6. Running xvidtune

If you need to make adjustments to the video display, xvidtune is the tool to use.

Simply enter the command xvidtune from a shell prompt within an xterm. Read the warning and click on OK. Next click on the Auto button.

Now click on whatever combination of Up/Down/Left/Right Shorter/Taller/Wider/Narrower is need to adjust the display to your liking.

If you are using a recent S3-based card there will be some extra buttons and entries at the bottom (InvertVCLK, EarlySC, and Blank Delays). These can help solve problems of the display wrapping around a few pixels.

Once the display has been adjusted properly, press the show button to printout the correct ModeLine to put in the XF86Config to make the server always use the current display settings. To aid in copying this information to your XF86Config file, the modeline is also made the current selection allowing you to just paste it into your editor.

If you would like to adjust your other modes, you can click on the Next and Prev buttons to switch modes.

When you are through using xvidtune simply press on the Quit button.
