Hi Timo, > No need to test further mainlines, the backports that work fine on trusty > kernel somehow broke here. I have the same problem (blank screen when booting my broadwell-based thinkpad) under trusty. My current work-around is to use the previous kernel 3.16.0-34, or, to boot with -36 in recovery mode and then choose 'resume normal boot' (which then goes through fine). Could it be that the backport is broken there too? Or is that a separate bug report? Thanks, Philipp
