When Xinerama is ON, Desktop fails .....

Hello people, 

And I'm having the following issue, and I don't have any idea what could be the problem.

I have two monitors with different graphics cards (The right monitor -> Integraded AMD card using the radeon driver  and The Left monitor -> Dedicated Nvidia card using the nouveau driver)

The problem that I'm detecting is easy: if I have the option Xinerama -> "on" in xorg.conf,   KDM fails at time to login..... why??    No idea...
simply I introduce the user and password and then  'enter' , after 4-5 seconds the system goes back to ask me again for  credentials... without error message or problem.  3 or 4 weeks before this configuration was working correctly 
(xinerama worked 10'0% fine in my system , the last time that I used  used the first week of this month)

If I use the option "off" in xinerama config (the last configuration file) , the desktop runs well, but withoput xinerama capabilities, (that makes me unhappy)

I've been looking through forums wiki etc  but I didn't find any clue... the logs file are not very usefull for me in this case...  so I need help

may be was a bug in a recent update ?? because Xinerama was working well in this system...

Thanks for your time.  Regards

my kdm LOG is the following...

he XKEYBOARD keymap compiler (xkbcomp) reports:
