How do I force a resolution of 1024x768?

Enter the command below in your terminal:
```
gksu gedit /etc/X11/xorg.conf
```

Copy and paste the following options into that file:

Section "Device"
    Identifier    "Configured Video Device"
EndSection

Section "Monitor"
    Identifier    "Configured Monitor"
    HorizSync       30.0-62.0
    VertRefresh     50.0-70.0
EndSection

Section "Screen"
    Identifier    "Default Screen"
    Monitor        "Configured Monitor"
    Device        "Configured Video Device"
    DefaultDepth    24
    SubSection "Display"
        Depth    24
        Modes     "1024x768" "800x600"
    EndSubSection
EndSection

Save your edits, and restart (log out and back in or reboot).

Enjoy.

Here is my solution using xrandr to force a resoultion of 1280x1024 at 75hz... Place the following in ~/.xprofile

#!/bin/bash
xrandr --newmode "1280x1024_75.00"  138.75  1280 1368 1504 1728  1024 1027 1034 1072 -hsync +vsync
xrandr --addmode VGA1 "1280x1024_75.00"
xrandr --output VGA1 --mode "1280x1024_75.00"

Note: VGA1 is the display device you want to adjust... also you can create any new modeline you might want/need by using the cvt command. I found the reference URI: https://wiki.ubuntu.com/X/Config/Resolution

You can follow the same method you used before, but if you need to create xorg.conf do so as follows. From the command line ("Terminal"):

gksudo gedit /etc/X11/xorg.conf

Paste your configuration in there and save it. Now the file should exist and you should be able to edit it like you did before.

If you need more help after you get that far, edit your question and we can continue. :)
