For those who want to run FreeBSD on a MacBook Pro, here're some tips to enable the iGPU, screen brightness and get suspend/resume working. Specifically, the Late 2011 model works when following this guide. However, this solution will probably work for a number of MBP models. YMMV. Both the...

Hello friends of BSD, recently, I've been struggling with backlight after X server starts on ASUS laptop. Everything is normally seen in TTY, but after executed startx or automatic slim login manager enabled boot in Xserver dims backlight to zero. For this purpose, I've installed...
