Unfortunately, I knew that NVIDIA works. Different way the calls are made. I had to go back to doing acpi_call and the VBRC to set brightness between 0-16. While not a button, it still works.

Do you have USB powered after resume? 2013/3/6 Sergey Nasonov <snasonov@bcc.ru> > > ------------------------------ > > 2012/10/20 Erich Dollansky <erich at alogreentechnologies.com <http://lists.freebsd.org/mailman/listinfo/freebsd-acpi>>; > > > > Hi, > > > > > > On Sun, 21 Oct 2012 02:20:22 +0200 > > > Jan Hannibal Smith <jan.schreib at gmail.com <http://lists.freebsd.org/mailman/listinfo/freebsd-acpi>>; wrote: > > > > > > > Hey Guys, I just installed FreeBSD 9.1 RC2 on my ThinkPad x230, so far > > > > everythings works fine except the keys for the brightness adjustment. > > > > > > > > I tried the tricks I found for the x220 series but nothing helped. > > > > Does anybody got a clue how I can get these buttons to work? > > > > Maybe there is a patch for the kms driver? > > > > > > > can you check if the keys do even generate events? > > > > > > They do not generate them on my X220. > > > > > > If they do not generate events, you can use only the command line to > > > change brightness. > > > > > any info on this?
