Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I presume you hit ctrl-alt-del and log in before entering the sudo command?
It really helps if you know your video card (and possibly chipset) and Monitor specifications. Without those we are flying blind, and can only recommend some kind of autoconfig. Two choices are: the one that comes with the system, or the one that comes with Xorg. (Often the system one DEPENDS upon the one from Xorg, but not always.)
My first try would involve booting from a live-cd that detects it properly and recording the settings and config file that results, and use that.
The longer way:
The native xorg config will run if you (as root or using sudo) run the command "Xorg -configure". This gives you a very minimal config file in your current directory to start with. See this link for testing the new config and additional steps from
or search using google.
You can use your favorite editor to make certain changes to the new config file for Xorg that specify the settings for your machines or preferred desktop. The "Screen" section is used to set the mode (resolution) and depth (bitwidth of color values).
Once you have the file created and customized, tested and verified, you can copy it to the folder /etc/X11 as xorg.conf and try startx.
The whole process can take 10 minutes if you are lucky. If you are not lucky you may have a very unusual hardware situation that is not simple to set up. In that case you might try one of the more cutting-edge distributions to see if your hardware is better supported in teh newer packages.
I would assume this message is coming from your monitor in a box superimposed on your screen. If so, it has nothing to do with X. The monitor has a built in routine to caution you when it is not working at its finest resolution.
Fixing the problem may require that you use a video card with digital output if your monitor has a digital input socket. Some monitors will not display at their best with a standard video cable and card. If configuring X still does not recognize the monitor, it may not be plug n play. If so, configure the xorg.conf file manually.
You need to tell us your distro (Ubuntu, Debian?) when you ask for help, or you may get the wrong advice. For example, it's been suggested that you alter xorg.conf, but that wouldn't be much use if your distro doesn't have xorg.conf.
Have you just installed Linux (perhaps the monitor was not correctly identified) or have you just got a new monitor (perhaps Linux didn't notice)?
I do not know monitor specs...nor how to find those... My computer was home made by my brother and frequently updated. It's always run ubuntu and I've had this monitor for some time now with no problems then this happened.
I will try some of those suggestions and let y'all know if they work. This problem has both me and my brother stumped and he works with computers for a living.
The monitor specs are on the back of the monitor. The fact that dpkg-reconfigure xserver-xorg did nothing, as you put it, means that it worked. For proof, rename xorg.conf to something like bkup.xorg.conf and run the command again. You will then have a new xorg.conf with no pop up window telling you that it was created - in Linux culture no news is good news. Then you must reboot, otherwise xserver and x will continue to use a cached version of the old xorg.conf.However, new xorg.conf will be a bare bones one.
This forum needs more info. In what way does your X not work, beyond the screen resolution message? Is the screen coming up gray? Is it blurry? Are the fonts readable? Etc.
