  • I would check system level logs to start like dmesg and syslog.

    Someone else might have better tips of what to grep for in the logs. One thing you could do is try to ssh into the system when it’s locked up and check the logs to see what’s being reported during or immediately before the lockup.

    Once you get a sense for what’s going on at a system level you can start to look in more specific logs.










  • I’d investigate the differences between the installs particularly around graphics and power management. It sounds like your system is getting woken up but it’s hanging at some stage in the process of resuming. You might get lucky and the issue might show up in the logs if you’re willing to investigate them.

    When I’ve run NUCs in the past I’ve had issues with external nvidia GPUs dropping off the bus when resuming from suspend. To “fix” the issue, I ended up limiting the power state to S2 or S3 so that the graphics card was kept on the bus.

    Do you know what display server, DE, power management service you were running on both? If the logs don’t turn anything up you can always compare the configs too to see how they’re suspending/waking the system.


  • I wonder if the scenario with spoken vs printed words getting treated differently is due to the differences in accuracy of google’s audio and ocr technology. Hi-res text images makes ocr very good at deciphering between grape and rape but with audio it may not be as good.

    Similarly, I wonder if the fact that google is autogenerating subtitles for videos makes a difference. When it’s spoken in a video it’s not something they’ve produced but when it’s in subtitles they have generated it is something they produced and could somehow open themselves up to legal issues? Regardless it’s still unfortunate that YouTube is forcibly censoring subtitles.



  • Those are the devices I was thinking of. If my understanding of these devices is correct, they require a direct device to device connection and would not work with packet switching devices like a switch or router. That means you would need two Ethernet lines running from your office to your living room in order to get both usb and HDMI. In addition, you run into the bandwidth issue I was describing earlier where the HDMI signal caps out at a maximum of 1080p60 and it could be lower if the signal degrades enough over the long distance.

    In my opinion your either better off going with a single fiber optic cable that can handle both usb and display (like thunderbolt or one of the newer usb standards) or using a cheap device that supports game streaming. Using a single cable is fairly expensive as the cable itself isn’t cheap and could require ancillary hardware. It could also necessitate snaking cables in your walls. As for game streaming the cost of entry can be pretty low as you primarily just need something that can decode the stream for the tv. An old laptop (I’ve even had some success with an old acer chromebook) or even a phone might be sufficient for you to give game streaming from your pc a try to see if you like it and if the latency is sufficient. My vote would be to cobble something together for free to try out game streaming to see if you like it and then go from there. RPi3’s are capable of running game streaming and don’t break the bank.


  • Would you be able to post links to the devices you’re looking at to get some context?

    If these devices are what I’m thinking of then they don’t typically run through a switch/router. Instead, they’re meant to run directly connected from device to device as if they were one long cable. The biggest downside to these types of devices is the latency and bandwidth limitations they introduce. Some of these HDMI over Ethernet devices cap out around 1080p60 (maybe even as low as 30 hz) and can add noticeable latency. With that said, I don’t think the usb over Ethernet should introduce a noticeable delay and think that one is fine — if it’s what I’m thinking of.

    Have you considered using a fiber optic HDMI cable? I have had success running a 50’ fiber optic DP1.4 at 5120x1440p120 with no noticeable latency (though I don’t play a lot of FPS) that I bought off Amazon for like $80. If you could stretch your budget a little more perhaps the usb over Ethernet (or fiber) paired with a fiber cable for HDMI might suit your needs.

    Alternatively, if you aren’t gaming at super high refresh rates and latency isn’t super critical, then streaming to a device connected to the tv in your living room might be a better choice. I’ve run both a raspberry pi 3/4 and an nvidia shield using steam link and found that to be great when gaming from different rooms in my house. Using a wired connection end-to-end the network latency is usually within the frame-time when playing at 60 fps and hasn’t been noticeable for me (again I don’t play a lot of FPS games).
