Howdy-ha, folks, Please forgive my ignorance if my question is rather mundane and/or inane. I'm pretty new to FreeBSD and its development cycle. Here's my situation: I've recently migrated my laptop (Levovo Thinkpad T520) to FreeBSD using the 10.1-STABLE snapshot, and most everything works pretty well. The only exceptions are some of the hardware keys, including the LCD brightness control keys, which is something I'd really like to have. Before going ahead with that install, though, on a lark I decided to try out the 11-CURRENT snapshot to see how it worked out. As it turns out, everything presently missing from 10-STABLE worked out of the box on -CURRENT. So I know that full support for my machine is in the source tree now and, barring any fundamental changes in the development branch, will be in the next -RELEASE. I don't really have the time, know-how or guts to maintain a -CURRENT install on this machine, so for the time being I'm sticking with 10-STABLE. So I'm wondering just how often ACPI functionality gets moved from the -CURRENT branch into the most recent release's -STABLE branch. In other words, what are the chances that the features I'm waiting for will get moved into the 10-STABLE branch in the near future? Are the ACPI devs pretty conservative with this? For the time being I can control screen brightness using xrandr, and as fond as I am with the convenience it is just a convenince all the same, so I can always remain patient. But I'm wondering if there's a way to know if and when ACPI functionality will get backported to -STABLE. I currently follow this list and the SVN mailing list for 10-STABLE, so I can also just keep an eye on them if that's the answer. Thanks in advance. - Bigby -- "A common mistake that people make when trying to design something completely foolproof is to underestimate the ingenuity of complete fools." - Douglas Adams
