LinuxQuestions.org - LCD display unexpectedly goes into low power mode with Nvidia card in FC6

Hi. I'm having an issue with my display going into low power mode.

The system is a Gateway E-4400 with 512MB RAM with a ViewSonic VG2021m display. The original AGP video card died and has been removed. Due to the age of the system and proprietary AGP card slot size, a PCI replacement card was my only viable option.

I just installed an EVGA e-GeForce FX5200 video card (128MB RAM, PCI) after getting fed up with the Radeon card I tried first. I downloaded, and installed without issue, the latest driver from Nivida. Release: Linux-x86 1.0-9631

I have the screen saver set to start after 30 minutes and all power management is disabled (AFAICT) in X and the BIOS. After a random amount of time (typically a few minutes, but sometimes several hours) the monitor drops into low power mode (screen blanks and monitor power button goes from blue to amber).

Mouse or keyboard activity wakes it back up, but here is where the heart of the problem lies: I use "synergy" (http://synergy2.sourceforge.net/) to link my laptop with this desktop system and keyboard/mouse activity generated from the laptop do not wake up the screen.

I have disabled synergy on the Gateway and still see the power down issue, so I don't believe it's related to that application.

I am running KDE 3.5.5, but have seen the same symptoms running Gnome as well.

Here is a copy of my xorg.conf, note I have already commented out the DPMS setting.

Ultimately, regardless of anything else, I really don't want the monitor to power down.

Ideas anyone?
