OMEN HP with Linux

Recently I’ve bought a new notebook. Because I do like the design and I wanted to have something faster playing games I decided for this gaming notebook. So let’s see how to get everything working in Linux.


I decided to use Linux aside of the pre-installed Windows (not that I dare to use it, though if I’m bored I might take a look). Furthermore I decided to install Debian Stretch using a Debian Netinstall ISO on an USB-stick.


I just disabled secure boot in the notebooks BIOS (f10 is the key to enter, f9 for boot-menu). I also tried with legacy mode because I wasn’t sure how safe it is to boot into UEFI with Linux – later noticed that I really did an UEFI install – so .. disabled legacy again (need to re-disable secure boot) and everything is fine.


For that I went into Windows (what did I just write..) to shrink partitions. The notebook came pre-installed with Windows 10 Home and got something like the following partition layout:

  • NVMe
    • p1 – 260 MB – EFI System
    • p2 – 16 MB – Microsoft reserved
    • p3 – 237 GB – Microsoft basic data
    • p4 – 980 MB – Windows recovery environment
  • HDD
    • p1 – 916 GB – Microsoft basic data
    • p2 – 15 GB – Microsoft basic data

I just reduced the NVMe p3 to 136.3 GB and added an 93.1 GB Linux partition, as well as an 7.8 GB swap partition. The HDDs partition 1 has been reduced to 416.1 GB and I added a 500.6 GB Linux partition. That was good enough to get Debian installed – Later I noticed that I would like to play around with bcache – Currently my root-system has 4.7 GB used – so 15 GB should be enough space. I moved to Windows again and reduced the Windows-Partition further by ticking compress device, cleaning up, de-installing software and games which were installed, defragmenting… I was able to reduce the windows partition on the NVMe to 60,9 GB. I also removed the data-partition on the HDD which has been empty anyway. Plenty of space free now for my shiny Linux. I’ll use bcache for my /home partition since / is on my NVMe already nothing to do there.

I moved, sorted, resized partitions and finally came up with:

The new partition scheme looks like this:

  • NVMe
    • p1 – 260 MB – EFI System
    • p2 – 16 MB – Microsoft reserved
    • p3 – 61 GB – Microsoft basic data
    • p4 – 15 GB – Linux filesystem (root)
    • p5 – 8 GB – Linux swap
    • p6 – 128 GB – Linux filesystem (used as bcache cache)
    • p7 – 980 MB – Windows recovery environment
  • HDD
    • p1 – 916 GB – Linux filesystem (used as bcache backing)
    • p2 – 15 GB – Microsoft basic data

More about bcache in section Tuning on this page.


I’ve noticed that many people blacklist acer_wmi – It wasn’t loaded, though I blacklisted it as well (for no specific reason). I also blacklisted nouveau (which is required since I am going to use the nvidia card with nvidia driver).

blacklist nouveau
blacklist ibm-nouveau
options nouveau modeset=0
alias nouveau off
alias ibm-nouveau off
blacklist acer_wmi

A good place for those is in /etc/modprobe.d/, don’t forget to recreate your initramfs by issuing update-initramfs -k all -u probably followed by update-grub



While this might not be necessary, I do usually install firmware-realtek with systems which got a realtek adapter, which is the case here:

[    0.986509] r8169 Gigabit Ethernet driver 2.3LK-NAPI loaded

And due to Spectre/Meltdown I also installed intel-microcode


Connman is a really nice tool to have around for networking on desktops/workstations.

I’ve just enabled connman through systemctl enable connman and removed my manual network configuration from /etc/network/interfaces. Connman will handle network connections from now on 🙂

Graphical system / X11

Initially I was unable to setup bumblebee so I decided to set up the nvidia-card directly. Later then I found out that the acpi_osi=Linux settings caused freezes when playing around with bumblebee.

Using the nvidia card (no hybrid)

For nvidia directly I just installed nvidia-driver and had to add a xorg.conf as well as an .xinitrc:

Section "Module"
    Load "modesetting"
Section "Device"
    Identifier     "Device0"
    Driver         "nvidia"
    BusID          "1:0:0"
    Option         "AllowEmptyInitialConfiguration"
    Option         "CustomEDID" "eDP-1-1: /sys/class/drm/card1-eDP-1/edid"
    Option         "ConnectedMonitor" "eDP-1-1"
    Option         "IgnoreEDID" "false"
    Option         "UseEDID" "true"
    VendorName     "NVIDIA Corporation"

The BusID is returned by lspci (careful, issuing lspci two times after each other seems to make the system freeze) not giving that makes Xorg not find any nvidia device. AllowEmptyInitialConfiguration and the CustomEDID as well as the ConnectedMonitor, IgnoreEDID and useEDID options are necessary because Xorg reports there is no monitor connected to the nvidia card (DFP-0, -1 and -2 are available).

