problem with GUI login screen in mandriva 2008
I have mandriva 2008 installed on my system. From past 2 years it was working fine. But now suddenly i weird problem has started. Whenever i boot the mandriva 2008 OS, it boots up with no problem and comes to login screen, it takes the username and password but it restarts the X-server again. But if i give wrong username or password, it shows login failed. Please help me to sort out this problem.
