I compiled several Ubuntu-5.13.0-x.x tags from https://kernel.ubuntu.com/git/ubuntu/ubuntu-impish.git/refs/ but the backlight issue seems to go far back in time. I tested: - Ubuntu-5.13.0-25.26 - Ubuntu-5.13.0-21.21 - Ubuntu-5.13.0-20.20 - Ubuntu-5.13.0-19.19 - Ubuntu-5.13.0-16.16
In Ubuntu-5.13.0-16.16, there are some 400ish commits by Ubuntu on top of upstream v5.13.13. I haven't been able to identify which could be responsible, yet. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1954843 Title: amdgpu_bl0: Failed to write system 'brightness' attribute: Invalid argument To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1954843/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
