The issue with the brightness slider not moving in the gnome panel menu, in response to brightness keys, was fixed after the latest round of updates that installed gnome-shell 3.36.

As per prev. comment, the test kernel re-enables the keyboard brightness setting. However, the slider in the Gnome panel menu is not being moved when using the keyboard keys. Dragging the slider with the mouse does change the brightness, though. (May be related: The volume slider in the panel menu & the volume keys show the same behaviour: the volume keys work but do not affect the slider) And by the way, the brightness problem also occurs on Asus Zenbook Flip UX561UD, and the test kernel behaves in the same way, keys work but slider unaffected. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1858844 Title: [Dell XPS 15 9575] Screen brightness stopped working with linux- image-5.4.0-9-generic To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1858844/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
