Install Linux Desktop Environment

The ECI core images core-bullseye and core-jammy do not have a graphical desktop environment installed by default, neither do minimal or server variants of Debian* or Canonical Ubuntu*.

To install a graphical desktop environment on your system, do the following:

1. Setup the ECI APT repository.

2. Install the desktop environment Deb packages and dependencies. Run the following commands, replacing the <environment> placeholder with one of the Desktop Environments listed in the following table.

   $ export DEBIAN_FRONTEND=noninteractive
   $ sudo -E apt install task-desktop task-<environment>-desktop
   

   Package	Description
   task-mate-desktop	Installs the MATE Desktop
   task-gnome-desktop	Installs the GNOME Desktop
   task-xfce-desktop	Installs the XFCE Desktop
   task-lxde-desktop	Installs the LXDE Desktop
   task-cinnamon-desktop	Installs the Cinnamon Desktop
   task-kde-desktop	Installs the KDE Desktop

3. The desktop environment should start automatically after rebooting the system:

   $ sudo reboot
   

Enable GuC/HuC Firmware Loading

From Gen 9th Intel® Graphics (Skylake and later), Intel® introduced Graphics microcontroller (GuC) and HEVC/H.265 microcontroller (HuC), which provide the following functionalities:

• Offloading some media decoding functionality from the CPU to HuC (only applicable if using Intel® media driver for hardware video acceleration).

• Low-level graphics context scheduling and context submission (GuC submission).

• Tracking business and making frequency and power gating decisions while scheduling.

To use this functionality, the GuC or HuC firmware must be loaded by setting the kernel module parameters:

i915 Kernel Module Parameters	Description
enable_guc=1	GuC submission and power management
enable_guc=2	HuC authentication only
enable_guc=3	Combine HuC and GuC
enable_guc=7	Combine HuC and GuC and SR-IOV PF mode support ONLY available for i915/*_guc_70.0.3.bin and i915/*_huc_7.9.3.bin on Intel® firmware mentioned here for 11th Gen Intel® Core™ U-Series processors and 11th Gen Intel® Core™ P-Series processors [Tiger Lake] and 12th Gen Intel® Core™ S-Series processors and 12th Gen Intel® Core™ P-Series processors [Alder Lake]

For more details, refer to Intel® Graphics for Linux* and Linux gpu/i915.

1. Setup the ECI APT repository.

2. Install one of the available ECI Linux kernels. For this example, we installed linux-image-intel-rt:

   $ sudo apt install linux-image-intel-rt
   

   $ apt-cache search linux-image-intel | grep -v dbg
   linux-image-intel-acrn-sos - intel-acrn-sos Linux kernel, version 5.10.140-linux-intel-acrn-sos+
   linux-image-intel-rt - intel-rt Linux kernel, version 5.10.140-rt73-intel-ese-standard-lts-rt+
   linux-image-intel-xenomai - intel-xenomai Linux kernel, version 5.10.140-intel-ese-standard-lts-dovetail+
   

3. Install GuC and HuC Linux firmware available from the ECI APT repository to follow both the official Linux distribution package release and Out-of-Tree (OOT) SR-IOV Physical Function (PF) mode support.

   Debian* 11 (Bullseye)Canonical Ubuntu* 22.04 (Jammy Jellyfish)

   $ sudo apt install firmware-misc-nonfree firmware-linux
   

   For example, on Debian* 11 (Bullseye) distribution, using the ECI APT repository should display:

   $ sudo apt-cache policy firmware-misc-nonfree
   firmware-misc-nonfree:
   Installed: 20230210-4-intel-iotg
   Candidate: 20230210-4-intel-iotg
   Version table:
   *** 20230210-4-intel-iotg 1000
         1000 https://eci.intel.com/repos/bullseye isar/main amd64 Packages
         100 /var/lib/dpkg/status
      20210315-3 500
         500 http://deb.debian.org/debian bullseye/non-free amd64 Packages
   

4. Enable GuC/HuC firmware loading by adding the i915 kernel module input parameter:

   $ echo "options i915 enable_guc=3" | sudo tee -a /etc/modprobe.d/i915.conf
   

5. After the installation is complete, reboot the system:

   $ sudo reboot
   

   When the system reboots, Intel® Graphics HuC / GuC should be enabled.

   

   Verify that the GuC / HuC modules are enabled:

   $ dmesg | grep i915
   

   ...
