= Dell Latitude E7470 =

== Hardware Overview ==

 * CPU: Intel(R) Core(TM) i7-6600U CPU @ 2.60GHz (2808.14-MHz K8-class CPU)
 * Wireless: Intel Dual Band Wireless AC 8260, supported by `iwm(4)`, works
 * Wired Ethernet: Intel(R) PRO/1000 Network Connection 7.6.1-k, supported by `em(4)`, works
 * Graphics: Intel Skylake, supported by [[https://github.com/FreeBSDDesktop/freebsd-base-graphics|drm-next]] branch, works with some issues with external connectors
 * Sound: Realtek ALC293, works, also correctly detects plugging in the headphones
 * Suspend/resume: untested
 * Fn keys: only toggling keyboard backlight works; other keys (volume, display brightness, wifi toggle) do not

== Config required ==

 * Add kld_list="if_iwm" to /etc/rc.conf
 * Display brightness is too high by default. It can be tuned with https://github.com/FreeBSDDesktop/intel_backlight_fbsd, but it's reset when display goes to sleep. I've ended up by tuning it in the BIOS.
 * May also add coretemp to kld_list

== Issues ==

 * Problems with plugging/unplugging external monitors
   * You may need to restart xorg to make all external video outputs detected
   * When you disconnect all external outputs you cannot get them back until reboot 
   * See https://github.com/FreeBSDDesktop/freebsd-base-graphics/issues/155

== Notes ==

 * Don't forget to add your user to '''video''' group for xrandr to work properly
 * Removing xorg.conf is also recommended, as having it may interfere with dynamic detection of external displays and lead to system panics.
