Hi,
I upgraded a Dell C521 from Ubuntu 6.04 to CentOS5.1. The Dell has an NVidia 6150 analog video card. The screen is an LG1952Tx.
After the screen blanking goes on, and the screen goes to sleep, the screen goes black except for a blue note saying: analog video, invalid frequency...
I have installed the NVIDIA-Linux-x86-100.14.19-pkg1. Everything works great except for the screen sleep...
Any suggestion of what I should look for?

Until you get a better advice you can disable "dpms" in /etc/X11/xorg.conf

Go into the machine BIOS and reset it to defaults. I have seen cases where aggressive BIOS settings have triggered this type of behaviour. I have about 150 machines now running CentOS 5.1 from Suse 10.0 using the same driver without issues. On a SUN Ultra 40 with an GeForce 8800 Ultra 768MB card we had an issue due to memory interleaving. Disabling this fixed it.
