ProxmoxVE - Turn off laptop screen Link to heading

Problem Link to heading

I have a couple of ProxmoxVE servers running on old laptops and I noticed that the screen never turns off.

The solution is to leverage the consoleblank kernel command line flag:

  • Edit /etc/kernel/cmdline
  • Append consoleblank=60 to the end of the line
  • Run proxmox-boot-tool refresh
  • Reboot
