How do I disable the blank console "screensaver" on Ubuntu Server?

Question

How to disable blank screensaver on Ubuntu Server?

There's no desktop or X, only console (command-line interface).

Answer 1

The easiest way is to add the parameter consoleblank=0 to your kernel command-line at boot-time.

• Open /etc/default/grub in your favorite editor; you will need to use sudo (for vi, nano, etc.) or gksudo (for gedit, etc.).

• Then add consoleblank=0 to the GRUB_CMDLINE_LINUX_DEFAULT=, parameter.

• e.g. yours may say:

  GRUB_CMDLINE_LINUX_DEFAULT="quiet splash consoleblank=0"

Then run sudo update-grub, and reboot.

Answer 2

Type setterm -blank 0 on any shell to disable blanking out of tty consoles.

0 disables blanking, any value greater than 0 is the time in minutes. Default is 10.

To permanently enable this you can add this line to your ~/.bashrc config.

Answer 3

Same situation, the other suggestions seemed a roundabout solution. Came across the GNU tool setvesablank on/off using apropos. It seems the best fit, trying it out to see if it fits the need.

Answer 4

This will "overwrite" whatever is in your current config for "GRUB_CMDLINE_LINUX_DEFAULT=", mine was default, so I just use the following One Liner.

sudo sed -i 's/\(^GRUB_CMDLINE_LINUX_DEFAULT=\).*/\GRUB_CMDLINE_LINUX_DEFAULT="consoleblank=0"/' /etc/default/grub && sudo update-grub2
