I am running 12.04 Ubuntu Server and my screen blanks after some time. I am unable to unblank it without power cycling the computer.

I can however log in via ssh and type who see that the tty1 terminal is active.

I have asked this question here twice before and have accepted the solutions that worked at that time.

  • using console-tools
  • editing /etc/kbd/config

These no longer work. How do I prevent Ubuntu Server from blanking the screen? Or at least unblank it without a power cycle?

I am not using X.

  • What do you mean by "These no longer work."? What happened? – schaiba Nov 26 '13 at 21:09
  • Which settings in /etc/kbd/config did you change? – basic6 Jul 24 '15 at 14:09

run the following on system startup (e.g. on Debian based systems i put it into /etc/rc.local)

 setterm -blank 0 -powersave off -powerdown 0
  • Before I put that in rc.local, I ran that command at the terminal after a power cycle (using sudo). and now my screen is off. It did not work. – Lord Loh. Nov 26 '13 at 22:11

This should not be happening. Maybe you have defective hardware that slowly overheats and then blanks? Timing how long it takes exactly after a warm reboot to blank and a cold one could tell you. The cold one (machine off for at least 10 Minutes) should take a bit longer.

  • Does not happen with a different OS! – Lord Loh. Dec 4 '13 at 6:55
