Fedora(2.6.27.5-117.fc10.x86-64)
Other
Well i can live with that.....but after i changed my compiz fusion settings and rebooted everythin goes smooth from boot to login, and desktop comes and when i click somethin that part becomes black....and when i click other parts that also becomes black and whole screen goes black... i can't do anythin...ther are two untitled folders on desktop which came automatically before i click anything and everythin goes black...i don't have any graphics card....i don't know what to do..shud i reinstall...

First, this isn't urgent for anyone but you. Don't flag your posts as urgent...we volunteer our time to help folks. Also, try to write and spell clearly.....

Second, your post makes very little sense.

You have two kernels installed, one from the initial build, the other from an update...no problems there, since the machine obviously boots fine. If you don't have a graphics card, how exactly are you getting a picture on your screen????

Chances are when you changed your compiz settings, it corrupted a file. Log in as a different user, and remove the (I'm assuming you're using KDE), the .kde4 directory in your home directory. Log back in...you'll have to set your desktop up again, but you won't lose any data.

Yaa you r correct....it is urgent 4 me and that's what i meant .......i've installed fedora abt a week ago,so i don't know more about its working...by graphics card i mean the extra grpahics card we use for playing high end games....i mentioned it because i've seen replies to this type of black screen problems in fedora relating to nvidia graphics card and all that stuff......OK i am using gnome...my problem is difficult to explain in words,you have to see it to understand clearly...everything starts upto desktop and when i start to click an icon there is a black square in that area and when i click desktop area, a small part becomes black and finally whole screen becomes black...I am stuck up with fedora one week after installation so someone has to help me....

Again, please spell and write clearly, it helps everyone to understand what you mean, and for you to get help.

As before, log in as a different user. Instead of deleting your .kde4 directory, delete your user's .gnome2 directory. You'll have to set your desktop up again, but it should work.

You don't say what settings you changed to get into this situation, nor if you're getting any errors in your system logs. Can you check your syslogs, and see if there are any errors???

Thanks for your help....I could login with another user....but which file should I delete-is it /usr/include/gnome-desktop-2.0.....There is no .gnome2 directory in /usr....There will be separate user documents and settings right...how can I access files in my user name....finding it difficult to understand those folders in main drive....How do we check system logs???

i think he means to login as root and delete the .gnome2 directory for the $HOME of the user that has the issue.

Exactly...I mentioned "your home directory" in my first post. Good catch, never hurts to me more clear...

Thanks for the reply...I will check it out....How do we check system log???
