Screen goes blank in 10 minutes: deactivate it

Problem
By default, screens under Ubuntu go blank in 10 minutes. The screen is not turned off, it just goes blank. How to deactivate this feature?

Solution
I found the solution here.

“xset q” shows you the information on the current settings for X. Sample output:

Keyboard Control:
  auto repeat:  on    key click percent:  0    LED mask:  00000002
  XKB indicators:
    00: Caps Lock:   off    01: Num Lock:    on     02: Scroll Lock: off
    03: Compose:     off    04: Kana:        off    05: Sleep:       off
    06: Suspend:     off    07: Mute:        off    08: Misc:        off
    09: Mail:        off    10: Charging:    off    11: Shift Lock:  off
    12: Group 2:     off    13: Mouse Keys:  off
  auto repeat delay:  500    repeat rate:  33
  auto repeating keys:  00ffffffdffffbbf
                        fadfffefffedffff
                        9fffffffffffffff
                        fff7ffffffffffff
  bell percent:  50    bell pitch:  400    bell duration:  100
Pointer Control:
  acceleration:  2/1    threshold:  4
Screen Saver:
  prefer blanking:  yes    allow exposures:  yes
  timeout:  600    cycle:  600
Colors:
  default colormap:  0x20    BlackPixel:  0x0    WhitePixel:  0xffffff
Font Path:
  /usr/share/fonts/X11/misc,/usr/share/fonts/X11/100dpi/:unscaled,/usr/share/fonts/X11/Type1,/usr/share/fonts/X11/100dpi,/var/lib/defoma/x-ttcidfont-conf.d/dirs/TrueType,built-ins
DPMS (Energy Star):
  Standby: 0    Suspend: 0    Off: 0
  DPMS is Enabled
  Monitor is On

The interesting part for us is here:

Screen Saver:
  prefer blanking:  yes    allow exposures:  yes
  timeout:  600    cycle:  600

It means that the screen goes blank in 600 seconds. Here is how to deactivate it:

xset s 0 0

If you want to set it permanently, you can modify your xorg.conf file as explained here. I simply added “xset s 0 0” to the end oy my .bashrc file.
