For about a year now I was able to use the following command to turn off the display on my laptop from the console (UI/Gnome fully disabled):
sudo vbetool dpms off
I had this in a cron job and it worked fine, but recently I noticed it had stopped working. When I run it manually, I get the following message:
Real mode call failed
I also tried xrandr
but I get the following message:
Can't open display
Any idea what is going on? I couldn’t find any useful info by searching online.
I’m also open to any other command to turn off the display. This laptop is basically a headless server so I want to keep the display turned off at all times.
