I actually switch back to my x230 and don't have the hardware for testing, but we should really bisect this issue so the current xenial kernel can be fixed. Anyone who wants to help can test those kernels https://wiki.ubuntu.com/Kernel/MainlineBuilds especially the late 4.4 and the early 4.5 i gue

@Hubert Of course it doesn't need a bisect when you already know the commit the fixes it :) But i would sugest that we try to get it fixed in xenial's kernel first. Unfortunately i can't assign the kernel team, can you help out here? ** Changed in: linux (Ubuntu) Status: Incomplete => Confi

@penalvch Thanks for the info, but can you assist us on how to test and get a fix in xenial's kernel. I am out of kernel packaging since 2.6.33 and want to help to make xenial working on Thinkpads with docking stations. -- You received this bug notification because you are a member of Kernel Pack

@penalvch I understand and would like to identify it, but unfortunately i can't trigger that bug on neither my x220 nor my x230 while all T450s should have problems with external display and docking stations. With linux-*-lts-* packages it will at least be resolved at least in autum :) -- You rec

@Christopher To demand a full bisect for the status "confirmed" is IMHO much over the edge, especially as it takes some time to trigger the bug. @PocketSam Although Chrisopher's advice is right to follow, if you gather the information with which mainline kernel the bug disapers it would still be g
