Since a few days, my Login Box does not appear after booting. Made all updates yesterday.. I tried to login blindly, means I do NOT SEE , only guess that i am entering in the right input field.

The Background image (blue with some bubbles) is shown. After some trial and error experiments, i found my way into my desktop ..

Have not changed anything, at least intended.

Compiz is enabled, with desktops rotating on a cube.

Hi all,
I am new to Centos and was hoping someone could help me.

No idea what might have gone wrong. Perhaps the resolution has changed and the virtual screen is larger than the physical one so you are only seeing a part of it. Please provide more information about your system by running "./getinfo.sh" and showing us the output file.

If necessary boot to runlevel 1, AKA single user mode to debug. Interrupt GRUB by typing a character such as "space" then append to the kernel line by typing "a", backspacing through "rhgb quiet" and append " 1<enter>". This should give you a root shell and not a login prompt. You should then be able to look at log files such as /var/log/messages and /var/log/Xorg.* . You can also boot to full multiuser text mode with networking by using "3" rather that "1".
