I have an Ubuntu server installation with XBMC. After 5 minutes of inactivity the screen turns black and can't be woken up with the remote control. However a keyboard press does wake it up. Since I don't want to use a keyboard this is very annoying.

The black screen doesn't seem to be issued by XBMC itself. It's own screensaver is set to dim after 3 minutes, which it does. XBMC is started using xinit.

I'd like to prevent the screen from turning black or find a way to wake it up using the remote.

What I've tried so far is:

  • Set GRUB_CMDLINE_LINUX_DEFAULT="consoleblank=0" in /etc/default/grub and run update-grub.
  • Add BLANK_TIME=0 and POWERDOWN_TIME=0 in /etc/kbd/config

Isn't it a duplicate of this question? – Aditya May 16 '14 at 20:13
    
@Aditya No, that's a different problem. Mine doesn't turn of while watching, only after inactivity. Also the solution is different. – André Stannek May 17 '14 at 8:14

xset -display :0 s off 
xset -display :0 -dpms 
xset -display :0 s noblank

I run this on startup (add it to /etc/rc.local) and it works fine. ;)

:0 of course has to be the display you want to keep from turning black.

Sounds promising. Did you put this in /etc/rc.local? Or does it need to be run by the same user who runs xinit? – André Stannek May 12 '14 at 19:56
    
Also if xinit is run with -- :0 I guess I have to call xset -display :0? – André Stannek May 12 '14 at 20:05
