technical post: installing linux
on HP laptop Elitebook 840 G3, and some comments
I was afraid that linux won't install since it is not officially supported (it was sold with "Free DOS", I did not try it). Still things are much better than they could be.
It has 1Tb HD and 256 G flash drive, 32 G memory
Works without known problems:
- USB boot (I used Ubuntu 17.04)
- WiFi during installation and later use
- hi-resolution screen: the size of fonts is very reasonable out of the box
- external VGA output on the notebook at on the dock
- external displayport output on the notebook at on the dock
- usb ports on the dock (for mouse)
- sound on the notebook (including headphone/mic with 3-wire 3.5mm connector); btw, the sound is better than I expected from such a small device
- connection with external USB sound card (Audiogram) OK, do not checked the delays yet
- touchpad, buttons
-external USB mouse
- input language change
- suspend
- shutdown
-combination of internal screen and VGA external screen (dual display; see below about inconvenience)
-combination of internal screen and Displayport screen (with the same resolution as the internal one, dual display) both with the dock connector and the internal connector
- texlive installed without problems
Does not become hot. Slightly faster that Macbook pro 2011 and several times faster than macmini.
Keyboard is OK, but I do not know whether is it robust, feels a bit delicate. The trackpoint cap easily goes off when touched.
some problems:
- skype sometimes works normally (after installation as described with 32 bit library), but sometimes misses the calls for unclear reason, do not know what happens
- sometime an error message appears about nautilus, do not know why
- some programs produce almost unreadable messages due to the high screen density. Also using the external monitor together with the internal screen creates a problem, since for (my) external monitor the density is much less, so the fonts become huge when the window is opened or moved on the external monitor. Do not see a clear way to use different fonts for different screens...
- bluetooth audio adapter (Logitech) sometime does not connect
Does not work:
- suspend when notebook is closed (one should do this explicitly)
UPDATE: solved by editing /etc/systemd/logind.conf having now two uncommented lines "HandleLidSwitch=suspend" and "HandleLidSwitchDocked=suspend"
- audio output on the dock
- sometimes (rarely, probably this is connected with dock usage) the screen hangs, only mouse works (reboot using alt+F? works)
- skype does not seem to work with standard microphone+headphone connector (3.5 mm four-contact one), and (it seems) with Bluetooth audio
Did not try yet:
4k display
multidisplay configuration (the dock has several Displayport outputs)
Willing to test something if requested...

Re: tested
HP известна проблемами с оригинальным хардвером, скорее всего нужен драйвер для реакции на закрытие крышки.

Re: tested
зайдите в консоль по Ctrl-Alt-F1 и выполните
sudo apt install gnome gnome-shell
sudo dpkg-reconfigure gdm
последний должен показать текстовое меню со списком из уже установленных менеджеров
Re: tested
Alt+F2: "a start job is running for Hold until book process finishes up"...
Re: tested
если GRUB при загрузке показывает меню, то можно выбрать отказоустойчивый режим загрузки, и зайти в консоль в нем.
если не получится, то можно загрузиться с установочного образа, смонтировать файловую систему ноута в chroot и ковырять пакеты, как написано выше.
самый простой способ, однако, переустановить с нуля, но это Вы и без меня понимаете :)
