OK, let's try this again- I will try to give a better description.
Yes - KDE version.
Correct - to the world icon ( rules out nvidia )
After letting screen stay where it locked up at "world" icon for 6-7 Min., I get the crash screen:
PID: 2017 ( or 3696 at another time )
Signal: segmentation fault (11)
Clicking OK returns me to login screen where I can repeat this as an endless loop...
Rereading my posts from last night reinforces my resolve to not post after drinking, really sorry for being the cyberinebriate poster child...
