Mario, how about trying with "acpi_backlight=vendor" and also "dell_laptop.backlight=0" (goal still being to leave only intel_backlight).
Please report what you end up with in /sys/class/backlight in that case, and then whether you still see the flicker when you adjust the intel_backlight/brightness value. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/954661 Title: backlight brightness not adjustable by default on Dell XPS 13 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/954661/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
