View Full Version : [ubuntu] Ubuntu Dead - Resetting to defaults?

February 22nd, 2009, 11:32 AM
Hi, I was wondering. Is there a way of resetting Ubuntu to it's defaults? Because I changed my screen resolution, and that made my screen go haywire. I rebooted, but now I can't even load Ubuntu it just goes to a multi-coloured screen of death.

So is there a way to reset Ubuntu to it's defaults without entering Ubuntu graphically? As it doesn't work. I have XP Dual boot and thats what i'm on right now

if your having trouble with your display, you could log in with a live cd.
and then copy the xorg.conf file from the live cd to your harddrive.
That should reset it to the standard.
But don't quote me on that.

Please do not cross post, or post the same thing in multiple locations.

I posted a suggestion in the other thread you started.

Still can't fix this... Anyone have any ideas?

Start in recovery mode nad at the menu choose xfix, once xfix is finished select resume and continue to the desktop. THis assumes you are rinning Intrepid (v. 8.10) if you are running an older version, in recovery mode type at the prompt:

dpkg-reconfigure -phigh xserver-xorg

both actions will reset your /etc/X11/xorg.conf file to the default, and you should be able to get to your desktop.

Hi, I tried it, however it didn't fix my problem. Now for some reasn when I click resume it loads a blurred and un-responsive windows XP background.

February 24th, 2009, 10:23 AM
If I went to the 'Drop to root shell prompt' option and then did:

dpkg-reconfigure -phigh xserver-xorg

Reckon that would fix my problem? Or does that do exactly the same thing as what was stated?

Or could I do something with the Live CD?

I just reinstalled when this happened 2 me. BUT- i lost all of my work, but i had a backup.

February 24th, 2009, 10:49 AM
I'd like to see if there are any other options before I do that :(

... still having this problem almost 2 weeks after I logged my first launchpad support / 5 days since I logged here. Had two replies... where is this good support?

Have you tried going through recovery mode to the comand shell and then type startx. It may give you a GUI. If this does not work try the following command

sudo mv /etc/X11/xorg.conf /etc/X11/xorg.conf.save
then reboot.

this removes your xorg.conf file and may initiate a reset of the video setup.

To reinstate the file do

sudo mv /etc/X11/xorg.conf.save /etc/X11/xorg.conf

How about this thread:

February 26th, 2009, 08:59 AM
Thanks for replies. Peter, sadly that didn't work, thanks heaps for the response though :( Just before I try the second method, would doing this work maybe? Well, would it not stuff me up even further?

sudo aptitude reinstall ubuntu-desktop

February 26th, 2009, 09:10 AM
You need to get the package manager working with no errors, once you have done that then yes reinstall.

By all means try it, the commands I gave you will not fix the problem of missing packages, rather they should set the package manager back to match your current configuration. If it has done that then try the re-install.

February 26th, 2009, 11:49 AM
Hi, I tried it. THe package manager worked, but it didn't fix my problem. Any other ideas? I installed a new ATI driver as well, can I go back to the default Ubuntu driver somehow?

February 26th, 2009, 12:02 PM
To get back to your original driver:

Can you post the output of

more /etc/X11/xorg.conf

February 27th, 2009, 10:41 AM
It's this (had to write out on paper then type it up. But hopefully it's accurate)

Section "Device"
Identifier "Configured Video Device"
End Section

Section "Monitor"
Identifier "Configured Monitor"
End Section

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

Sorry about my late reply ;(

Try envy

Get to the recovery mode command shell and

apt-get install envyng-core

when complete


Note if it cannot find envyng when you come to run it try envy<TAB KEY> this will auto complete (I'm not sure of the exact executable name.

February 27th, 2009, 11:03 AM
Forgot to mention that you will need the -t switch

envyng -t

February 27th, 2009, 11:48 AM
Thanks for reply. It didn't work, it says that it couldn't locate some packages using apt-get. Then i tried running it (envyng -t) and it told me to do the apt-get thing. Tried again, twice but it fails all the time :(

Could I somehow install it otherwise? Is it possible to edit my installation via the LiveCD?

February 27th, 2009, 11:54 AM
How are you connected to the internet, wireless or wired?

February 27th, 2009, 12:03 PM
wireless. I had problems with that as well, but I managed to fix it eventually (http://ubuntuforums.org/showthread.php?t=1034071). I can't connect to a wired network though. I have full access to internet on my WinXP boot.

February 27th, 2009, 12:06 PM
Are you sure that you have Internet connectivity in command mode?

Can you post the apt-get errors

February 27th, 2009, 12:24 PM
It completes both the strings (both are Done for apt-get errors)

I tried envyng-core thing again. My error was more specifically:

Could not resolve au.archive.ubuntu.com

It says for me to maybe run apt-get update or try --fix (the rest of the text I can't read as it's off the screen).

February 27th, 2009, 12:31 PM
That suggests that you are not connected to the internet properly. Can you post the output of

I did some more tests, turns out I don't have internet connnectivity on the root shell..

Is there a way to re-install the graphic settings (default ones) from the LiveCD?

February 28th, 2009, 09:07 AM
Apart from xfix and xranr --auto I really do not know. I would work on getting a wired connection to the internet.

February 28th, 2009, 11:16 AM
What about reinstalling Ubuntu. If I installed it again, would it overwrite the existing installation? Becuase I don't really have anything important on it
