The display on my Laptop got corrupted after accidentally executing a script intended for my Desktop with NVidia driver.

The driver on my laptop is (lspci | grep VGA):

Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (rev 0c)

The laptop boots up fine in FailSafe Mode but when I try to reconfigure graphics using the option on screen, nothing happens and it stays on the same screen.

I tried sudo dpkg-reconfigure xserver-xorg but there was no message and it came to next line.

Is there a simple way to reconfigure my XServer Display and bring to back to the earlier stage.

Without knowing what the script did, it's pure guessing. But here's mine: Move the xorg.conf (if it exists) and restart the laptop in normal mode. sudo mv /etc/X11/xorg.conf /etc/X11/xorg.conf-broken. –  Bobby Oct 24 '10 at 15:47
    
The script was from webupd8.org/2010/10/script-to-fix-ubuntu-plymouth-for.html and I have rollbacked the changes. The xorg.conf does not exist but xorg.conf.failsafe exists. As the display is fine in failsafe mode, I tried copying it as xorg.conf but that also didn't help and on normal login I go to text based login screen. –  Chakra Oct 24 '10 at 15:50
    
Hi hhlp, unfortunately there is no backup of xorg.conf.I had tried executing the command mentioned by you but it comes down to next line without any output on terminal. –  Chakra Oct 24 '10 at 15:59

Option 1
You need to manually go through and undo the changes:

sudo apt-get remove v86d

Edit /etc/default/grub and reset to these two lines:

GRUB_CMDLINE_LINUX_DEFAULT="splash quiet"
#GRUB_GFXMODE=640x480

Edit /etc/initramfs-tools/modules and remove the line with uvesafb (mine has no entries beyond the initial comments).

Delete /etc/initramfs-tools/conf.d/splash

Run sudo update-grub2, sudo update-initramfs -u, and reboot.

Option 2

I've just found a script here that will automatically perform the above steps: plymouth-resolution-fix-revert-back.sh.zip

I had executed the script mentioned in Option 2 but it had only removed v86d. After following the instructions in Option 1, I am able to get X work in normal mode but now the plymouth boot screen is not coming and I can also not enable Compiz effects. Is there a way I can redo the graphics setup which happens on clean installation. Thanks for your answer. –  Chakra Oct 24 '10 at 16:20

Everything should be picked up automatically if you delete /etc/X11/xorg.conf –  Jonathon Oct 24 '10 at 17:23
    
I backed up xorg.conf and restarted the machine. Plymouth is still messed up with I can live with it. bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/… –  Chakra Oct 25 '10 at 4:47
