Brightness

For me on kernel 6.6 brightness settings did not work unless I removed the recommended acpi_backlight=vendor option so this option may no longer be required.

Kernel sources

To Striber , I want to let you know that sys-kernel/gentoo-sources does not change the video code in any way. It is exactly the same as sys-kernel/vanilla-sources. Please do not suggest one over the other. It is valid that a minimum kernel version is required. Thanks. --Grknight (talk) 12:48, 28 August 2019 (UTC)

To Author, thank you, very good wiki. On my T495s the iw ucode dosen't work (but is not needed) (europe version-Wireless-AC 9260 [8086:2526] (rev 29)). There is a problem reported to 'kfd' (kfd kfd: Error initializing iommuv2) - but /sys/kernel/iommu_groups/* shows IOMMU Group 1: 05:00.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc.

It does not look like there is anything to discuss here (concerning documentation). If you need support, please see https://www.gentoo.org/support/ --Maffblaster (talk) 22:47, 14 February 2022 (UTC)
