View Full Version : [ubuntu] manually changing screen dimension in pixels

July 9th, 2008, 12:35 AM
I have searched about this, but I can't understand it.

When the amd64 8.04 installation procedure doesnít set correctly the dimensions of the screen in pixels, what is a simple way to set the dimensions when the correct size does not appear in choices for
System > Preferences > Screen Resolution
after installation?

On another computer, the recommended resolution appears,
but I canít see the bottom banner unless I change the resolution to another one that appears on the choice list.

I know there are man pages for the commands used on the terminal,
but where is a list of the available commands with short explanations like what is the subject matter of the command?

OK. We need more details. For starters, what kind of monitor (HDTV, flat panel, crt...), and what graphics card are you using. What driver are you using?

This will help us help you better.


P.S. -- My crystal ball tells me it might be an overscan issue. Are you using an Nvidia 8800 card with a HDTV connected via DVI-to-HDMI by any chance? If so, please click this link (http://ubuntuforums.org/showthread.php?t=848822&highlight=dvi-to-hdmi).

The video is on the mainboard.
How do I find out what it is?
There must be a command.
The monitor is an LCD Samsung 17 inch.

Did you try

System > Preferences > Screen Resolution?

It's a standard monitor. It should work. If not, please post the result of the two following commands you need to enter in a terminal (one by one)

lspci | grep VGA
