I have just submitted a PR to MFC the code that will fix brightness adjustmant on may laptops with modern Intel GPUs. It has been tested by at least two people and I have been using it for at least three months with no negative issues. Th author has posted that he lacks the time to MFC but that "someone else" will have to do it. Could some committer please take a look at this one? The patch touches three files, two just to add entry points for the code. The functional code is all to /sys/dev/drm2/i915/intel_opregion.c. Other than some offsets, it applies cleanly to stable. At very least, it will fix an annoyance for some people and eliminate some messages to several mail lists (stable, questions, x1l, mobile and acpi). The patch can be found it 198551, just submitted. -- Kevin Oberman, Network Engineer, Retired E-mail: rkoberman at gmail.com

I just saw that this feature got MFC'd in revision r280369 this afternoon. I've been keeping an eye on it, as it's pretty much the only feature that hasn't worked properly on my laptop and so the last remaining bit I needed for the "Golden FreeBSD Experience." I want to give my thanks to the developers involved, as well as to Kevin, who's been following this longer---and done more about it---than I have. Just another reason to love this OS, its community and its hard-working contributors. I've yet to update my systems in response to the OpenSSL security advisory, so I'll back up my local source tree and start with a clean pull this evening, and check back in a few days to report how things are working. Thanks again, all. Take care. -- "A common mistake that people make when trying to design something completely foolproof is to underestimate the ingenuity of complete fools." - Douglas Adams
