hello,

    it succeeded with me to make the resolution 1024x768 to be an option of System->Prefrence->Display->resolution list.

    However, the screen keep annoying blinking.

    Code:
    Section "Monitor"
            Identifier      "Configured Monitor"
           ** HorizSync       31-65
            VertRefresh     50-87
    EndSection
    
    Section "Screen"
            Identifier      "Default Screen"
            Monitor         "Configured Monitor"
            Device          "Configured Video Device"
            DefaultDepth    24
                 SubSection      "Display"
                    Viewport        0 0
                    Depth           24
                    Modes           "1024x768"
                 EndSubSection
    Without using HorizSync values it blinks with annoying blinking, when I use HorizSync value the screen turns into mssy and I could not deal with it.

    How could I fix this?

    When use smaller VertRefresh range 50-75 the 1024x768 resolution does not be available.

    My Screen is TVM LR 4G 14" It was work at 1024x768 resolution on Windows
