#6: It says different over there. Nevermind. I don't want to break my system, since I need it.
I was able to boot with an old 3.13.0-kernel, still lingering in my grub menu. And I can confirm that everything works perfectly well with that kernel. I also can confirm that my suspicion with the iommu seems to be wrong, since with this kernel it shows the same line; that is it doesn't recognize the bug on Ironlike neither, and yet comes up properly. In a nutshell: since it runs perfectly okay on an old kernel, I dare to add 'Confirmed', though without any 'upstream' -attribute. I also add the dmesg with that kernel. Maybe the experts can spot the difference that make the screen flicker. At least, I hope so. ** Attachment added: "Screen works perfectly okay with old kernel - dmesg" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1712508/+attachment/4940882/+files/dmesg_3_13_0_46 ** Changed in: linux (Ubuntu) Status: Incomplete => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1712508 Title: Disappearing screen and flickering after upgrade to 16.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1712508/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
