From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Monitors won’t sleep on idle pc (lemmy.ml)

So I’ve set up pop os, everything went smoothly. But I have a problem - My pc is set to turn screens off after 15 mins, also to lock itself. But when it does that, my monitors shut down for a second, then start again so I can see it’s locked, then after few seconds monitors are blank but not turned off, led indicator is active and so is backlight panel.

It bothers me because I don’t want to physically turn off my monitors every time I go afk.

Can anyone tell me where to set this up? Thx

Check the HiDPI Daemon in the Display setting...

This HiDPI Daemon is for switching between Intel video card and NVidia. On systems with different cards the program does nothing but interfere with the power management of the monitor.

What video card do you have? You might be able to remove the package.
