How to disable blank screensaver on Ubuntu Server?

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

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.

Thanks, it works. Not "update grub", but "update-grub" – Alex May 20 '12 at 8:37
Typo, sorry -- fixed :) Glad it worked! – izx May 20 '12 at 8:42
Is there a way to do that from Virtualbox? As in passing an option to the kernel command line? – CMCDragonkai Jun 5 '14 at 4:56
@CMCDragonkai This answer works for virtualized Ubuntu as well since it boots using grub by default too. – Melebius Jan 21 '15 at 9:42
As in, is there a way to pass it externally from Virtual Box, not from within Ubuntu? – CMCDragonkai Jan 22 '15 at 0:28

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.

A more detailled explaination can be found in this answer at superuser.

This only worked after I ran TERM=linux (since I override it in my .bashrc). – Wesley Baugh Jun 14 at 4:46
