I want to stop the monitor from turning off in the login and lock screen.

On the lightdm config file there is this line:


I tried to put a value of 0 and -1, but both make the screen turn off after 10 minutes.

What is the value to stop the monitor turn off?

1 Answer 1


the Elementary OS answer to this (instead of the terminal answer) is

settings -> power -> set to never turn off monitor!

  • It does not help, still monitor turns off after 10 mins. Tested both on LOKI and JUNO Beta2.

  • Well if it's a software bug then you'll need to report it as one. If this setting is available but doesn't work then it's a bug. Commented Oct 1, 2018 at 9:59
