Thanks for the info Kanwar, that is interesting to know. That doesn't
work for me.

Yes, perhaps. How did you configure DPMS? What I have is this in my
xorg.conf:

In the "Monitor" section:

        Option "DPMS" "true"

and in the "Device" section:

        Option "DPMS"

(This last bit is apparently required by the NVIDIA driver.)

I am still using version 7676 of the NVIDIA driver because I am stuck on
kernel 2.6.13 (Firewire problems with 2.6.14) and Livna aren't building
driver updates for the old kernels. If you are using the latest 8178
driver maybe I should try building an rpm of it for my kernel from
Livna's src rpm and trying again. Are you using 8178?

Thanks,

Darren
