Hi Again I have now updated Ubuntu 11.10 to yesterdays level and tried again to follow your instructions below

sudo service LighDM stop
sudo Xorg -configure
sudo cp xorg.conf.new /etc/X11/xorg.conf
sudo service LighDM start

The LighDM service was not recognised.

aidan@aidan-Linux:~$ sudo service LighDM stop
[sudo] password for aidan:
LighDM: unrecognized service
aidan@aidan-Linux:~$

It has defaulted at the highest 1024x768 but this is distorted and the presentation is too big leading to insuffient data on a single display. My graphics card is Nvidia NV28 GeForce T1 4200 AGPx8 rev A1. I would very much like to get a higher resolution in the proper aspect ratio. Any help will be greatly appreciated.Regards Aidan_H
By any chance, is this a Dell widescreen monitor? I had similar issues with my Dell 23" widescreen lcd monitor (S2309W) on Ubuntu 10.10 - exactly same resolution. I finally got it working with some manual tweaking of xorg.conf.

Try it with lightdm instead of LightDM, Linux is case sensitive.

Display config still no solution

I have tried all the recommendations to no avail the stop DM sends me into some text mode which I don't understand and ctr/alt/del was the only way out which rebooted my system.So I am still using a distorted display, surely there is some way to tell the system of the screen resolution. I am now back on Windows 7 for the time being as at least I get a good resolution. Any further ideas would be welcome.
Regards Aidan_H

Ok lets try this, open a terminal and then type:

This is to find out which service is your display manager(DM) and the process ID so you can stop it
Code:
ps aux | grep -i dm
example here my output:
Code:
uki@ubox:~$ ps aux | grep -i dm
root       989  0.0  0.2  19480  3152 ?        Ssl  Nov22   0:00 gdm-binary
root      1060  0.0  0.3  21552  3640 ?        Sl   Nov22   0:00 /usr/lib/gdm/gdm-simple-slave --display-id /org/gnome/DisplayManager/Display1
root      1063  0.7  3.7  48792 42260 tty7     Ss+  Nov22  19:55 /usr/bin/X :0 -br -verbose -auth /var/run/gdm/auth-for-gdm-4nREc8/database -nolisten tcp vt7
root      1075  0.0  0.2  19868  3044 ?        Sl   Nov22   0:00 /usr/lib/gdm/gdm-session-worker
uki       5892  0.0  0.0   4016   768 pts/0    S+   04:22   0:00 grep --color=auto -i dm
With that output you can figure out which one is your DM and then you can kill the process,
but before it log out of your desktop, then type ctrl+atl+f1 to drop to the console and then
you will kill the process, in doubt use again the command to find it again.
The ID is the number right after the word root.

to kill the process type: kill (idnumber)
example:
Code:
sudo kill 989
Repeat the ps aux line to make sure DM and X are not running.

Now you can do the steps:
Code:
sudo X -configure
You will get output if the file is generated

Once you get this done copy(cp command) the generated file named xorg.conf.new which is the video config file to /etc/x11 directory, note it will lose the .new

Code:
sudo cp xorg.conf.new /etc/X11/xorg.conf
At this point reboot and see what happen.

This might not work yet and if not then:

This is to find out which packages for nvidia you have installed,
Code:
dkpg -l | grep nvidia
if you don't have the nvidia-settings and nvidia-96 then install those.

Code:
sudo apt-get install nvidia-settings nvidia-96
Now you will find the nvidia-settings in one of the menus(System/Adminstration or Applications), look if you have more resolutions options.

Lets see what happen.

Regards

Hi Thank you for your effort, however I got the same issue as before see below.
I did the (ps aux | grep -i dm) and the result is below.

aidan@aidan-Linux:~$ ps aux | grep -i dm
root 995 0.1 0.2 124312 4176 ? Ssl 15:55 0:00 lightdm
root 1043 1.8 0.4 123736 10100 tty7 Ss+ 15:55 0:01 /usr/bin/X :0 -auth /var/run/lightdm/root/:0 -nolisten tcp vt7 -novtswitch -background none
aidan 1721 0.0 0.0 13456 876 pts/0 S+ 15:56 0:00 grep --color=auto -i

I then typed (sudo kill 995) with the following result:-

Starting Blutooth
*PulseAudo configured for per user sessions [OK]
Saned disabled ; edit /etc/default saned [OK]

The rest of the display was black it seemed to be in some sort of text mode

After which my only wat back was ctr/alt/del to reboot the system

Did you only kill that one process , did you check if lightdm and X was running still?
note the X is the main graphical screen thing that you have to turn off.
so this process cant be running:
Code:
root 1043 1.8 0.4 123736 10100 tty7 Ss+ 15:55 0:01 /usr/bin/X :0 -auth /var/run/lightdm/root/:0 -nolisten tcp vt7 -novtswitch -background none
so then you can do 'X -configure' etc.

Hi, Yes I only killed process 995 which was the process for lightdm and after that I got the Bluetooth and the other stuff on the black screen and the only way out was ctr/alt/del to reboot as nothing else that I am aware off I could input to this black screen.

Let me guess you are doing it inside of the graphical interface? Not in the console?
If yes then you are getting a totally blank screen.

ctrl+alt+f1 to f6 you can switch between all the tty consoles(text only) Once you get there: do login, and ctrl+alt+f7 or alt+f7 take you back to the GUI if it still running.
If you are in the console(virtual or text only) and have root power
that means you can do anything, double check before do anything.
If you can stop the X then you can start it again.
For most or almost action any in Linux there is no real need to reboot the computer if you know what you are doing, but if you don't have that experience then ctrl+alt+del still available.
You can also type: reboot to reboot and to turn off computer you can use shutdown or halt.

Here you can find out more about command line interface:http://www.oreillynet.com/linux/cmd/

Thank you for your reply and yes I was using the terminal interface under the graphic system. I did then follow your instructions and got as far as Sudo X -configure after which I got a great big output but fundamentally it was an error message. It stated that the result would be in the logfile "/var/log/.0.Log" but I was unable to locate it but I think it couldn't find a file. Also It's now even more difficult to work on this system as the resolution is down to 640x480.
Any help would be appreciated.
Regards Aidan_H

Don't give up since your new to Linux things may not be so obvious or intuitive but if you keep reading about it and willing to learn you will find it very enjoyable and pleasant, because the possibilities and flexibility Linux have.

It help us to help you if you post the outputs, it is been said pretty much all the directions you need to get it going. If you manage to change it to a lower resolution then for sure you can get it to a higher one.

Post things like your xorg.conf the output you get when you do X - configure
as much info you give as much we can point the way.

Regards
