Luckily, this is easy enough to modify, as long as the kernel version is >= 3.13.x and < 4.2. If it is, or when the brightness buttons are working, the issue is that the kernel can not detect where the brightness control is located. īrightness does not change with keyboard shortcutsįirst, make sure vendor compatibility is on in the kernel configuration. Kernel with version 4.2 or newer is needed with some 8th generation chipsets.This is usually done through the bootloader. acpi_osi='Linux' can be passed to the kernel command line to try to solve this kind of issue. Otherwise, it is possible to always have a black screen unless nomodeset is passed to the kernel, thus disabling kernel mode setting (KMS). According to this Debian wiki, CONFIG_FRAMEBUFFER_CONSOLE must be set to y (aka built-in to the kernel).Section 'Device' Identifier 'Device0' Driver 'intel' Option 'AccelMethod' 'SNA' Option 'TearFree' 'true' EndSection Or by grepping the MODULE_FIRMWARE in kernel source tree: Kernel: HuC: Failed to fetch firmware i915/kbl_huc_ver01_07_1398.bin (error -2) Kernel: GuC: Failed to fetch firmware i915/kbl_guc_ver9_33.bin (error -2) To identify the firmware file name, either by checking /var/log/kern.log: Enabling GuC/HuC firmware loading could cause issues on some systems, disable it if you experience freezing (for example, after resuming from hibernation). HuC firmware (and GuC as a dependent) is needed for AVC/HEVC/VP9 low power encoding bitrate control, including CBR, VBR, etc. HD-CAMERA (super clear) BUILT-In Speaker,BUILT-In Mic BUILT in Card Reader. Including the firmware in-kernel may cause suspend-to-ram to fail, if this is a concern don't include the blob built into the kernel, instead, add the firmware blob into the initramfs.įor Gen11+ GPUs, GuC/HuC firmware are loaded by default since Linux 5.4 (see commit).įor Gen9 and Gen9.5 GPUs, GuC/HuC firmware won't be loaded by default, it is possible to enable loading of the firmware using kernel parameter i915.enable_guc_loading=1 (prior to kernel 4.16) or i915.enable_guc=3 (since kernel 4.16).
