This bug is awaiting verification that the linux-oem-6.11/6.11.0-1016.16 kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-noble-linux-oem-6.11' to 'verification-done- noble-linux-oem-6.11'. If the problem still exists, change the tag 'verification-needed-noble-linux-oem-6.11' to 'verification-failed- noble-linux-oem-6.11'.
If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

[Fix] Cherry-pick the following patchset which has already landed in linux-next: https://patchwork.freedesktop.org/series/143910/#rev3 which contains: 5dfc37a6b77b drm/dp: Add eDP 1.5 bit definition 9ee185564425 drm/dp: Increase eDP display control capability size 9535c6a4c61c drm/i915/backlight: Use proper interface based on eDP version 64481497924d drm/i915/backlight: Check Luminance based brightness control for VESA 3f8a009a794e drm/i915/backlight: Modify function to get VESA brightness in Nits b68074efcfcf drm/i915/backlight: Add function to change brightness in nits for VESA 8d502933ac20 drm/i915/backlight: Setup nits based luminance via VESA a5efc8dcfe71 drm/i915/backlight: Enable nits based luminance =============================================================================== Besides, there will be a prerequisite patch needed in order to clean-apply the above patchset: 6276706f33cc drm/i915/display: convert dp aux backlight to struct intel_display So there will be 9 patches in total. [Test Plan] 1. Boot up the Ubuntu OEM image 2. Wait until the screen shows the desktop 3. Press brightness keys (F6 or F7) and see if the brightness has changed. [Where problems could occur] May cause regression on some monitors which use the old brightness-changed path (PWM path).
