** Description changed: I have Dell G15 5515 Ryzen edition. It has Nvidia 3050 graphics. In /sys/class/backlight directory, there are two directories amdgpu_bl0 and nvidia_wmi_ec_backlight. When I change the screen brightness via slider then it changes the brightness value of nvidia_wmi_ec_backlight but it doesn't work. When I manually changed the value of amdgpu_bl0 brightness file then my screen brightness changed. - My BIOS is updated to the latest version and I have NVIDIA Driver with - version 510.73.05. + My BIOS is updated to the latest version and I have NVIDIA Driver with version 510.73.05. + --- + ProblemType: Bug + ApportVersion: 2.20.11-0ubuntu82.1 + Architecture: amd64 + AudioDevicesInUse: + USER PID ACCESS COMMAND + /dev/snd/controlC2: yorozuya 2677 F.... pulseaudio + /dev/snd/controlC0: yorozuya 2677 F.... pulseaudio + /dev/snd/controlC1: yorozuya 2677 F.... pulseaudio + /dev/snd/controlC3: yorozuya 2677 F.... pulseaudio + CRDA: N/A + CasperMD5CheckResult: pass + CurrentDesktop: ubuntu:GNOME + DistroRelease: Ubuntu 22.04 + InstallationDate: Installed on 2022-05-30 (2 days ago) + InstallationMedia: Ubuntu 22.04 LTS "Jammy Jellyfish" - Release amd64 (20220419) + MachineType: Dell Inc.
