Monitors won’t sleep on idle pc - eviltoast

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

    Yes I had same issue on Mint on another pc (laptop with built in monitor) so it has to be fixable. I have 2 monitors - Samsung and Asus, I don’t think they are the problem. It has to be driver or some settings I can’t find. I can see mouse cursor and black screen, sometimes it will bring OS back to Lock Screen without me interacting with mouse or keyboard.

    It starts to be annoying

      I think it’s a fun (hahaha not) part of the hdmi protocol. I have the same monitor combo and the same issue with the monitors. I find that turning one off fixes it (usually Samsung since my Asus monitor completely shuts down for power saving) but I also remember at least one of my distros not having this issue. Unfortunately it’s not Ubuntu which I’m on at the moment so I can’t help but either Fedora, Debian or Manjaro didn’t have the issue.

        Happens to me with three Dell displays attached to an AMD GPU with DisplayPort. Distro is EndeavourOS. Whenever it happens there happens to be a kernel update available and, after installing it and rebooting, the problem goes away for a few days.

          I’ll have to fix it myself then. It’s weird how it works , even on the old thinkpad is the same.

        Never thought about HDMI being the issue. My new monitors are display port and have been working fine. So a HDMI bug is probably the cause
