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've recently upgraded my computer and i decided to go for change over to the 64 bit ubuntu, the install went fine and i've worked most of the bugs out of it now except for my screen resolution. When i installed ubuntu last time it recognized my monitor as Samsung Syncmaster 710v and i set it to 1280 x 1024, unfortunately this time my monitor is set to "Generic monitor" and the maximum screen resolution it will let me set it to is 1024 x 768.
Check the HorizSync and VertRefresh against the specs of your monitor. 51kHz as a max for HorizSync is not enough for your resolution at 60 Hz.
PS1 Modeline might not be required after above modification
PS2 I've heard that X does not like modelines with a dot; call it something else like 1280x1024_60
PS3 Your default depth is 24 (see top of screen section) and you have not added 1280x1024 to the subsection for depth 24, so X will not use it.

Newbie Q with similar issues. I've never had a problem installing Ubuntu before. I just tried to install a version of Feisty, but I can't because the screen resolution isn't right and when I go to the screen resolution menu, it offers two choices: 800x600 or 640x480. This, of course is using the settings from the start menu, system, preferences, screen resolution...it isn't from the command line. How do I change the resolution? I need better than those two choices. I didn't have problems with Edgy. Maybe I should just go back to the old system and wait for Gutsy Gibbon?
I just installed 7.04. My graphics card is an nVIDIA GeForce 7300GS made by EVGA. My monitor is an old CRT, a Envision EN-710, which nvidia-settings calls "@@@".
My resolution is stuck at exactly 800x600. If I try to change resolution by System>Preferences>Screen Resolution, my screen resolution won't change from 800x600 and my refresh rate from 50Hz. If I open nvidia-settings, resolution sticks to auto. (All of this is with the nVidia Accelerated Graphics Driver enabled--otherwise everything sticks at 1024x768.
Here are the sections of my xorg.conf file you asked for:
I've tried to implement the solutions talked about in this thread, but I really don't know what I'm doing. I end up rebooting to major graphics problems and just replace my xorg.conf with my backed-up copy.

i just installed Ubuntu Feisty 7.04 onto my machine, which has an nVidia GeForce 5600 Dual Head. i have tried to edit my xorg.conf, i have run nvidia-settings (and i have confirmed that i am using the restricted driver), and i have run the Xconfig. i can get resolution working fine up to 1024x768, but not at 1248x1024 which is how i run it in XP. i have added modelines to my xorg.conf, expanded refresh numbers for my monitors, reduced to one screen and tried there, but cannot get the nvidia-settings to show 1248x1024. the only thing i havent done is install the latest nvidia driver because it wants to recompile my kernel and i havent figured out how to do that. heres my xorg.conf. any ideas appreciated.

On your screen1 you only have the option of 1024 x 768, I'm pretty sure the meta modes have to be the same for both monitors and you need to add the resoloution 1280 x 1024. Try this for editing you xorg.conf file http://wiki.arslinux.com/Twinview
thanks. i'll try these ideas. the resolution issue is the only realy thing keeping me from using linux instead of windows. i use firefox, thunderbird, and openoffice anyway, so i am mostly there. its the high-res twinview configuration that has been a pain for years.
See my xorg.conf below:
# /etc/X11/xorg.conf (xorg X Window System server configuration file)
# This file was generated by dexconf, the Debian X Configuration tool, using
# values from the debconf database.
# Edit this file with caution, and see the xorg.conf(5) manual page.
# (Type "man xorg.conf" at the shell prompt.)
# This file is automatically updated on xserver-xorg package upgrades *only*
# if it has not been modified since the last upgrade of the xserver-xorg
# If you have edited this file but would like it to be automatically updated
# again, run the following command:
# sudo dpkg-reconfigure -phigh xserver-xorg
