I experienced the bug with the following kernel: Linux XPS-13-9350 3.19.0-64-generic #72~14.04.1-Ubuntu SMP Fri Jun 24 17:59:48 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux
I downloaded all the deb files from your link and tried to install them, see http://paste.ubuntu.com/18442758/ but linux-tools failed. I did not understand why and rebooted anyway to try. After rebooting I think I still had the old kernel and standby got more broken. Closing the lid and then opening it did not switch the screen back on and I had to use the power button to switch the laptop off and on. It seems like the package manager could resolve these issues, see http://paste.ubuntu.com/18442801/ After that I tested with the new kernel Linux XPS-13-9350 3.19.0-64-generic #72 SMP Thu Jun 30 18:23:54 CST 2016 x86_64 x86_64 x86_64 GNU/Linux and I closed/opened the lid a few (4) times. The sound still works fine, but at least once the mouse pointer disappeared for me. I could still use the touchpad to move the cursor and click things, but the cursor was invisible so I did not know where the cursor was located. I will test more to see if that happens more often. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1595803 Title: [i915_bpo][SKL] Display core init/uninit updates Status in linux package in Ubuntu: In Progress Bug description: At the moment, our i915_bpo driver on Vivid (kernel version: Ubuntu-3.19.0-62.70) lacks certain patches which fix the display core init/uninit sequence esp. handling dmc firmware loading and runtime- pm.
