Robert, I have just noticed now that my BBB is no longer blanking the HDMI output after a period of inactivity. Prior to these changes the display would blank after some period of inactivity, and I would have to move my mouse to get it to start sending video again. It has been sitting unused for an hour or more now (there is an ssh session open), and it has not blanked the screen. I googled Debian screen blanking and discovered what I think your .xsessionrc commands are doing. xset s off # don't activate screensaver xset -dpms # disable DPMS (Energy Star) features. xset s noblank # don't blank the video device I suspect you have disabled the DPMS features that were shutting down the HDMI video output. I don't need a screen saver, but I would like the video to blank after a while. So I executed an xset +dpms command and then an xset q to check the current settings and verify that DPMS was enabled. With DPMS enabled I waited for 600 seconds (10 minutes), and my display blanked as I wanted. I see that many people are searching for a way to disable screen blanking, so I think this is one of those things that should be added to your FAQ for simple ways to accomplish basic setup changes. I think the display should blank by default out of the box both for the energy savings (135,000 BBB boards could be preventing their monitors from going to low power mode) and to provide a similar experience to what one gets using a Mac or PC. The FAQ should explain how to change it, both to blank or not blank. Is there any other reason you are disabling DPMS? -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
