graphics card stops rendering when monitor in power saving mode?
I have a long-running rendering OpenGL application which renders for about 10 hours, grabbing pixels using glReadPixels. During this render process, my monitor goes into power-saving mode and shuts down. (Aside from the power-saving mode, I have only a "blank" screen saver.)
It appears that when the monitor is powered off that the video card stops rendering, and glReadPixels returns data from an old frame. When I move my mouse, which wakes up the monitor, frames are once again rendered properly.
I don't know whether this occurs under windows, but it does occur on 8178 on a 6600 (Linux x86_64).
How can I fix this? Is there a better way to retrieve content from the video memory such that the video card will be sure to actually render the frame?
Thanks for any suggestions,
PS: I'm assuming that disabling the screensaver will probably fix the problem, but I haven't tried that yet.
