I spend some time, to get openSUSE Leap 16 up and running on my new HP Elitebook 840 G11 with my Dell U3425we Hub-Monitor.

Here are some hints for the installation:

• Reduce the Windows Partion to get space for Linux
  During the installation, I have not found a way to reduce the size of the Windows partition. Therefore I created the partition under Windows with Disk Management (diskmgmt.msc) Then you can choose the free partion during the installation via the Agama-Installer
  
  I installed openSUSE on nvme0n1p4 with action "Delete" and not "allow shrink"

• Install from USB stick
  

  To get into the BIOS, press ESC serveral times during startup

  Then choose "Boot Menu (F9)" from the BIOS menu. There choos your USB stick to install openSUSE

  I had to disable secure boot in the BIOS.

• WiFi works out of the box 😄

• Audio / Sound
  Does not work out of the box
  Install "sof-firmware"

• Mount Windows Partion
  If you see a yellow warning triangle on your windows drive like:
  
  Then your Bitlocker encryption is not complete. Just complete your Bitlocker encryption ¹. Now you cann access your Windows drive via Dolphin. You have to enter two passwords. The first one is the Bitlocker-Key and the second one is your password.
  If you do not need a Bitlocker encryption on your Windows Drive, you can decativate your Bitlocker encryption after the successfull encryption.

• Problems with Dockingstation (Dell Monitor U3425we)
  

  • Change Bios Settings

    • Disable FastBoot:
      After disabling FastBoot, I can use mouse and keyboard on the GRUB screen. Also the monitor speakers works after disabling FastBoot.

    • Boot on Power:
      If you want, that the Laptop boots, when you connect Thunderbold (Boot on Power) Disable "HP Powermangement" and enable "Boot on Power" in the BIOS ²

  • Change GRUB2 stetting

    • During the start up, no login screen after booting.
      Therefore, I had to enforce to usse the montior screen.

      First, get your display via
      

      xrandr --listmonitors 

      I get:
      

      0: +*eDP-1 2560/301x1600/188+0+0  eDP-1
      1: +DP-3 640/169x480/127+2560+0  DP-3

      DP-3 is my Dell monitor. With ":D" I force to use this monitor.
      Extend GRUB_CMDLINE_LINUX_DEFAULT with "video=DP-3:D video=eDP:e" in /etc/default/grub and generate the new grub config ³
      

      GRUB_CMDLINE_LINUX_DEFAULT="mitigations=auto quiet video=DP-3:D video=eDP-1:e security=selinux selinux=1"

  • Still open:
    

    • Login screen lauches only with the resolution of 640x480. But after login, I have my preferd resolution.

• Install GPU Driver
  
  If you have the supported hardware ⁴, you can install oneAPI.
  Here you find the information, how to install oneAPI ⁵.

  This documentation there is also a link, how to install the Client GPU driver for Ubuntu⁶
  In addition to this documentation, here are the related openSUSE Leap 16 Packages:

  Ubuntu 2022 Package	openSUSE Leap 16 Package	Comment
  libze-intel-gpu1	libze_intel_gpu1	-
  libze1	level-zero	-
  intel-opencl-icd	intel-opencl	-
  clinfo	clinfo	-

  
  

  Verifying the installation
  

  sudo clinfo | grep "Device Name"

  you should get:
  

  Device Name                                   Intel(R) Arc(TM) Graphics 
  Device Name                                   Intel(R) Core(TM) Ultra 7 155H 
  Device Name                                   Intel(R) Arc(TM) Graphics 
  Device Name                                   Intel(R) Arc(TM) Graphics 
  Device Name                                   Intel(R) Arc(TM) Graphics

• Install oneAPI

  Install oneAPI: see ⁵
  

  sudo zypper addrepo https://yum.repos.intel.com/oneapi oneAPI
  
  rpm --import https://yum.repos.intel.com/intel-gpg-keys/GPG-PUB-KEY-INTEL-SW-PRODUCTS.PUB
  
  sudo zypper install intel-basekit

  oneAPI (version 2025.2) needs about 10GB disc space.

• Pytorch

  For Pytorch you need in addtion these following packages:

  Ubuntu 2022 Package	openSUSE Leap 16 Package	Comment
  libze-dev	level-zero-devel	-
  python3-dev	python313-devel	Python.h

  
  

  These packages are needed, if you want to use torch.compile ^{7 8}.
  

  For Pytorch you need the Deep Learning Essentials from oneAPI ⁹
  Check you oneAPI version and instal the corresponding version. In my case 2025.2

  sudo zypper install intel-deep-learning-essentials-2025.2

  Then you can follow the instruction in ¹⁰ and install pytorch

  pip3 install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/xpu
