I am running Mageia 3 with KDE.
I went into the MCC to enable 3D effects as was prompted to install the Compiz Fusion packages.
After installation, there was a message stating "Must logout and log back in for changes to take effect".
So I logged out but I can no longer log back in.
After entering username and password, a window opens with selections for either "No 3D Effects" or "Compiz Fusion".
Regardless of my choice, after clicking the "OK" button I next get the popup window stating "Must logout and log back in for changes to take effect".
At this window, regardless of whether I click "OK" or "Cancel" I am taken back to the login window.
So I am stuck in this loop that repeats over and over no matter what choices I make and cannot get beyond the login window into the desktop.

Thank You, Jose
