[SOLVED] Preventing system sleep when using Advanced Launcher

deadwolfbones · 2012-05-12 19:32

Hey guys,

Kind of a weird one...

I have no problems with video playback when watching things inside of XBMCbuntu.

However, I set up Advanced Launcher (per this guide) to launch a full-screen Chromium browser window so I can watch flash-based streaming sites (ESPN3, SPEED2, etc) that don't have great plugin support in XBMC. Everything works fluidly, except that after about 10 minutes my receiver loses its HDMI connection with the HTPC. At first, I only noticed this happening while watching full-screen video, and I found that if I hit ESC to exit the full-screen video mode, the HDMI connection was immediately re-established.

Then, I left the Chromium window open on a random website, with no video playing, and walked away. About 10 minutes later, it lost its HDMI connection again. So, I'm assuming this has nothing to do with video playback and is instead some general setting somewhere in LXDE.

Anyone have any ideas as to what might be causing it?

maybe xbmcs screensaver/powersaving?

I have XBMC set to turn off the display after 60 minutes idle, but this is definitely happening much, much sooner. Could be the screensaver, I'll look into that.

You will found here a way to disable system sleep : http://forum.xbmc.org/showthread.php?tid...pid1073943

Thanks, that's potentially quite helpful.

It's actually better to just turn it off in your script that launches your application: See this post. That way the screensaver or screenblank and other DPMS functions will behave normally when your script finishes.

Thanks, I'll give it a try.

Does your solution have exactly the same effect for my purposes (preventing X from going to sleep)?

Yup. "xset s off" turns the screensaver off and "xset -dpms" prevents X from going into any of the power saving modes (standby, suspend, hibernate, etc). I use it for SNES emulation because X doesn't count gamepad input as input. Just put the rest of your launch script in place of the zsnes line in the example.

Yep, this worked great. Thanks so much!
