So I just checked by completely removing nvidia drivers, i.e. sudo apt purge nvidia-*
then booting into latest available kernel, which at the time of this comment was, Linux 7.0.0-29-generic (on (K)Ubuntu 26.04), the problem persists in: 7.0.0-28-generic, and 7.0.0-29-generic After reinstalling the proprietary drivers 580, and booting into 7.0.0-27-generic, the drivers are inactive but the brightness problem doesn't exist. Problems being: 1.) No brightness control when the display is working 2.) After resume from suspend, the backlight of the inbuilt display does-not switch-on. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2161309 Title: Backlight regression To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2161309/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
