Description: Ubuntu 24.04 LTS Release: 24.04 dell-uart-backlight kernel driver isn't in the 24.04 distribution, so NO Dell AIO display backlights can be adjusted. No brightness slider appears. (dell-uart-backlight is in the 23.10 distribution, but backlight/brightness slider control doesn't work 100% properly). Works fine in 23.04. ls -alR /lib/modules/6.5.0-35-generic/ | grep dell -rw-r--r-- 1 root root 13689 Apr 26 02:32 dell-smm-hwmon.ko.zst drwxr-xr-x 3 root root 4096 May 15 19:10 dell /lib/modules/6.5.0-35-generic/kernel/drivers/platform/x86/dell: -rw-r--r-- 1 root root 18647 Apr 26 02:32 dell-laptop.ko.zst -rw-r--r-- 1 root root 6158 Apr 26 02:32 dell-rbtn.ko.zst -rw-r--r-- 1 root root 8431 Apr 26 02:32 dell_rbu.ko.zst -rw-r--r-- 1 root root 13963 Apr 26 02:32 dell-smbios.ko.zst -rw-r--r-- 1 root root 4432 Apr 26 02:32 dell-smo8800.ko.zst -rw-r--r-- 1 root root 7762 Apr 26 02:32 dell-uart-backlight.ko.zst -rw-r--r-- 1 root root 3799 Apr 26 02:32 dell-wmi-aio.ko.zst -rw-r--r-- 1 root root 9209 Apr 26 02:32 dell-wmi-ddv.ko.zst -rw-r--r-- 1 root root 4532 Apr 26 02:32 dell-wmi-descriptor.ko.zst -rw-r--r-- 1 root root 11198 Apr 26 02:32 dell-wmi.ko.zst -rw-r--r-- 1 root root 3115 Apr 26 02:32 dell-wmi-led.ko.zst drwxr-xr-x 2 root root 4096 May 15 19:10 dell-wmi-sysman /lib/modules/6.5.0-35-generic/kernel/drivers/platform/x86/dell/dell-wmi-sysman: -rw-r--r-- 1 root root 18312 Apr 26 02:32 dell-wmi-sysman.ko.zst ls -alR /lib/modules/6.8.0-31-generic/ | grep dell -rw-r--r-- 1 root root 15140 Apr 19 14:46 dell-smm-hwmon.ko.zst drwxr-xr-x 3 root root 4096 May 25 10:15 dell /lib/modules/6.8.0-31-generic/kernel/drivers/platform/x86/dell: -rw-r--r-- 1 root root 18629 Apr 19 14:46 dell-laptop.ko.zst -rw-r--r-- 1 root root 6180 Apr 19 14:46 dell-rbtn.ko.zst -rw-r--r-- 1 root root 8582 Apr 19 14:46 dell_rbu.ko.zst -rw-r--r-- 1 root root 14726 Apr 19 14:46 dell-smbios.ko.zst -rw-r--r-- 1 root root 4433 Apr 19 14:46 dell-smo8800.ko.zst -rw-r--r-- 1 root root 3790 Apr 19 14:46 dell-wmi-aio.ko.zst -rw-r--r-- 1 root root 9166 Apr 19 14:46 dell-wmi-ddv.ko.zst -rw-r--r-- 1 root root 4492 Apr 19 14:46 dell-wmi-descriptor.ko.zst -rw-r--r-- 1 root root 11306 Apr 19 14:46 dell-wmi.ko.zst -rw-r--r-- 1 root root 3108 Apr 19 14:46 dell-wmi-led.ko.zst drwxr-xr-x 2 root root 4096 May 25 10:15 dell-wmi-sysman /lib/modules/6.8.0-31-generic/kernel/drivers/platform/x86/dell/dell-wmi-sysman: -rw-r--r-- 1 root root 18307 Apr 19 14:46 dell-wmi-sysman.ko.zst dup: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2067497 ProblemType: Bug DistroRelease: Ubuntu 24.04 Package: linux-image-6.8.0-31-generic 6.8.0-31.31 ProcVersionSignature: Ubuntu 6.8.0-31.31-generic 6.8.1 Uname: Linux 6.8.0-31-generic x86_64 NonfreeKernelModules: nvidia_modeset nvidia ApportVersion: 2.28.1-0ubuntu3 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/seq: al 3689 F.... pipewire /dev/snd/controlC1: al 3696 F.... wireplumber /dev/snd/controlC0: al 3696 F.... wireplumber CasperMD5CheckResult: pass CurrentDesktop: ubuntu:GNOME Date: Wed May 29 08:32:16 2024 InstallationDate: Installed on 2021-09-25 (978 days ago) InstallationMedia: Ubuntu 21.04 "Hirsute Hippo" - Release amd64 (20210420) MachineType: Dell Inc.
