Trouble logging in!

[jaspreet.lall]

Hi,

I used Ubuntu Tweak on ubuntu 10.10 and i don't remember what stupid thing i did.

Now, my ubuntu never logs on, neither in recovery mode.

I have attached the Camera Screenshot of the error screen.

And i am a beginner, and it feels bad when my ubuntu doesn't work.

Thanks in advance.

Ouch, that doesn't look good!

I would suggest that you may want to to boot using a Live Disc of 10.10 or whichever one you have, plug in a USB drive, and copy all of your Home folder to the USB drive.
Then you might have to do a reinstall of the OS.
Sadly, not knowing what you killed using Tweak, it's going to be very difficult to unkill it, even though it was probably something relatively simple.

Its not a problem for me to reinstall it, but the only thing is "Can I get everything back except that 'nonsense' of mine by copying the HOME folder?"

I'm sorry, I misunderstood your problem. I incorrectly assumed your machine booted but you could not login. Can you please post details of what does not work correctly? To do this, you'll probably need to bypass the graphic login display. To do this in RedHat or Fedora based distributions, you press the escape button as the machine attempts to boot.

Dude the basic components of your Ubuntu Desktop is not working, your second best shot is to chroot into the Ubuntu install from a live CD and make aptitude reinstall all packages -

aptitude reinstall '~i'

But I guess that'll be too difficult for you, as a result the best thing that you can do is reinstall, backup your home directory to restore settings in your newly installed Ubuntu.

You learnt a valuable lesson -- DO NOT run bogus software especially with root privileges. Unix is NOT Windows thus you can't -

1) clean up the registry
2) Defragment hard drive

Thus all 'optimization' programs are loada crap. If you wanna optimization, you gotta do it by hand.

Also you're using a 'firewall' on a Desktop computer... which's again a Windows tip. To simulate a Windows firewall, simply -

echo "ALL: ALL" > /etc/hosts.deny
