The problem is only reproducible with some Kernel versions, how can it not be related to the Kernel? I actually have a Sky Lake, not a Haswell like the reporter. So maybe one of those commits for Baytrail caused a regression on other Intel Graphics processors?
Another culprit seems to be Dell laptops... I'm on a Dell Latitude E7470, other people mentioned them too, although it might just be because it's a common brand. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1686189 Title: External monitor connecting problem on Intel graphics card To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1686189/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
