Don't blame Canonical or Kernel developers. ACPI is very naughty and manufacturers like to keep it that way to avoid non-paid systems to run on them flawlessly, since they can't exploit it.
ACPI development is basically reverse-engineering and having one machine for each type (remember, there are many different Dell Studio 15") is simply impossible. If Dell, ATI, NVidia, Intel etc don't help, there's no way around it. -- Dell Studio 1555: cannot change display brightness after a while, other hotkeys and ACPI stuff begin to fail https://bugs.launchpad.net/bugs/392812 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
