Hello, I have trapped in weird problem. My Setup is CentOS 6.3 Desktop edition x86_64 arch. My login screen is blinking so frequently that I am unable to see and login into it. And also I am unable to reinstall the OS because it will take very long time re-setup everything as per my configuration as well as Data. The problem is as follows: I have several months ago libgcc-4.4.6.i686. Today for installing rsyslog, I updated the package libgcc-4.4.7.i686 and libgcc-4.4.7.x86_64. Then thinking about chances of conflict, I removed libgcc-4.4.7.i686 it has also removed the cups-libs gmp gnutils gtk2 libstdc++ libtiff peazip all are i686 type. Then I installed same packages for 64 bit through yum install <above packages> Message also said successfully installed. Then I try to open another terminal window but it was suddenly closing so I thought restart might solve this problem; so I restart the computer. I am getting normal CentOS login backgroud but getting faster blinking screen. How should I solve this problem (except formatting the CentOS) as CentOS is the only OS on that machine. 1. How to login into CentOS now?? 2. Which package should I need to install and how ?? Kindly do the needful, Thank you !! *-- Cheers, Mayur. *
