Same problem with Legion 5 pro, 5800H+3070. Tried config https://www.reddit.com/r/GamingLaptops/comments/ls9k5r/legion_5_pro_other_info_64gb_ram_upgrade_linux/
This guy claims that after 'upgrading to Kernel 5.10', 'Blacklisting noveau drivers', 'changing the .conf file' and 'adding modules in initramfs', brightness control works. https://www.notion.so/Legion-5 -Pro-Regolith-Important-Steps-2c468d1b33cc481dbd92d5ea59a6b74b Will try this later. So far I have tried changing .conf and adding modules in initramfs and it didn't work. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1905591 Title: no brightness control in {455,460} after update from 450 To manage notifications about this bug go to: https://bugs.launchpad.net/oem-priority/+bug/1905591/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
