============================================================== Ubuntu Desktop Certified Hardware Coverage for 18.04 LTS OSP1 ============================================================== .. Subtitle=Version 1.0 Introduction ------------ The Ubuntu Certification team is continuously revisiting the scope of the tests comprising the Ubuntu Certified programme which is reviewed every six months, following the same Ubuntu cadence for point releases on Long Term Support releases. This review of new tests is performed during Ubuntu's development cycle and it never affects already released versions of Ubuntu. This document lists the coverage for certification of Ubuntu Desktop 18.04 LTS. This coverage will remain as it is for Ubuntu Desktop 18.04 LTS through the life cycle of Ubuntu Desktop 18.04 LTS. .. include:: ../reuse/include.txt :start-after: .. :end-before: .. Blocking -------- Firmware ~~~~~~~~ Ubuntu 18.04 LTS OSP1 is installed using the factory default BIOS or UEFI, with the default options (including SecureBoot, if that's the default setting). Firmware needs to be compliant with Canonical Firmware Test Suite (FWTS). It is recommended that after running Canonical fwts with the list of tests defined in the `Appendix A <#appendix-a-fwts-tests-18ops>`__, ideally, no CRITICAL or HIGH failures should be reported, but those are not automatically certification blockers. Systems supporting fwupd will undergo firmware update testing when newer firmwares are available to the system, to ensure that users can upgrade their firmware without issue. During the maintenance phase, firmware updates will be tested on a regular cadence. Processors ~~~~~~~~~~ x86_64 and ARM processors are tested to ensure proper functionality. We will test specific features as: - CPU's performance states (frequency up and down in runtime) - CPU's sleep states (cpu on and off in runtime) - Running CPU at its maximum frequency We will also include a general stress test performed for 120 minutes to verify that the system can handle a sustained high load for a period of time. This test uses the tool “stress-ng” available in the Universe repositories. In addition, for Intel devices, IPDT (Intel Processor Diagnostic Tools) test suite will be run, ensuring power management works as designed. Memory ~~~~~~ Proper detection of the amount of memory installed is required (the amount of memory installed is the memory seen by the OS). Internal Hard Drives ~~~~~~~~~~~~~~~~~~~~ All internal hard drives are tested to be properly detected. On all of them, an in-house performance test is run. All disks need to report at least a read performance of 15MB/s. The following types of internal storage are currently supported/tested: - PCIe NVMe SSD - SATA SSD/HDD Optical Drives ~~~~~~~~~~~~~~ Optical drives are tested for read/write based on specifications of the optical unit. Depending on the unit theoretical feature support, we will test: - CD read capabilities (data only) - CD write capabilities - DVD read capabilities (data only) - DVD write capabilities - Bluray-disc read capabilities (data only) - Bluray-disc write capabilities Graphics ~~~~~~~~ The ability to run the desktop environment out of the box is required. When certifying, stock Ubuntu open source drivers need to work to complete the installation of Ubuntu, although proprietary drivers are accepted, if they are installable through Ubuntu Drivers. **Laptops** - The integrated display is tested with its highest resolution. At its highest resolution, the image should look clean, without any type of corruption. - Each of available external video ports (currently supported: HDMI, DisplayPort, Mini Displayport, Thunderbolt 3) are tested one by one. Hot plugging and different modes (mirror, extended, just internal, just external) are required to work. If several external ports are available, they are not required (nor tested) to work simultaneously. - Display brightness. It should be possible to dim the brightness of the internal display. - The system must support Gnome Shell 3.28 and basic 3D rendering. - Hybrid graphics: - On systems with Hybrid graphics, features described above need to work with both Performance and Power Saving mode. - On systems with an integrated and a NVIDIA discrete GPU users should be able to choose between a performance profile (discrete GPU is used to accelerate rendering) and a power saving profile (discrete GPU is switched off to save battery). - On systems with an integrated and an AMD discrete GPU users should be able to run graphics workloads in the discrete GPU. - On systems with a NVIDIA hybrid graphics, monitor hotplugging needs to work for all external graphics ports when system is in Performance mode. When the system is in Power Saving mode, external display is not required to work on the ports that are only physically connected to the discrete GPU. **Desktops with an integrated display (aka All-In-Ones)** - The integrated display is tested with its highest resolution. At its highest resolution, the image should look clean, without any type of corruption. - The integrated display must support basic 3D rendering. - The system must support display rotation (0°, 90°, 180°, 270°) - Each of available external video ports (currently supported HDMI, DisplayPort, Mini Displayport, Thunderbolt 3 are tested one by one. Different modes (mirror, extended, just internal, just external) are required to work. If several external ports are available, they are not required (nor tested) to work simultaneously. **Desktops without an integrated display** - Each of available external video ports (currently supported HDMI, DisplayPort, VGA, DVI, S-Video, RCA) are tested one by one, at their highest resolution. Different modes (mirror, extended, just internal, just external) are required to work. - If several external ports are available, no matter how many ports are designed to work synchronously on the graphic controller, only two of them (regardless the combination) are supported simultaneously (dual-head), unless the hardware does not support two monitors setup. - If the system contains both an integrated and a discrete GPU, only the discrete GPU is supported - The system must support Gnome Shell 3.28 and basic 3D rendering. - The system must support display rotation (0°, 90°, 180°, 270°) - Desktops with multiple discrete GPUs are not supported; we only support one discrete GPU, as above. **Convertible Laptops (aka 2-in-1s)** - The system must support display rotation (0°, 90°, 180°, 270°) - The desktop environment must rotate automatically when sensors detect a rotation Audio ~~~~~ Output sound needs to be undistorted between 0%-100%.

The test is passed if all 30 cycles complete without failure. Any errors reported in the fwts log for the 30 cycle suspend/resume stress test are informational only and do not affect the outcome of the test, however, we do recommend examining and fixing any failures noted, as they indicate firmware non-compliance with standards. Apart from the stress test, a single cycle suspend/resume is performed, if it's a hybrid graphic system, suspend and graphic related functionalities are required to work flawlessly on both Performance mode and Power Saving mode, and the following features and devices are tested and need to work after suspend: - CPU - Memory - Networking (Wifi, Ethernet) - Audio - Bluetooth - Display resolutions should be consistent before and after suspend - USB controllers - Input devices - Mediacards **Boot/Reboot** Both cold boot and soft boot are tested and required to work.
