Yesterday I did a fresh install of alpha4 (coming from alpha2), everything seemed fine.
I then installed Hyperion, which gave me the usual (known) non-falal errors.
But after a reboot, my leds remained dead.
Tried restarting the service, manually setting the leds’ colors through the hyperion-remote command utility, nothing worked.
Just downgraded to a fresh alpha3 now, Hyperion is working fine.
So I’m guessing something changed in alpha4 that stops Hyperion from working…
