Just17, a couple of things. The placement of "noblank.sh" is in /usr/bin not /../../kde4/autostart. I did place a copy in autostart, after making the additions suggested in the second of the two links.
The additions did not make a difference, the screen still blanked after 10 minutes. I was running kernel 3.2.18.pae.bfs. I downloaded 3.2.18.bfs and the blanking problem went away. So there is something in the kernel 3.2.18.pae.bfs that is causing the blanking.
Thanks for the help
