I use the laptop as a server with remote access. I tried installing xandr but it doesn't work.

Laptop model: Samsung NP305V5A-A05DX

Problem solved. This instruction helped: How to turn off monitor on Ubuntu Server

  • Welcome to the Ask Ubuntu community. To help in troubleshooting your issue, please include the make/model of your laptop, as there may be a way to disable your specific display device. Also, are you hoping to disable the display remotely, or via keypress/key combination? Thanks – richbl Jun 18 '23 at 23:15
  • @richbl Oh, okay. Laptop model is Samsung NP305V5A-A05DX – Sentyreon Jun 18 '23 at 23:18

One approach to resolving your issue (called "screenblanking") would be to use the consoleblank kernel option, which blanks the device's display after some configured period of time. There's a good prior discussion of this here on AskUbuntu.
