Sir,what will this command do(sudo apt-get install Desktop).Will it be able to solve my problem.Also if we login using usb and install any package wouldn't it be installed in os which is in usbdrive.

I think you would have to chroot into your Ubuntu-installation in order to install packages.

I'd recommend to read this thread carefully: http://www.linuxquestions.org/questi...er-oss-851447/

and then consider to chroot into your Ubuntu. If you get it, I'd recommend to reinstall gdm.

Sir when i booted with usb,I looked at the panel which contained 'places' ,clicked to open the list there i found all my partitions whether windows or ubuntu present.So I mounted the partition which I knew had the file system of ubuntu(in hardisk).Still I will check the again.

Sir,my touch pad had issues.It didn't automatically I mean i had to press fn-f8 to make it work every time i logged in.

The other day I was looking at /var/log,I saw another Xorg.1.log file which is quite different from one i sent you(xorg.0.log).Sir please have a look at this file maybe this solves my problem.

Well, the remarkable message at the end of this logfile isthis seems to be a known bug in the Xorg-server.

Markus

So,what should I do,other than formating.Sir can you tell me, of the two files which is the newest and currently working.thanks alot for your support.should I reconfigure my Xorg file? If yes, please do me a favor of posting the procedure.

Hello,

to be clear, the Xorg.0.log and Xorg.1.log are logfiles, as their names say. This files are created by the program "X-server" in order to inform the user whats going on in the system.

So you cannot configure anything in a logfile. Otherwise we don't know what's going wrong with your system. And You don't know exactly what you have done before the problem occured (if/which files or packages you uninstalled by mistake).

Well, if you want to reinstall your whole system, you can leave the home-directory as it is, but backup your data anyway.

You may otherwise post in the Ubuntuforums, maybe there is someone who knows this issue already.

And what can happen is, that after a reinstallation the problem remains, which would show us, that it is a configurationproblem anywhere in your /home directory. If you could enter your system, I'd recommend to add a new user and find out if your issue is also relevant for the new user, but since you are not able to login, I'll guess you'll have to reinstall the system.

Markus

Then I guess I'll have to do a fresh install.Sir i have windows7 installed how should I install ubuntu so that my windows don't get effected in any way.Also suggest me some books(easy to understand) through which I can understand linux.Thanks

Well, if Windows is already installed, Ubuntu will recognize it and integrate it to the bootloader automatically. It is always important that Windows is installed before Linux since Windows cannot recognize Linux-systems.
