Hi guys, I have tested the proposed kernel on my system and can confirm that the regression is fixed.
Hardware & System Details: - Device: Dell Precision M4800 - OS: Ubuntu 26.04 LTS - Graphics: Hybrid / Dual GPU (Intel HD Graphics + NVIDIA Quadro K1100M on nouveau) - Tested Kernel Version: linux-image-7.0.0-31-generic (7.0.0-31.31) from -proposed Test Results: 1. Backlight / Brightness Regulation: Works properly via Fn keyboard shortcuts as well as the GUI slider. 2. Suspend & Resume: The black screen issue is completely resolved. Upon waking from suspend, the screen backlight turns back on immediately. Thank you for fixing this issue! ***** PS, Just as an aside note: AI was very helpful - guide how to install linux-image-7.0.0-31-generic https://aistudio.google.com/ 2 minutes for me -- 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
