Hi, I have installed a Debian Jessie on a brand new HP 8570W and many things do not work. From what I googled I have inferred that most of the following problems come from a bad DSDT : -HD4000 chipset not detected nor used by the system -Fan control "peculiar' -control of light level of the screen not possible - no control of keyboard backlight
I have opened the DSDT file but I have no skills to correct errors thrown by iasl. I have tried to install nouveau and nvidia and bumblebee, bumblebeed never started and nouveau and nvidia drivers work without ability to hibernate. Any help will be greatly appreciated. The extraction of DSDT according to rules is attached to this report. Thanks for any help! ** Attachment added: "Hewlett-Packard-HP_EliteBook_8570w.tar.gz" https://bugs.launchpad.net/lpbugreporter/+bug/752542/+attachment/3929252/+files/Hewlett-Packard-HP_EliteBook_8570w.tar.gz -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/752542 Title: ACPI DSDT info To manage notifications about this bug go to: https://bugs.launchpad.net/bumblebee/+bug/752542/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
