Just giggled as my last meme mentioned trouble with displays and appropriately, a large chunk of the replies were “well MY displays work just fine!” (And charmingly, many were thoughts of things to check, other distros etc. It’s a very kind community, though that may also be the fediverse.)

    I can’t get the monitor to stay off. Something keeps getting it to turn back on, which is annoying because I have 3 devices plugged into it. So instead of me coming back to another device and both monitors turn on and to that device, this monitor is just always showing the one device and i have to switch the input.

      I can’t get the monitor to stay off…

      This is just a shot in the dark, but:

      I recently learned enough about the differences between HDMI and DisplayPort to boil them down in my mind to “HDMI Bad. DisplayPort Good.”

      Wild oversimplification, I know.

      So now, whenever I have display issues of any kind, the first thing I do is upgrade the cable to a DisplayPort cable.

      I mention this specifically because I have felt like my monitor wake and sleep behavior became more predictable.

      Sorry, this idea really is mostly vibes. (Informed by my perception that HDMI has a crazy amount of control signaling which itself is proprietary and inconsistently implemented.)

      But for the cost of an $8 cable, I feel like swapping in a DisplayPort has led to better display outcomes for me.

        You know what, it is hdmi. That’s not a crazy idea. The ports are hdmi on both ends though, the monitor has a displayport but my desktop is using it and the mini pc has 2 hdmi outputs. I wonder if adapter-cable-adapter would do anything for me in that case.

          Yes.

          I’m always nervous about those little black-box mysterybadapters, but I have used them and had them be fine.

          I don’t really know enough about how HDMI works to say if it helps as much as native DisplayPort at both ends.

          I suspect it might help, since some DRM will fail open when it can’t negotiate a restriction. And I imagine those dongles require keeping things simple.

          My use of the adapted setup has been rare - mostly due to not having many such adapters on hand when I’m setting things up.

          Anyway, I feel a little bad passing on my superstition; but it seems to have helped me.

          Worth a shot, I guess.
