** Description changed: I tried running Ubuntu 20.04 (ISO downloaded on March 10th) on a Dell XPS 15 7590 with the 4k LED display (*not* OLED). The screen backlight control keys seem to be registered but the brightness remain unchanged. --- ProblemType: Bug ApportVersion: 2.20.11-0ubuntu20 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: ghislain 1632 F.... pulseaudio CurrentDesktop: ubuntu:GNOME DistroRelease: Ubuntu 20.04 InstallationDate: Installed on 2020-03-12 (0 days ago) InstallationMedia: Ubuntu 20.04 LTS "Focal Fossa" - Alpha amd64 (20200309) MachineType: Dell Inc.
