Running Leia stable (18.0 Git:20190128-d81c34c) on Linux Mint 18.3 Sylvia

Whenever Kodi is idle/video paused for 10 minutes, it switches off the screen. I've checked screensaver settings in Kodi and it is disabled.
I've checked screensaver settings in Cinnamon and MATE and they are both disabled also

Is there a way of disabling this please ?

[ronie]

if you haven't done already, check the power saving options as well (both in Mint as in Kodi as well).
most linux distros will have a 'blank screen after X minutes' option under the power settings.

in Kodi, check Settings > System > Power saving > Put display to sleep when idle

[wolf30uk]

Sorry, should have mentioned that I've already checked the distro and Kodi power saving, and both are disabled.

[wolf30uk]

Incidentally, it never went to sleep in Kodi 17.6

[ronie]

could you post a Debug Log?

- enable debug logging in kodi
- restart kodi
- let it idle for 10 minutes until the screen goes blank

[wolf30uk]

OK, thanks. Did that. When the screen went blank, checked the log and there were no additional entries.

as there's nothing logged, it's not very likely the screen blanking is initiated by kodi.

can you run this command in a terminal and paste the output here?
xset -q

I'm having the exact same symptoms as the OP, on Ubuntu 16.04.5 (same Kodi version): putting the screen to sleep is disabled in both the OS and Kodi, but my monitor shuts off after ~10 minutes. 
This started immediately after upgrading Kodi.  I've changed no other settings.  For ~2 years (as long as I've had this machine), and a few Kodi major versions, Kodi would always just dim the screen, not completely blank it or shut the monitor off.Here's the output of

xset -q

Try:

1.) xset s off -dpms
2.) kodi

from the same terminal. Still 10 minutes issue?

That seems to have done it.  Thank you!  For anyone else who's reading, since I start Kodi automatically once a certain user logs in, I ended up editing the Kodi X session:

Edit /usr/share/xsessions/kodi.desktop and point it to a new executable:

bash:


[Desktop Entry]

Name=Kodi

Comment=This session will start Kodi media center

Exec=kodi-no-blank-screen

TryExec=kodi-no-blank-screen

Type=Application

(Note the `Exec` and `TryExec`.) 

`kodi-no-blank-screen` didn't exist, so I created it in /usr/bin/ and made it executable.  It's just

bash:


#!/bin/sh



xset s off -dpms



/usr/bin/kodi-standalone -fs

 Thanks for this. A nice elegant workaround.
However surely this IS a Kodi issue as previous versions never put the screen to sleep !?

[fritsch]

It's not kodi putting you to sleep, but your system configured to do DPMS ... we are an application and - unlike in v17 - we don't kill your system settings ... if you play a video / music with viz we won't switch you anywhere.

[fritsch]

In short: if you want that your system does not go into power saving mode, disable it in the system - and this is NOT Mint / whatever screensaver.

[NickElliott]

Are you running Kodi from within Mint/Ubuntu, so you first boot into the OS and then run Kodi?

I ask because on my system if I run Kodi from the desktop the screensaver kicks in. If you boot directly into Kodi this doesn't happen.

Just a thought.

To set your system to auto boot into Kodi:

1. Create /etc/lightdm/lightdm.conf
sudo nano /etc/lightdm/lightdm.conf

2. Add the following lines (kodi is the username, substitute your Linux username)
[Seat:*]
autologin-user=kodi
autologin-session=kodi

3. Quit and save then reboot

I confirm a bug. The display shuts down in 10 minutes of idle. This happened after upgrading to Kodi Leia.
Ubuntu 18.04, Kodi in headless configuration. All sleep functions of Kodi and OS are suppressed.

I'll try the workaround, thanks.
