** Summary changed: - Kernel 4.4x results in blackscreen - Intel Ivybridge + Kernels 4.3-4.8 result in blackscreen - Intel Ivybridge
** Description changed: When I install Ubuntu 16.04 on my computer the screen goes blank at login. I can blindly login and it boots but I cannot use the display (external monitor through HDMI). I've looked online for an answer to this issue but could not find a solution. However, many people report this issue in forums with the 4.4x kernel. On my main computer, I upgraded from 14.04 to 16.04.1. On this computer I was able to switch back to the 3.13 kernel which *does work*. On the same computer, if I use a 16.04 live CD, it does the same thing. The screen goes blank. UEFI may be part of the issue as well. I have it disabled in bios (set to legacy mode) but when I first boot, it seems to go into UEFI mode first and then, after rebooting with <ctrl><alt><delete> it shows me the list of kernels. I can select the kernel from there but if I use a 4.4x kernel, it blanks out at encryption passphrase screen. There are also people with similar issues on AskUbuntu. Here's some basic HW info. If you require more, please ask. - sudo lshw | head - zbox - description: Notebook - product: ZBOX-ID18 (NA) - vendor: ZOTAC - version: XX - serial: GXXXX211XXXXX - width: 64 bits - capabilities: smbios-2.7 dmi-2.7 vsyscall32 - configuration: boot=normal chassis=notebook family=NA sku=NA uuid=00020003-0004-0005-0006-000700080009 - *-core - + zbox + description: Notebook + product: ZBOX-ID18 (NA) + vendor: ZOTAC + version: XX + serial: GXXXX211XXXXX + width: 64 bits + capabilities: smbios-2.7 dmi-2.7 vsyscall32 + configuration: boot=normal chassis=notebook family=NA sku=NA uuid=00020003-0004-0005-0006-000700080009 + *-core sudo lshw -C display - *-display - description: VGA compatible controller - product: 3rd Gen Core processor Graphics Controller - vendor: Intel Corporation - physical id: 2 - bus info: pci@0000:00:02.0 - version: 09 - width: 64 bits - clock: 33MHz - capabilities: msi pm vga_controller bus_master cap_list rom - configuration: driver=i915 latency=0 - resources: irq:45 memory:f7800000-f7bfffff memory:e0000000-efffffff ioport:f000(size=64) - + *-display + description: VGA compatible controller + product: 3rd Gen Core processor Graphics Controller + vendor: Intel Corporation + physical id: 2 + bus info: pci@0000:00:02.0 + version: 09 + width: 64 bits + clock: 33MHz + capabilities: msi pm vga_controller bus_master cap_list rom + configuration: driver=i915 latency=0 + resources: irq:45 memory:f7800000-f7bfffff memory:e0000000-efffffff ioport:f000(size=64) lsb_release -rd Description: Ubuntu 16.04.1 LTS Release: 16.04 - --- + --- ApportVersion: 2.20.1-0ubuntu2.1 Architecture: amd64 AudioDevicesInUse: - USER PID ACCESS COMMAND - /dev/snd/controlC0: rmezger 5536 F.... pulseaudio + USER PID ACCESS COMMAND + /dev/snd/controlC0: user 5536 F.... pulseaudio DistroRelease: Ubuntu 16.04 HibernationDevice: #RESUME=UUID=edaa55c6-eb56-43fb-8004-495948b72b38 InstallationDate: Installed on 2014-07-23 (743 days ago) InstallationMedia: Ubuntu 14.04 LTS "Trusty Tahr" - Alpha amd64 (20140313) MachineType: ZOTAC ZBOX-ID18 Package: linux (not installed) ProcEnviron: - LANGUAGE=en_US - TERM=xterm - PATH=(custom, no user) - LANG=en_US.UTF-8 - SHELL=/bin/bash + LANGUAGE=en_US + TERM=xterm + PATH=(custom, no user) + LANG=en_US.UTF-8 + SHELL=/bin/bash ProcFB: 0 inteldrmfb ProcKernelCmdLine: BOOT_IMAGE=/vmlinuz-3.13.0-92-generic root=/dev/mapper/ubuntu--vg-root ro quiet splash ProcVersionSignature: Ubuntu 3.13.0-92.139-generic 3.13.11-ckt39 PulseList: - Error: command ['pacmd', 'list'] failed with exit code 1: Home directory not accessible: Permission denied - No PulseAudio daemon running, or not running as session daemon. + Error: command ['pacmd', 'list'] failed with exit code 1: Home directory not accessible: Permission denied + No PulseAudio daemon running, or not running as session daemon.
