USB keyboard and mouse stopped working in X ?

["linux guy" <linuxguy123 gmail com>]

I installed the latest F9 updates this morning via yum update.  

 

I'm running a Dell desktop.  I'm using a Logitech USB keyboard and mouse.  

 

They worked fine for the last several years.    I rebooted this afternoon because my computer seemed to be running really slow.   When I got to the graphical login screen, I found the keyboard and mouse no longer worked.   I could not input my password.   However, I found that ctr-F6 did work and that got me to a graphical login.   Once in a console, my keyboard worked fine.  I rebooted several times with different kernels.   My USB mouse and keyboard didn't work with any of them.

 

Any idea how this might be fixed ?

 

I seem to remember that yum installed a couple new X files this morning.   Could someone tell me which files they were and how to roll back to the previous  versions ?

 

Thanks
