Does this mean you have to use apt-get to get the deb version again? Or is there an even more complicated command? I’m wondering what happens for the other Ubuntu flavors. I’m usually running Kubuntu.

I’ve been working on that exact problem for the last couple weeks. My solution for now is rt patch and a dedicated cpu core for rt tasks. This already works pretty reliable, but I notice small delays from time to time. I gather from the article that my problem might be page swapping. I don’t know how to improve that, yet.

Also for anybody working on rt problems: I highly recommend the stress-ng tool for stress testing and finding bottlenecks of your system.

Why did HDMI succeed over display port? Always the same problems with closed source.
