On supported Skylake and newer processors, some video features (e.g. CBR rate control on SKL low-power encoding mode) may require the use of an updated GPU firmware, which is loaded by default only on Gen 11+ hardware since Linux 5.4. Enabling GuC/HuC firmware loading can cause issues on some systems disable it if you experience freezing (for example, after resuming from hibernation). Note: You might need to add more device sections than the one listed above. You may need to indicate Option "AccelMethod" when creating a configuration file, the classical options are UXA, SNA (default) and BLT. pixelated graphics, corrupt text, etc.), try using UXA instead, which can be done by adding the following line to your configuration file: If you experience issues with default SNA (e.g. See the "AccelMethod" option under intel(4) § CONFIGURATION DETAILS. To check which options are currently enabled, run Some of the module options impact power saving.Ī list of all options along with short descriptions and default values can be generated with the following command: The i915 kernel module allows for configuration via module options. You will note that many options default to -1, resulting in per-chip powersaving defaults. It is however possible to configure more aggressive powersaving by using module options. Note: This parameter is enabled by default for Skylake and newer as well as Bay- and Cherry-Trail (VLV/CHV) since Linux 5.1. #INTEL HD GRAPHICS 4000 OPENGL 4.1 DRIVER#Įtc/modprobe.d/nf options i915 fastboot=1 Intel GVT-g graphics virtualization support To force enable fastboot on platforms where it is not the default already, set i915.fastboot=1 as kernel parameter or set in /etc/modprobe.d/nf: The goal of Intel Fastboot is to preserve the frame-buffer as setup by the BIOS or bootloader to avoid any flickering until Xorg has started.#INTEL HD GRAPHICS 4000 OPENGL 4.1 INSTALL#.#INTEL HD GRAPHICS 4000 OPENGL 4.1 HOW TO#.
