I tried, it's not detecting anything. I get the pop-up about SMBus but I don't think that's relevant here? And I found a thread on r/openRGB about my specific laptop but the mods closed the thread before the poster got any help. There's a Lemmy community but based on the locked thread on Reddit I really get the impression they don't want to help.

EDIT: It's possible Acer did something scummy with this laptop, I've found some interesting projects reverse-engineering Acer's crap software to work on Linux and a lot of dead ends and at least one conversation about flashing the bios which no thank you, lol. Also a funny conversation on GitLab "By the way, the link you've provided is my Github 😄". I've looked into this before and after about a half hour I decide I don't care about RGB enough for even the half hour I'd already spent.
