I've been using Ubuntu 26.04 daily build on my Dell 3585 and there is a bug causes my machine fail to boot. The system stuck at boot session with this following error message: boot micmute setting an led's brightness failed (-5) I've updated the system and sadly, the bug hasn't been solved. Luckily, I've found a quite simple solution from internet. sudo nano /etc/default/grub Add "module_blacklist=dell_laptop" parameter to the default grub parameter: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash module_blacklist=dell_laptop" Save the file, update grub: sudo update-grub Last, reboot your system.
