Re: Screen flashes once every 430 seconds...
I'm running Go5700 on Fedora Core 2 as well.
I also experience the problem.
At semi-regular intervals, there is a flash on the screen. I've not timed the flashes but roughly 7 minutes sounds not to unlikely.
This has been present since I've upgraded from normal unaccelerated drivers to nvidia's drivers roughly two months ago. I've keep updating the drivers at regular basis so I am running the latest driver as we speak.
If there is any assistance nessecary to track the problem, I am willing to assisst to the full of my abilities.
When I get home from work, I will supply the information suggested in the "If you have a problem, PLEASE read this first"-thread.
