yasirrfc, no offence intended but why do you do this? You have proven time and time again to do stuff you don't understand and then complain when you don't like it. If you are not comfortable in getting into the innards of the OS, then you should leave well alone.

Did you even read any of the warnings about messing with the -devel repository?

I and several others have tried to help you in the past and yet you leave very little feedback or thanks.

For those that wish to help you, what are the exact steps you have taken to fix your problem? Which threads have you read to try to help yourself? What was the outcome of the steps you took?
