Dell Latitude E5440

Tested on 12.1-RELEASE (2019-11-25).

• CPU: Intel(R) Core(TM) i7-4600U CPU @ 2.10GHz (2693.82-MHz K8-class CPU)
• Memory: 16GB
• Wireless: Intel(R) Dual Band Wireless AC 7260 (iwm(4)).
• Screen: 14“ 1600×900
• Storage: HDD 500GB

Backlight	✔	use intel_backlight from ports
Input devices	Touchpad		Model: GlidePoint. Neither two-finger nor side scrolling work. I'm yet to figure out how to configure it.

Media keys	Brightness
	Volume keys	✔
Network	Ethernet	✔
	Wi-Fi	✔	No need to load any firmware manually. It works better when using SYNCDHCP instead of DHCP in ifconfig_wlan0 in /etc/rc.conf.
Other	Battery	✔
	Bluetooth
	SD-card reader
	Smart-card reader
	Suspend & resume		Suspend doesn't yet working, it can't go down to sleep.
Ports	FireWire
	USB	✔
	VGA	✔
Sound	Headphone jack	✔
	Speakers	✔

• Legend
  • ✔ OK
  • Somewhat OK: requires additional tweaking or works worse than expected
  • Status unknown, untested
  • ✘ Does not work

• Add kld_list=“i915kms” to /etc/rc.conf in order to increase font size in the console (this kernel module is loaded automatically anyway when you start the X server).

Installation works fine from memstick in UEFI mode.

Two-finger scrolling does not work out of the box.

I've tried adding the following mouse configuration into /usr/local/etc/X11/xorg.conf.d/10-mouse.conf but without success:

Section "InputDevice"
        Identifier  "Mouse0"
        Driver      "mouse"
        Option      "CorePointer"
        Option      "Protocol" "auto"
        Option      "Device" "/dev/sysmouse"
        Option      "ZAxisMapping" "4 5 6 7"
        Option      "Emulate3Buttons" "false"
EndSection

Might not be necessary on 12.1-RELEASE.
