I tried using the following kernel as suggested from this link; http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.3-wily/
http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.3-wily/linux- headers-4.3.0-040300-generic_4.3.0-040300.201511020949_amd64.deb http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.3-wily/linux- image-4.3.0-040300-generic_4.3.0-040300.201511020949_amd64.deb This resulted in a unbootable system, so used a previous kernel from Ubuntu menu and then removed the offending kernel image. Also i am using propriety Nvidia drivers, so that could be a cause as the kernel failed to install properly . Preparing to install an upstream kernel First, if one is using select proprietary or out-of-tree modules (ex. vitualbox, nvidia, fglrx, bcmwl, etc.) unless there is an extra package available for the version you are testing, you will need to uninstall the module first, in order to test the mainline kernel. If you do not uninstall these modules first, then the upstream kernel more than likely will not boot. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1516025 Title: Realtek ALC3661 Alienware14 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1516025/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
