I have tested the fix on my Dell Latitude 7490 running Ubuntu 24.04. Hardware:
* Dell Latitude 7490 * Intel UHD Graphics 620 Kernel tested: * 7.0.0-34-generic Results: * Brightness keys work correctly. * GNOME brightness slider works correctly. * The physical display brightness changes as expected. * No `i915.enable_dpcd_backlight=0` kernel parameter is used. * Suspend/resume works correctly, both when suspending from Ubuntu and using the keyboard. * Brightness continues to work correctly after resume. * A full reboot also works correctly. I can confirm that the backlight regression is fixed on my Dell Latitude 7490 with 7.0.0-34-generic. Thank you for fixing this issue. -- 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
