I am new to Ubuntu and installed v8.04. My computer has a nvidia GeForce 7300GT Graphic card and a Iiama Vision Master Pro 454 Monitor. The screen resolution only gives me a choice of 800x600 and 640x480 which are far too large. Here is a copy of the original xorg.conf file:-
------------------------------------------------------------------------------------------------------
Section "InputDevice"
Identifier "Generic Keyboard"
Driver "kbd"
Option "XkbRules" "xorg"
Option "XkbModel" "pc105"
Option "XkbLayout" "gb"
EndSection

Section "InputDevice"
Identifier "Configured Mouse"
Driver "mouse"
Option "CorePointer"
EndSection

Section "Device"
Identifier "Configured Video Device"
EndSection

Section "Monitor"
Identifier "Configured Monitor"
EndSection

Section "Screen"
Identifier "Default Screen"
Monitor "Configured Monitor"
Device "Configured Video Device"
EndSection

Section "ServerLayout"
Identifier "Default Layout"
Screen "Default Screen"
EndSection
---------------------------------------------------------------------------------

I guess these are the default settings, so after a quick scan through the forum, I made the following changes to the file, but it had no effect:-

-----------------------------------------------------------------------------------
Section "Screen"
Identifier "Default Screen"
Monitor "Configured Monitor"
Device "Configured Video Device"
SubSection "Display"
Viewport 0 0
Modes "1280x800" "1024x768" "800x600"
Depth 24
EndSubSection

EndSection

---------------------------------------------------------------------------------------

Could someone give me an edited version of xorg.conf that at least initially will give me a more usable screen resolution, and ideally changes that would take full advantage of my hardware.

Many thanks in advance,

Colin

It happened to me many times, mostly when you are using nVidia or ATI graphic cards.. just delete your xorg.conf and xorg.conf.backup files
from /etc/X11/
once those files are gone restart your PC, ubuntu will run its utiliti for display configuration, select all your specs and Lowest frequency available and go on..

If you are not getting the resolution u want just change the frequency range in xorg.conf.. select 57-60 Vertical refresh rate and u will get 1024x786 resoluion

Have you installed the nvidia drivers through

System > Administration > Hardware Drivers? That is often the first step to getting correct resolution support.

Thanks for the prompt reply. I will make a note of you suggestions in case I have problems in the future. It is refreshing to find that Ubuntu is able to sort itself out even if you delete important files. I tried bigtomrodneys suggestion first and installed the nvidia driver and it worked.

Thanks again

I checked and found I did not have the drivers, so I downloaded and installed them. I now have a selection of resolutions
It is nice to know that there are a lot of helpful people here. I am enjoying my experience with Ubuntu.

Thanks,

Colin

I've had this same problem and came across that advice to delete the xorg files somewhere else. But I couldn't figure out how to delete them. I kept getting a message saying they were in use or could not be deleted. It looks like this might be a good place to start if I can actually get it done! Thanks in advance for info on how to do it....