Apart from that, I had to remove any HorizSync/VertRefresh stuff from xorg.conf to make a resolution of 1920x1080px possible.

nvidia: .xinitrc

My .xinitrc looks like this (make sure it is executable by issuing chmod a+x on it). You’ll have to install xinit for this to work.

jean@asuna:~$ cat .xinitrc 
xrandr --setprovideroutputsource modesetting NVIDIA-0
xrandr --auto
exec enlightenment_start

If you use a login manager, you need to make sure that both xrandr options are run at the login manager (so a .xinitrc is not sufficient). Here’s an example for lightdm:


My favorite login manager is SLiM it’s pretty lightweight and fast, though I just noticed that it is probably not developed anymore. So, let’s use lightdm. Because you need to set the xrandr options when X starts, putting it into a .xinitrc (like above) will only work if you do use startx it does not work if you do use a login manager.

With lightdm, just edit /etc/lightdm/lightdm.conf and add the following after [Seat:*]

greeter-setup-script = /usr/bin/xrandr --auto
display-setup-script = /usr/bin/xrandr --setprovideroutputsource modesetting NVIDIA-0

That’s it.

intel+nvidia hybrid using bumblebee / optirun / primusrun

Finally I got it working. The freezes stop once you set:

GRUB_CMDLINE_LINUX="acpi_osi=! acpi_osi=\"Windows 2009\""

Obviously if you followed this article you’ll now have to remove /etc/X11/xorg.conf and revert your modifications to /etc/lightdm/lightdm.conf and you need to remove /home/yourusername/.xinitrc.

So I’ve just installed bumblebee-nvidia, added the above to /etc/default/grub, rebooted and I can successfully run optirun nvidia-settings -c :8 as well as primusrun glxgears and optirun glxgears. While running glxgears checking /proc/acpi/bbswitch returns ON else OFF. I also installed xserver-xorg-input-mouse because bumblebee gives warnings about the mouse module not being there (well I’ll need that anyway probably). My /etc/bumblebee/xorg.conf.nvidia looks like this:

Section "ServerLayout"
    Identifier  "Layout0"
    Option      "AutoAddDevices" "false"
    Option      "AutoAddGPU" "false"
# you can most likely remove this section
Section "Module"
    Load "modesetting"
Section "Device"
    Identifier     "Device0"
    Driver         "nvidia"
    BusID          "1:0:0"
    VendorName     "NVIDIA Corporation"
    Option "UseDisplayDevice" "none"

Features / Hardware / Other stuff


Due to the switch to intel graphics (due to bumblebee) Enlightenment did not properly set the backlight anymore. A fix for that was just adding a xorg.conf with the following contents:

Section "Device"
    Identifier  "Card0"
    Driver      "intel"
    Option      "Backlight"  "intel_backlight"


I’ve got the following two packages installed: xserver-xorg-input-libinput xserver-xorg-input-evdev. mouse click by tapping on the touchpad did not work, for that I just applied a configuration file which I did find in the archlinux wiki:

root@asuna:/home/jean# cat /etc/X11/xorg.conf.d/10-synaptics.conf 
Section "InputClass"
        Identifier      "Touchpad"                      # required
        MatchIsTouchpad "yes"                           # required
        Driver          "synaptics"                     # required
        Option          "MinSpeed"              "0.5"
        Option          "MaxSpeed"              "1.0"
        Option          "AccelFactor"           "0.075"
        Option          "TapButton1"            "1"
        Option          "TapButton2"            "2"     # multitouch
        Option          "TapButton3"            "3"     # multitouch
        Option          "VertTwoFingerScroll"   "1"     # multitouch
        Option          "HorizTwoFingerScroll"  "1"     # multitouch
        Option          "VertEdgeScroll"        "1"
        Option          "CoastingSpeed"         "8"
        Option          "CornerCoasting"        "1"
        Option          "CircularScrolling"     "1"
        Option          "CircScrollTrigger"     "7"
        Option          "EdgeMotionUseAlways"   "1"
        Option          "LBCornerButton"        "8"     # browser "back" btn
        Option          "RBCornerButton"        "9"     # browser "forward" btn

But that still did not make it working, I added the following one (and honestly I do not remember where I did find it – Most likely in the archlinux wiki as well – please drop me a note in case you know it)

root@asuna:/home/jean# cat /etc/X11/xorg.conf.d/40-libinput.conf 
Section "InputClass"
        Identifier "libinput touchpad catchall"
        MatchIsTouchpad "on"
        MatchDevicePath "/dev/input/event*"
        Driver "libinput"
        Option "Tapping" "on"

which did make it work :^)

HP Freefall Protection / hdapsd

The HP OMEN does have an accelerometer and hpsad detects if your notebook is free-falling. If this happens, the heads are parked to not cause any damage to the harddisc. This is a pretty useful feature and should generally be enabled. I noticed that the default of 15 is quite sensitive and a value of 100 works identically. Letting it fall carefully in 20cm height is still detected. I’ve just installed hdapsd (no reboot was required) stopped it using systemctl stop hdapsd started it manually using hdapsd -d sda -s 100 even with a value of 1000 fast lifting up of the notebook causes the head parking:

root@asuna:~# hdapsd -d sda -s 200
Sun Apr  1 15:14:54 2018: Starting hdapsd
Sun Apr  1 15:14:54 2018: Selected interface: FREEFALL
Sun Apr  1 15:14:54 2018: Uses hardware logic from /dev/freefall
Sun Apr  1 15:14:57 2018: parking
Sun Apr  1 15:14:58 2018: un-parking
Sun Apr  1 15:14:59 2018: parking
Sun Apr  1 15:15:00 2018: un-parking

