[Bug 1596216] Re: Black screen on boot; no modeset workaround broken by 16.04


Joe Helfrifch, in order to allow additional upstream developers to examine the issue, at your earliest convenience, could you please test the latest upstream kernel available from http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D ? Please keep in mind the following:
1) The one to test is at the very top line at the top of the page (not the daily folder).
2) The release names are irrelevant.
3) The folder time stamps aren't indicative of when the kernel actually was released upstream.
4) Install instructions are available at https://wiki.ubuntu.com/Kernel/MainlineBuilds .

If testing on your main install would be inconvenient, one may:
1) Install Ubuntu to a different partition and then test this there.
2) Backup, or clone the primary install.

If the latest kernel did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this issue is fixed in the mainline kernel, please add the following tags by clicking on the yellow circle with a black pencil icon, next to the word Tags, located at the bottom of the report description:

Where X, and Y are the first two numbers of the kernel version, and Z is
the release candidate number if it exists.

If the mainline kernel does not fix the issue, please add the following tags:

Please note, an error to install the kernel does not fit the criteria of

Also, you don't need to apport-collect further unless specifically
requested to do so.

Once testing of the latest upstream kernel is complete, please mark this
report Status Confirmed. Please let us know your results.

Thank you for your understanding.

  Black screen on boot; no modeset workaround broken by 16.04

Status in linux package in Ubuntu:

Bug description:
  This bug appears to occur in several distros and architectures.  On
  this machine, it appeared somewhere in the last week of January, 2016,
  after a system update.

  On boot, the laptop monitor often flickers several times (signal
  connecting and disconnecting) and always settles onto a full backlight
  back screen.  The screen does not change after that.

  I found reports that adding nomodeset to the grub parameters would
  resolve the issue.  It does, but the workaround has significant issues
  in 16.04.  The nomodeset parameters conflict with both the amdgpu
  driver package and the radeon driver package.  When the machine boots,
  it is in 800x600 resolution.  While I can add new resolutions,
  attempting to switch to them with xrandr throws the error "configure
  crtc0 failed"
