https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=227869 Bug ID: 227869 Summary: Backlight brightness not working on Lenovo B570e Product: Base System Version: 11.1-RELEASE Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: mike.d.ft402@gmail.com Created attachment 192927 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=192927&action=edit Verbose boot dmesg. I'm aware that to control backlight you have to use graphics/intel-backlight (is there any chance to see this exposed to sysctl in the future without needing this kludge?) -- and it works if I bind it to some window manager keys. However, I can not use the brightness keys via window manager nor devd, because they generate no events at all. I have tried loading different acpi_* kernel modules, and none of them work. -- You are receiving this mail because: You are the assignee for the bug.
