Sorry about not finishing the bisection. I was dubious about the prospect of finding a nice clean patch to cherry pick in that drm-intel branch. But this is superseded now by the upgrade of linux-generic- hwe-16.04 to 4.15, which does not have the same issue. I recommend closing this bug as fixed, and discussing the unrelated blank screen issues elsewhere. A blank screen is a failure mode, not a specific bug. Anyone seeing a blank screen in 4.14 or later is not experiencing the same issue. This was an i915 bug in the 4.13 kernel. -- 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

Can you see if v4.14-rc1 fixes this issue: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.14-rc1/ To perform the bisect, we need to identify the last bad kernel and the first good one. ** Changed in: linux (Ubuntu) Importance: Undecided => High ** Changed in: linux (Ubuntu) Status: Confirmed => Incomplete ** Tags added: kernel-da-key ** Also affects: linux (Ubuntu Artful) Importance: Undecided Status: New ** Changed in: linux (Ubuntu Artful) Status: New => Incomplete ** Changed in: linux (Ubuntu Artful) Importance: Undecided => High ** Changed in: linux (Ubuntu Artful) Assignee: (unassigned) => Joseph Salisbury (jsalisbury) ** Changed in: linux (Ubuntu) Assignee: (unassigned) => Joseph Salisbury (jsalisbury) -- 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
[Bug 1742602] Re: Blank screen when starting X after upgrading from 4.10 to 4.13.0-26
I booted various mainline kernels from http://kernel.ubuntu.com/~kernel- ppa/mainline/?C=N;O=D * 4.11.12: works * 4.12.14: fails * 4.13.16: fails * 4.14.2: works * 4.14.13: works * 4.15-rc7: works So it would seem that the issue was introduced upstream in 4.12 and fixed in 4.14. -- 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
[Bug 1742602] Re: Blank screen when starting X after upgrading from 4.10 to 4.13.0-26
I have just had the same issue. Blank and frozen screen after booting in to 4.13.26 for the first time. The ubuntu colours are visible and the 16.04 logo also appears bottom left. The desktop was previously configured to run in 1920x1080. However, the screen changes to 4:3 ratio. No mouse or keys so unable to confirm the actual resolution. I assume it is a default. I followed another report before finding this one so deleted the .config directory. Ubuntu booted up to a desktop in default resolution. However, the screen then locked when changing the resolution. Ubuntu 16.04 desktop running inside KVM. So no special graphics installed to speak of. The image is encrypted with LVM inside the qcow file. Requires a password to boot after the grub menu. KVM hypervisor still running 4.10. Took a deep breath, rebooted and brought the hypervisor up on 4.13. Still the same issues. ssh on to the desktop machine continues to work fine even when the graphics are blank and frozen. Followed the workaround above, booted in to 4.10 via grub and everything springs back to life as expected. Able to put the desktop back to 1920x1080. Further reboots into 4.10 maintain that resolution. -- 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

I ran apport-collect, selected "keep", and edited the resulting file to remove private information. But I couldn't find any way to upload such a file to an existing bug report. ** Changed in: linux (Ubuntu) Status: Incomplete => Confirmed ** Attachment removed: "dmesg" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1742602/+attachment/5034871/+files/dmesg -- 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
