I can confirm that the fix resolves the original backlight issue on my hardware.
Verification details: - Machine: HP Pavilion x360 Convertible 14-ba0xx - GPU: Intel HD Graphics 610 [8086:5906] - Ubuntu: 24.04 (Noble), amd64 - Running kernel: 7.0.0-31-generic - Package version: 7.0.0-31.31~24.04.1 Brightness hotkeys and the GNOME brightness slider now change the physical panel brightness normally. The original failure was reproducible with 7.0.0-28-generic, where the software brightness value changed but the physical backlight stayed dim. No i915.enable_dpcd_backlight workaround is present on the current kernel command line. This verifies the Noble generic/HWE kernel fix for my duplicate report #2163014. The linux-xuantie verification request does not apply to this amd64 machine. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2161309 Title: Backlight regression To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2161309/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
