b9c55b6e2cc4369b0688961fa5de0e057f3ec0c4: fixed I noticed that in the broken kernel, plymouth does not switch on the external monitor. Normally plymouth shows a cloned display.
Looking at the remaining commits, there was a merge of tag "drm-intel- next-2017-07-17" which had a very large number of i915 commits. You may want to manually choose commits either side of that merge, to hurry things along, since I don't think git-bisect will descend into the branch until the merge commit is fully isolated. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1742602 Title: Blank screen when starting X after upgrading from 4.10 to 4.13.0-26 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1742602/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
