Hardware name: Hewlett-Packard HP EliteBook 820 G1/1991, BIOS L71 Ver. 01.20 07/28/2014 (from
dmidecode)Graphics
Graphics works with the "intel" driver of xorg and the "i915" kernel module.Default resolution is 1366x768, in Randr/Xrandr the laptop screen is eDP1.
The laptop display port is DP1, it works with xrandr.
Video projector: works with integrated VGA port, called "DP2" (and not
Docking station works well.

Touchpad
The touchpad is "SynPS/2 Synaptics TouchPad". It works with the synaptics driver (/usr/lib/xorg/modules/input/synaptics_drv.so). It supports two-fingers scrolling.Main configuration in
/etc/X11/xorg.conf:
Section "InputClass"
Identifier "touchpad catchall"
Driver "synaptics"
MatchIsTouchpad "on"
MatchDevicePath "/dev/input/event*"
# required for running "synclient -m 300"
Option "SHMConfig" "on"
Option "TapButton1" "1"
# disabling spurious right click emulation when scrolling with two fingers.
Option "TapButton2" "0"
Option "TapButton3" "0"
# enabling scrolling with two fingers à la Mac
Option "VertTwoFingerScroll" "on"
Option "HorizTwoFingerScroll" "on"
# as shown by "synclient -m 300", z>80 when two fingers are used
Option "EmulateTwoFingerMinZ" "80"
# as shown by "synclient -m 300", w is not used on this touchpad
Option "EmulateTwoFingerMinW" "0"

Wireless
Wireless works with kernel module "iwlwifi" and firmware "firmware-iwlwifi".Virtualization
The processor provides hardware support for virtualization. It is disabled by default in the BIOS.To enable it:
* press F12 at startup, choose Bios setup
* in the BIOS, select Virtualization Support >> Virtualization >> Enable Intel Virtualization Technology
* in the BIOS, select Virtualization Support >> Virtualization >> Enable VT for Direct I/O
Audio/Webcam
Sound works with the module snd-hda-intel ($ modprobe snd-hda-intel).$ lspci | grep Audio 00:03.0 Audio device: Intel Corporation Haswell-ULT HD Audio Controller (rev 0b) 00:1b.0 Audio device: Intel Corporation 8 Series HD Audio Controller (rev 04) $ head -n 1 /proc/asound/card0/codec* Codec: Intel Haswell HDMIWebcam works out-of-the-box.
Usage
Suspend (lid open/lid closed), hibernate works.

Errors
There is an error with ACPI and i915 that appears in dmesg:acpi PNP0501:00: Still not present i915 0000:00:02.0: BAR 6: [??? 0x00000000 flags 0x2] has bogus alignmentThose errors appear every second or so. They are related to PCI scanning, they can be triggered by:
echo 1 > /sys/bus/pci/rescanThe i915 error can be removed by adding "pci=noacpi" to the kernel command line (it disables PCI scanning)