I’ve modified the configuration file /etc/hdapsd.conf to look like this:

# Which device(s) should be protected by hdapsd?
# Can be either a single string (one device):
# Or an array of strings (multiple devices):
#  device=["sda", "sdb"];
# Will be autodetected if not set.
# How sensitive should hdapsd be? Defaults to 15.
# You probably want to change this.
# Enables adaptive mode, where hdapsd adjusts the sensitity
# while the mouse and keyboard are used.
# You probably want to enable this.
# Run hdapsd in background as a daemon.
#  background=true;
# Write a pid file.
#  pidfile="/var/run/";
# Enable logging to syslog.
#  syslog=true;

Since it doesn’t matter what sensitivity I do set, I just used 200.



I did set up bcache afterwards; for that purpose I was moving files around, sorted/resized partitions. In the end I created a 128 GB partition on the NVMe which I do use as caching-device:

root@asuna:~# make-bcache -C /dev/nvme0n1p6

The tricky part was growing bcache. Actually it is simple if you make sure it does start at the same sector – don’t be confused that I do use „sda3“ – sda3 did start at sector 2048. I just created /dev/sda3 as bcache-backing:

root@asuna:~# make-bcache -B /dev/sda3

Using bcache-super-show I retrieved the cache uuid so that I was able to attach it:

root@asuna:~# bcache-super-show /dev/nvme0n1p6 | grep cset
cset.uuid               defcbf57-d360-44ee-8d85-bf9f817dd19e
root@asuna:~# echo defcbf57-d360-44ee-8d85-bf9f817dd19e > /sys/block/bcache0/bcache/attach

Created a filesystem:

mkfs.ext4 -O metadata_csum,64bit /dev/bcache0

Moved my files from oldhome (non bcache) to newhome (bcache) using cp, added it using the uuid output of blkid to /etc/fstab, deleted both partitions, re-created the partition starting at sector 2048, reboot, resize2fs /dev/bcache0 … Done. Bcache will help to make a lot more use of the NVMe in this system.


I just replaced BATT_HD_POWERMGMT=1 with BATT_HD_POWERMGMT=200 in /etc/laptop-mode/laptop-mode.conf.

Intel graphics / GuC firmware

I noticed GuC firmware load skipped in dmesg. Added the following:

options i915 enable_guc_loading=1 enable_guc_submission=1

and it’s there, too.

Probably useful to know

Bumblebee Slow?

You might test your FPS using glxgears and notice that you’re only getting like 60 fps:

jean@asuna:~$ primusrun glxgears
/usr/bin/primusrun: line 41: warning: command substitution: ignored null byte in input
294 frames in 5.0 seconds = 58.782 FPS
301 frames in 5.0 seconds = 60.053 FPS
301 frames in 5.0 seconds = 60.056 FPS

While glxgears is no benchmarking tool – the above a really low fps for the GTX 1050 Ti. Well, this is vblank synchronization in action as the primus FAQ states:

jean@asuna:~$ vblank_mode=0 primusrun glxgears
/usr/bin/primusrun: line 41: warning: command substitution: ignored null byte in input
ATTENTION: default value of option vblank_mode overridden by environment.
ATTENTION: default value of option vblank_mode overridden by environment.
ATTENTION: default value of option vblank_mode overridden by environment.
ATTENTION: default value of option vblank_mode overridden by environment.
13118 frames in 5.0 seconds = 2623.527 FPS
14472 frames in 5.0 seconds = 2894.247 FPS
14328 frames in 5.0 seconds = 2865.422 FPS

So, errm. Don’t worry. Interestingly, I’m getting more FPS with bumblebee than without regardless of vblank_mode in Unigine. Interestingly, the battery shows 8 hours remaining when using the intel gpu instead of nvidia – with nvidia it’s showing 4 hours. Though, really, I haven’t tested how long the battery holds.

Repairing EFI-Bootloader

I really don’t know which of my tasks caused that – at some stage after a reboot I was presented with the grub-rescue menu. Fixing was simple, though.

In grub rescue I used ls to get a list of disks and partitions, I manually checked for the disk containing /boot. Found it by typing ls (hd1,gpt4)/ I believe. Now I told grub rescue where to find grub by issuing:

# this WILL be different on your system
set prefix=(hd1,gpt4)/boot/grub

Now I told grub rescue about root.

set root=(hd1,gpt4)

And finally I made it boot/start the bootloader

insmod linux
insmod normal

Back in my shiny debian I repaired the bootloader by issuing:

apt-get install --reinstall grub-efi
# in case you got an NVMe as I do and you do boot from it, if not this command WILL be different
grub-install /dev/nvme0n1


root@asuna:~# efibootmgr --verbose | grep debian
