So I’ve had my mythtv box running nicely for quite a while now but one annoying thing I couldn’t figure out was how to stop the annoying screen blanking. I’d set various dpms parameters in xorg.conf, turned off the screensaver. But it kept blanking. The most annoying part was that it hadn’t always happened.
Anyhow, I finally found the one command to stop it; xset -dpms.
ya know that screen blanking has annoyed me for so long, yet I never bothered to look into why it was occurring. Nice find Dave 😉
Screen blanking is annoying to me also. I have to try the command you found.
