My original mail was after a clean OpenBSD 6.0 installation. After installing a load of packages and doing what Henrik said, brightness shortcuts now work. I really don't know what did the trick because i hadn't read the replies to my email and didn't notice if the brightness control came up after suspending or package installation.
In any case, thank you all for your replies. > Sent: Sunday, September 18, 2016 at 9:38 AM > From: "Henrik Friedrichsen" <hen...@diff.cc> > To: misc@openbsd.org > Subject: Re: Thinkpad X220, can't control screen brightness via keyboard > > Try suspending to RAM and waking it up again.
