Public bug reported: After switching to Ubuntu 15.10, my miniDisplay port adapter doesn't work anymore, or in rare cases , it works, but it gives a maximum resolution of 1024x768 (whereas the monitor is 1920x1080). Also, when I connect my iphone5 I cannot use the USB tethering anymore. If I boot with the older kernel, everything works as expected.
