Is there a way to install the Speedrun timer software on Linux?

If you’re talking about LiveSplit, no. It’s a Windows program, so your only option is to run it through Wine or use the browser based version called LiveSplitOne. There might be other multi platform timers out there, but I think the big one, Llanfair, is kind of fading in relevance.

It just might be the best decision to go for LiveSplit One if you can live with it. I use Llanfair for now, but I had some issues with it before (couldnt load my settings from older version, OBS sometimes doesn't find llanfair). So I might drop it soonish. There are some others that are also not really maintained anymore: A slim one here: https://gitlab.com/theseconddennis/linux-speedrun-timer Urn: https://github.com/3snowp7im/urn
