I have an HDHomeRun TV tuner on my network. It receives over the air TV signals from a medium-quality unamplified antenna in the attic, which it then sends over my home network. Silicon Dust (the vendor) makes available a little tuner application for Linux, which I have installed on both my laptop and my desktop. Using the tuner application I can watch any local broadcast. The tuner application is hard-coded to send the video to VLC, which pops up whenever I select a station and click on the View button in the tuner.
My laptop and my desktop are next to each other on my desk. It is my custom to watch the news on the desktop while I am doing something else on the laptop. The laptop (the subject of several recent threads here) has a 3840x2160 display using both the Intel video on the CPU and the NVIDIA T2000 chip on the motherboard. It uses the Intel video normally, as it is easier on the battery, and the NVIDIA video when it needs to. The desktop uses just the Intel video, feeding a 1920x1080 monitor. (I am working on plans to upgrade this to 4K, but that will take a while.) This has been working great ever since I built the desktop computer a couple years ago. Both computers run Xubuntu 18.04, up to date. About a week ago I suddenly started getting screen tearing while watching TV on the desktop, and even occasionally a 'Communication error' popup window. I spent time poking around, re-seating network cables, and such on the desktop, including reinstalling the tuner (from the Ubuntu repositories). I ran Speedtest.net on both computers and got about the same results. No applications on either computer seem to have any problem with the network, except the HDHomeRun tuner on the desktop. Yesterday it was so bad that I gave up on the desktop and watched the news on my laptop. Amazingly, there were absolutely no problems at all. So now I am scratching my head. The desktop used to work perfectly, and suddenly started having problems about a week ago. Both computers are getting the same signal from the tuner. The only big difference is that the video is different. But remember, the desktop used to work fine. I could use some suggestions for what to poke at next. Any ideas? _______________________________________________ PLUG mailing list [email protected] http://lists.pdxlinux.org/mailman/listinfo/plug
