https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D296261 --- Comment #4 from Aeryn <[email protected]> --- I tried both devd configuration options on the ThinkPad T480 and it doesn't work. As I mentioned before, brightness switching before loading i915kms wi= th only efifb works without any configuration, but after loading i915kms it breaks. IIRC, on this same ThinkPad without libreboot on FreeBSD 14.X, brightness switching worked without any configuration with i915kms loaded, = so it's most likely a bug in FreeBSD related to coreboot/libreboot, because ot= her BSDs and Linux don't have this issue. --=20 You are receiving this mail because: You are the assignee for the bug.=
