First, make sure 4.11 is working. I can build kernel for you, but it will take a dozen iterations.
It can be much faster if you build your own kernel locally, $ sudo apt install git $ sudo apt build-dep linux $ git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git $ cd linux $ git bisect start $ git bisect good v4.11 $ git bisect bad v4.12-rc1 $ make localmodconfig $ make -j`nproc` deb-pkg Install the newly built kernel. If the issue still happens, $ git bisect bad ...otherwise, $ git bisect good Repeat to "make -j`nproc` deb-pkg" until you find the commit that causes the regression. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1722478 Title: Two-finger scrolling no longer works after resuming from suspend To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1722478/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
