Use a browser wake lock for a visible task, or change Linux power settings when the whole machine must stay awake.
Ready. Choose a duration and press Start.
Linux screen blanking is controlled by your desktop environment and power manager. A supported browser can temporarily keep the display awake without changing those settings.
For compiles, local AI, servers, or scripts, a screen wake lock alone is not enough: disable automatic suspend for the session or use your distribution's inhibitor tools.
Start the wake lock above and leave the page visible for reading, monitoring, or presenting.
In GNOME or KDE Power settings, extend screen blanking and automatic suspend timers if needed.
Use a desktop or command-line sleep inhibitor when a local process must continue even with the screen off.
It works in current browsers that expose the Screen Wake Lock API. Browser, desktop, and power-saving policies can still affect it.
A screen wake lock targets the display. Prevent automatic system suspend separately for long terminal jobs.
Check the browser console for support, turn off battery saver, and review the desktop environment's screen blanking settings.
