I have installed 12.04LTS server edition, no GUI. At some interval, maybe 5 minutes the screen will blank and I have to hit a key to show the screen again.

I have spent hours surfing but cannot find how to change the interval. My question is where do I modify the timeout parameter (through terminal) and where should I have looked for the answer?

There is plenty of advice out there for the GUI version but none I could find for the CLI version

Hope this help you Link

The first answer will help you solve your problems.

Solution

  • 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.
