Bug description:
  [Impact]
  On the machine of Lenovo M715, there is an AMD GPU (1022:15dd rev ca), when it
  switchs to amdgpufb, the screen displays abnormally, we tested with a couple 
monitors,
  all of them can reproduce this issue.

  [Fix]
  Backported 3 patches from mainline kernel, all of them focus on the change of
  disable_vga(). After applying these 3 patches, the issue disappears.

  
  [Test Case]
  boot the system, run glxgears, everything works well

  [Regression Potential]
  Very low, these patches come from upstream, and I have tested them on at 
least 6 different
  lenovo machines and those machines have different AMD GPUs on them, all of 
them worked
  as well as before.

2018-10-24 Thread Brad Figg
This bug is awaiting verification that the kernel in -proposed solves
the problem. Please test the kernel and update this bug with the
results. If the problem is solved, change the tag 'verification-needed-
bionic' to 'verification-done-bionic'. If the problem still exists,
change the tag 'verification-needed-bionic' to 'verification-failed-
bionic'.

If verification is not done by 5 working days from today, this fix will
be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how
to enable and use -proposed. Thank you!

Bug description:
  [Impact]
  On the machine of Lenovo M715, there is an AMD GPU (1022:15dd rev ca), when it
  switchs to amdgpufb, the screen displays abnormally, we tested with a couple 
monitors,
  all of them can reproduce this issue.

  [Fix]
  Backported 3 patches from mainline kernel, all of them focus on the change of
  disable_vga(). After applying these 3 patches, the issue disappears.

  
  [Test Case]
  boot the system, run glxgears, everything works well

  [Regression Potential]
  Very low, these patches come from upstream, and I have tested them on at 
least 6 different
  lenovo machines and those machines have different AMD GPUs on them, all of 
them worked
  as well as before.
