Public bug reported: [Impact] In Dell platform OLED machine with eDP 1.5, monitor's brightness won't change when pressing brightness key F6/F7.
[Fix] Cherry-pick the following patchset which has already landed in linux-next: https://patchwork.freedesktop.org/series/143910/#rev3 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). ** Affects: linux (Ubuntu) Importance: Undecided Status: New ** Affects: linux-oem-6.11 (Ubuntu) Importance: Undecided Status: New ** Affects: linux (Ubuntu Noble) Importance: Undecided Status: Invalid ** Affects: linux-oem-6.11 (Ubuntu Noble) Importance: Undecided Status: New ** Also affects: linux-oem-6.11 (Ubuntu) Importance: Undecided Status: New ** Also affects: linux (Ubuntu Noble) Importance: Undecided Status: New ** Also affects: linux-oem-6.11 (Ubuntu Noble) Importance: Undecided Status: New ** Changed in: linux (Ubuntu Noble) Status: New => Invalid -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/2097818 Title: OLED panel screen backlight brightness does not change with brightness hotkey(F6&F7 Key) Status in linux package in Ubuntu: New Status in linux-oem-6.11 package in Ubuntu: New Status in linux source package in Noble: Invalid Status in linux-oem-6.11 source package in Noble: New Bug description: [Impact] In Dell platform OLED machine with eDP 1.5, monitor's brightness won't change when pressing brightness key F6/F7.
