Is not necessary to use an xorg.conf file with intel card.

Have you tried to remove the xorg.conf and reinstall intel driver ?

Please try

sudo rm /etc/X11/xorg.conf

sudo apt-get install --reinstall xserver-xorg-video-intel

sudo dpkg-reconfigure xserver-xorg

and reboot your PC.

Then give the results of

/usr/lib/nux/unity_support_test -p

Thanks

OpenGL vendor string: VMware, Inc.

The right command is

gksudo gedit /etc/X11/xorg.conf

NOT

sudo gedit /etc/X11/xorg.conf

The filename is /etc/X11/xorg.conf with capital X

NOT

 /etc/x11/xorg.conf

Right command:

sudo lshw -C display (with a space between lshw and -C and between -C and display)

NOT

sudo lshw-C display

etc....

Please copy-paste the original commands from #1, #2 and #3 instead of typing them in, and send us the output.

This will help avoid typing errors.

Please do NOT ignore the instructions I gave you in post #2, or I cannot provide any help....

The output of /usr/lib/nux/unity_support_test -p , is completely wrong. I mean is not detected your card.

And you know what I see ? I see you have added the x-edgers PPA .

This PPA is for testing proposes , and not recommended for new users or at least not advanced users. This PPA offers testing packages (not stable) .. please remove this ppa with the commands below

Copy - Paste the commands from here , one by one .

sudo apt-get install ppa-purge

sudo apt-get ppa-purge ppa:xorg-edgers/ppa

sudo apt-get update

sudo apt-get upgrade

and reboot your PC .

Then give the results of

/usr/lib/nux/unity_support_test -p

apt-cache policy xserver-xorg-video-intel

ls /etc/X11/

Thanks

Your Terminal output raises several questions:

1) do you usually log in as root user? Or do you usually log in as normal user? It is better to use sudo instead of using the root account. Please read this: https://help.ubuntu.com/community/RootSudo
2) did you install Ubuntu side-to-side with Windows in a dual-boot configuration?
3) did you install Ubuntu in VMWare or Virtualbox (virtualization software) instead of installing to a real physical partition?

The following Terminal output is also very bizarre:

root@ubuntu:/home/b2rb2r# sudo rm /etc/X11/xorg.conf
rm: cannot remove `/etc/X11/xorg.conf': No such file or directory
sudo rm /etc/X11/xorg.conf
root@ubuntu:/home/b2rb2r# sudo rm /etc/X11/xorg.conf
rm: cannot remove `/etc/X11/xorg.conf': No such file or directory

So you are unable to remove the file /etc/X11/xorg.conf , but the command

cat /etc/X11/xorg.conf

showed the contents of the file....

I do not understand that....

beats me. yet i use root terminal normally. i have now removed root terminal. i will be careful in future. do u suggest i reinstall 12.04.....

2) did you install Ubuntu side-to-side with Windows in a dual-boot configuration?
3) did you install Ubuntu in VMWare or Virtualbox (virtualization software) instead of installing to a real physical partition?

ans to both is negative. hav installed to hdd.

I suggest booting various LiveCD's from different distributions of GNU/Linux until you find a distribution where everything works out-of-the-box, including the right screen resolution. This is what I would do.... I suggest first trying Lubuntu 12.10, Kubuntu 12.10, then other distributions like Mint and Debian....

I am suggesting this, because Ubuntu is not running in virtualization software like Virtualbox (on your PC) and deleting the /etc/X11/xorg.conf file did not solve your issue, which is strange.....

I hope others can give a better suggestion....

Just to give you an example of how different your /etc/X11/xorg.conf file is, when compared to mine: here are the contents of my /etc/X11/xorg.conf file:

Section "Device"
        Identifier "intel"
        Driver "intel"
        Option "AccelMethod" "sna"

Nothing else in my /etc/X11/xorg.conf file. My screen resolution is just fine, but I am using a Dell Latitude E6500.

And I am running the razorqt desktop environment instead of Gnome, KDE or Unity (2D or 3D)....
