Debian 11 Server don't suspend but turn off screen on lid close

[delyakov]

I have a local web server on Dell Latitude 5480 laptop with Debian 11.
I want to close the screen to save more power, but with the screen closed server stop working.
I turn off totally suspend mode and it works okay even on closed screen, but the screen was keeping live even when closed, which is unuseful for me.

I tried this: https://www.dell.com/community/Linux-Ge ... -p/6086201
And I tried all answers here too: https://askubuntu.com/questions/141866/ ... lid-closed

Nothing works as expected for my case - on closed screen the screen to turn off but not going to "suspend" so the server keep working.

Thanks for ideas in advance!

If you want to turn off the screen:

xrandr --listmonitors will show your screen:

Code: Select all

xrandr --listmonitors
Monitors: 1
 0: +*eDP-1 1920/309x1080/173+0+0  eDP-1

Then (in this case)

Code: Select all

xrandr --output eDP-1 --off
